Big data and machine learning are all the rage now. Articles in the popular press inform us that anyone who can master the skills needed to turn giant piles of previously unexplored data into golden nuggets of business insight can write their own ticket to a fun and remunerative career (efinancialcareers May 2017).

Conversely, the press also tells us that if we don’t learn these skills a computer will take our job (USA Today Mar 2014). I will have a lot more to say about changes in employment and income during the industrial revolution in future blog posts.

But how do you learn to become a data scientist. And which software stack should one specialize in? There are many tools to choose from. Since I live in the Seattle area and do a lot of work for Microsoft, I decided to do take an online class developed and sponsored by Microsoft and edX. Completion of the course leads to a Microsoft Data Science Certificate.

The program consists of 10 courses with some choices, like conducting analysis using either Excel or Power BI, and programming using either R or Python. Other parts of the Microsoft stack you will learn include SQL Server for queries and Microsoft Azure Machine Learning (MAML) for analysis and visualization of results. The courses are priced about $99 each. You can audit them for free if you don’t care about the certificates.

I started the program in February and am about half way done. In case any clients or potential employers are interested in my credentials, my progress is shown below.

DAT101x – Data Science Orientation

If you haven’t been in college in a while or have never taken an online class, this is a good introduction to online learning. The homework consists of some simple statistics and visualization problems.

Time: 3 hours for 3 modules

Score: 100% on 3 assignments

DAT101x Score    DAT101x Certificate

DAT201x – Querying with Transact-SQL

I took a t-SQL class online at Bellevue College two years ago. Taking a class with a real teacher, even one you never meet, was a significantly better experience than a self-paced mooc. This course starts with the basics like select, subqueries, and variables. It also covers intermediate topics like programming, expressions, stored procedures, and error handling. I did my homework using both a local instance of SQL Server and on an Azure SQL database.

Time: 20 hours for 11 modules

Score: I missed one question in the homework and two in the final exam for a combined score of 94%

DAT201x Score     DAT201x Certificate

DAT207x – Analyzing and Visualizing Data with Power BI

I already have experience creating reports using Power BI. I also use Power Query (now called get and transform data) and M language and Power Pivot and DAX language, so this was an easy class.

The course covers data transforms, modeling, visualization, Power BI web service, organization packs, security and groups. It also touches on the developer API and building mobile apps.

Time: 12 hours for 9 modules

Score: I missed one lab question for a combined score of 98%

DAT207x Score     DAT207x Certificate

DAT222x – Essential Statistics for Data Analysis using Excel

This class is comprehensive and covers all the standard statistics and probability topics including descriptive statistics, Bayes rule, random variables, central limit theorem, sampling and confidence interval, and hypothesis testing. Most analysis is conducted using the Data analysis pack add-in for Excel.

Time: I used to work in market research, so I know my statistics. However, there are 36 homework assignments and it took me over 20 hours to complete the 5 modules.

Score: I missed 9 questions on the quizzes (88%) and six in the final exam (81%) for a combined score of 86%. (Despite the time it takes to complete, homework counts very little toward the final grade)

DAT222x Score     DAT222x Certificate

DAT204x – Introduction to R for Data Science

Now we are getting into the meat of the program. R is a functional language. In many ways it is similar to the M language used in Power Query. I was able to quickly learn the syntax and grasp the core concepts.

The course covers vectors, matrices, factors, lists, data frames, and simple graphics.

The lab assignments use DataCamp which has a script window where you write code and a console window that displays results. That makes it easy to debug programs as you write them.

Time: 15 hours for 7 modules

Score: I got all the labs right and missed two questions in the quizzes. The final exam used an unexpected format. It was timed and consisted mostly of fill-in-the-blank responses. You are given 4 minutes per question. If you don’t answer within the time limit, it goes to the next question. I completed the test in about 70 minutes and was exhausted at the end. I only got 74% on the final (I don’t know how many I got wrong or the total number of questions), for a combined score of 88%

DAT204x Score     DAT204x Certificate

DAT203.1x Data Science Essentials

The first three modules in this course covered statistics and was mostly a repeat of the material introduced in DAT222x. But the rest of the course provides an excellent introduction to machine learning. You learn how to create a MAML instance, import a SQL query, manipulate it using R or Python, create a model, score it, publish it as a web service, and use the web service to append predictions as a column in Excel. I really like MAML. I will post a review of my experience in a future blog post.

The course was a little too cookbook-like for my taste. It consisted mostly of following directions to drag-drop boxes onto the canvas UI and copy-paste code snippets into the panels. However, if you want a quick introduction to machine learning without having to dig into the details of SQL, R, or Python, this is a great course.

Time: 10 hours for 6 modules

Score: 100% on the 6 labs and the final

DAT203.1x Score     DAT203.1x Certificate

I have now completed six out of the ten courses required for a certificate. I expect to finish the remaining 4 needed for a certificate by the end of the year. I will also probably take some of the other elective courses simply to learn more about Microsoft’s other machine learning and cloud services.

I love moon pies (apparently, I was a southerner in a past life). Surprisingly, they are big in South Korea too (who knew, for history see Wikipedia).

Incidentally, don’t confuse moon pies with moon cakes which are another Asian sweet (which I usually don’t like because of the salty egg flavor).

Anyway, today, I found a really cheap source of my favorite confection. Lotte brand is $3.50 for 335g or 29 cents a pie. Mysteriously, they are hidden next to weird spices in the international food aisle, not prominently displayed with the other cookies in the snack aisle. Perhaps it’s a form of American food protectionism by US cookie makers, Asian segregationist policy or redlining by the store, or the result of some other nativist conspiracy plot.

It’s crazy that a South Korean company can import all the ingredients, process them, ship them back to the U.S., and still be cheaper than US-made cookies. But I don’t care as long as I get my fix of graham cracker, marshmallow, and sugary goodness.

I just returned from a short trip to New York. I have been to the city many times, but not recently. So I took time to go to places that are new since my last visit in 2009.

Cooper Hewitt Smithsonian Design Museum

As a software program manager, the Cooper Hewitt is one of my favorite museums. It recently completed a major renovation (Press Release, Dec 2014). I was looking forward to seeing the redesigned design museum and was not disappointed.

Upon entering the museum, each visitor is given a stylus and a code number. The stylus is a bit bulky but is rugged. The pointed end can be used with large touchscreen monitors (probably Microsoft PixelSense devices since the newer Surface Hub wasn’t released until after the museum opened) scattered around some rooms. Visitors can select images, write text, and draw images on the touchscreens. Visitors can tap the other end of the stylus to the touchscreens to save their work. They can also tap on exhibit signs to save them and get more information for later.

On the second floor is a cubical Immersion Room that contains another large touchscreen monitor. On this one, visitors can select wallcovering patterns from the Cooper Hewitt collection or design their own using the pen. They can save their patterns and project them on the walls of the room. It is a very enjoyable experience to see your pattern fill the room (see photo above).

After your visit, you can go to the Cooper Hewitt website, create an account, enter your code, and review your visit and further explore exhibits that interested you. If you are a developer or tinkerer, check out the Toys section to use the API and to access anonymized visitor data.

Museum of Modern Art

The Museum of Modern Art is not new yet. However, since my last visit, MoMA has announced a major expansion. An increase of 4,600 sq. m (50,000 sq. ft) will add about 17%  of new space the the already large museum. Construction has started, though it hasn’t caused any closure of the current space for now.

The addition is expected to be well integrated with the existing museum. Construction will take over four years to complete (Curbed New York, Jan 2016).

I saw a special exhibit on Bruce Conner (1933-2008) an avant garde painter, sculptor, photographer, and film maker (see photo). The show was organized by the San Francisco Museum of Modern Art. In an ironic twist, I was unable to visit the newly remodeled SFMoMA while I was in SF in April since it was still closed for renovation (see SF Gate, May 2016).

The expansion of MoMA required the demolition of the American Folk Art Museum, which was a lovely bronze-clad building next door to it. (I saw a wonderful special exhibit on quilts during my last visit to New York.) The building is already gone and is now just a hole in the ground. The museum has moved to Columbus Avenue between 65th and 66th Streets.  I didn’t have time to visit it.

9/11 Memorial & Museum

The National September 11 Memorial opened in 2014. It honors the victims killed in New York, Washington, DC, and Pennsylvania during of the awful attacks in September, 2001 as well as the people killed in the earlier attack on the World Trade Center in February, 1993.

The memorial consists of two square fountains, each encompassing the footprint of one of the towers. The fountains are surrounded by bronze panels with the names of each victim cut into them. A white rose is placed by each name on that person’s birthday (see photo). Water falls about 10 m (30 ft) into a reflecting pool. From there, it falls into a square hole so deep you cannot see the bottom. The sound of rushing water is emitted from the hole. The scale of the fountains is moving. Even on a busy summer weekend when thousands of tourists are viewing the memorial, there is plenty of space to stand and contemplate.

The 9/11 museum is also enormous and also within the footprint of the towers. The main floor is under the fountain about 18m (60ft) below ground. From the balcony you can see the slurry wall that holds back the Hudson River and a giant remnant of a column from the World Trade Center marked with spray paint (see photo).

An escalator takes you past a quote translated from Virgil’s Aeneid, “No day shall erase you from the memory of time” (see photo). The quote is surrounded by 2,983 watercolor paintings, one for each victim, by Spencer Finch recalling the shade of blue of the sky on the morning of 9/11.

Overall, the museum does a good job of explaining the events leading to the attack and the recovery effort afterwards. One can imagine the difficult task of presenting an evenhanded account in the face of enormous pressure from victim families, first responders, government agencies, donors, and politicians. Nearly every artifact and photo is heavily researched and annotated, which is somewhat chilling. One gets a sense of how invested the survivors are in preserving the memories of the loved ones lost in the attacks.

As a side note, when viewed in context, the use of the Virgil quote above is rather controversial. The “you” refers to the attackers, not the victims, giving it a very different meaning than what was intended (NY Times, Apr 2011). Yet the alternate interpretation is also true. Because of the horror they caused, we will not forget the attackers either.

The Cloisters

The Cloisters is part of the Metropolitan Museum of Art. It houses artwork and architectural fragments from twelfth to fifteenth century Europe. The building is shaped like a medieval cloister and is located at the top of a hill in Fort Tryon Park in northern Manhattan (see photos).

I’m not a big fan of art from this era, so have never bothered to go all the way up to the Cloisters. But after visiting Florence a few years ago I decided I should make the journey. It was well worth it. I took the subway and walked up the hill. The building is imposing.  The gardens are tranquil and beautiful. And seeing the historical transition in painting from flat to perspective is fascinating.

Dyckman Farmhouse Museum

On my way to the Cloisters, I accidentally missed my stop. Rather than wait for a train the other direction, I decided to walk back. On a busy street filled with businesses I suddenly passed by a small garden and walked in. It turns out it was part of the Dyckman Farmhouse Museum. Opened in 1916, the museum is not very large, but is well maintained and reveals some of the history of Manhattan beginning with the Revolutionary War.

Final Notes

When visiting a city, I rarely buy City Pass tickets or their equivalents. The list of venues is fixed and limited. Instead, I just buy tickets in advance directly from each museum I visit. In fact, I just go to each museum first, checked out how long the line is, and if it is too long, then use my phone to buy tickets online. Museums with long lines and that lack online ticket sales don’t get my business.

To get around a strange town, I need more than a map. I need info on the best ways to get around by walking, biking, using public transit, or hailing Uber. Also, I want to compare estimated travel times and costs for each option. I have found two excellent apps to help. They are CityMapper and Transit, both available for iPhone and Android.

Last Saturday, I attended a free class sponsored by the Cascade Water Alliance, an association of several water districts in Western Washington. The class, entitled Landscaping in the Northwest without the Need for Automatic Sprinklers, was held in Sammamish, an eastern suburb of Seattle. It was taught by noted local plant writer and speaker Marianne Binetti. It was a great class and I learned a lot. Probably the most important thing I learned was to not be intimidated by plant names. There are thousands of varieties of ornamental plants and you can’t know them all. Just go to the nursery with a plan to buy water-conserving plants, ask for help, and pick things you like.

Ironically, it is raining today. But I know that come summer, the Puget Sound region will have three dry months. Our house has a big yard and out in the suburbs water is very expensive. I want to learn how to design and build a low maintenance/low irrigation landscape for our yard. And you can’t beat the price of a free class.

My wife Sue and I attended a similar class back when we lived in Denver. That class featured a technique called xeriscaping and was taught by the Denver Water Department. Denver is much drier than Seattle (15-inches rain per year in Denver vs. 38 inches in Seattle). However, we had a city house with a tiny yard plus water was much cheaper due to the senior water rights held by the city.

Both the Denver low-water xeriscaping class and Saturday’s no-water class covered how to choose drought-tolerant and freeze-tolerant plants like succulents, hardy perennials, and prairie grasses. These plants are not necessarily native to the respective regions, but will grow there and look appealing. Both classes also offered information on proper soil amendment, and mulching to minimize or eliminate the need for irrigation.

Enough description about the classes. Below are the notes I took during Ms. Benetti’s lecture. I took the notes on a 6-inch square notebook I received from Northwest Kidney Centers using a pen with black ink. I cut the pages out of the book, added the colors using felt-tip highlighter pens, and scanned the pages. Enjoy!

It was raining all day, keeping me from doing yard work this afternoon. That’s my excuse and I’m sticking to it. So I started doodling and came up with an invention to keep exterior concrete steps from getting covered with puddles of water.

My idea is to use a hard rubber mold on top of each tread to cut notches in the step that act as gutters to guide the water down to the next step down.

The drawing below shows the cross-section of a typical concrete step with a 11-inch tread and 7-inch riser. The tread has a series of 1-inch wide triangular grooves molded into it. The grooves are sloped down the tread. The groove is 1/8-inch deep at the start of the tread (cross-section AA) and reaches 1/2-inch deep (to become 45-degrees) at the end of the tread (cross-section BB).

The design has several nice features.

  1. Unlike most concrete steps, the treads are not sloped. The tops of the grooves are level to the ground. This improves safety. You won’t slide, and potentially fall, when the steps are wet, muddy, or icy
  2. The grooves shed water from the treads. This keeps water from forming puddles on the treads even if the concrete for the steps is poured slightly off-level
  3. The grooves reduces the contact area between the step and your shoes, to increase traction, which again improves safety

ConcreteSteps

I’ve never seen concrete steps with grooves like this. So either I am the first person to think of this, or my design is a solution in search of a problem that doesn’t exist.

This is a continuation of the story of the Taniwaki family tree with biographies of generations 5 through 8. The stories of generations 1 to 4 are in a Jan 2014 blog post. If you are one of my relatives, please provide information to complete these stories.

TaniwakiFamilyTreeAnon

Eight generations of the Taniwaki family tree

Fifth generation

Tatsui Taniwaki 谷脇達意

Tatsui was born in the 1890s as the eldest child of Umetaro and Tsuru. She married Nobushi Yokoyama. They lived in Taiwan (which was a Japanese colony at the time) for several years. She died in the 1990s.

Nobushi Yokoyama 横山農夫志

Nobushi was a school teacher in Taiwan. He also managed rental property owned by Tsuru, his mother-in-law. Without consulting her, he mortgaged the houses to start his own business, planning to secretly pay her back from the profit. His plan failed and Tsuru lost the houses to the bank. Tsuru’s book showed the last entry was in 1931. The relation between them could not be worse.

After the war, Nobushi, Tatsui, and their son Shizuo moved back to Japan and lived in one of Tsuru’s rental houses.

I don’t know if Nobushi is related to Yasukichi (Matsu’s husband) or if the same family name is a coincidence.

Kiyomi Taniwaki 谷脇清実

My father was born in 1901 in Japan as the second child and elder son of Umetaro and Tsuru. Umetaro left for the U.S. in 1904 and Tsuru followed in about 1909. He was left with his grandparents who did not treat him well. At age 16, he came to America where he worked mostly as a farm laborer with the intent of buying his own farm.

In 1924, the U.S. passed a restrictive immigration law that would effectively prevent new immigrants from Japan from entering. Kiyomi hurried back to Japan and married Sadai and returned with her to America.

Around the same time, the U.S. Supreme Court ruled that California’s Alien Land Law was constitutional. This made it illegal for Japanese immigrants to own or lease farmland. Kiyomi continued to work as a farm laborer. He did a good work fast and preferred piecework over hourly rates. He made $5 a day (about $100 in 2010 dollars, which was quite high for farm labor).

But since he could not own a farm, his work required moving from one farm to another. This was not suitable for a family man. He got a job in Hayward and worked for a carnation grower, Fujii Nursery. Now with a steady job, Kiyomi and Sadai had two children, Michio (me) in 1926 and Hideko (my sister) in 1931.

TaniwakiKiyomiSadaiMichio

Sadai, Michio, and Kiyomi Taniwaki, circa 1929

Around 1928, someone from Tsuru’s family wanted to come to America for school. This required a U.S. sponsor who could cover any liability. Kiyomi asked the nursery owner, Fujii to be the sponsor and he accepted. The young man got involved in a quarrel with another student and injured him. This was potentially a large liability case and Kiyomi would do anything to keep Fujii out of it. He sought help from Shigeki Oka, a man from the same prefecture. He paid Shigeki $200 (about $3500 in 2010 dollars), but he didn’t do anything. In the end, Kiyomi somehow managed to make the young man go back to Japan and convinced the victim to not claim compensation from Fujii.

With the onset of the depression, Kiyomi wanted to take his family back to Japan. But because of this legal problem, the trip was delayed until December, 1932.

When the family returned to the farm, his aunt Tomi and her husband Unkichi did not have place to go, so Kiyomi gave them the house that his grandfather Eiji built many years ago and gave them 100 yen (about $1000 in 2010 dollars, but several months cash income in rural Japan) to disassemble it and move it to a new location.

Kiyomi built a two-story house for his family. People described it “as big as a school-house.”

In 1937, the Japanese army invaded China. Because he had not served in the army when he was younger, Kiyomi was called to service at the late age of 36. He served in the Supplementary Transport Unit. There, he often met English-speaking people. Despite differences, the Chinese referred to him as a gentleman. He came home after six months.

Kiyomi died on 1987 Dec 13.

My father told me the following stories about our farm. Our farm once had large camphor trees, a prominent landmark. One day, a local official, who was seeking recognition or a promotion, ordered the tress cut down in order to make camphor blocks that the local lord could use to protect his clothes from moths. Our family was discouraged by this and quit growing camphor trees.

He also said in late 1930s, the area was covered with network of tree roots. Leftover wood was used to make hibachi (stoves used to warm hands, not to be confused with the cooking devices known in the U.S.). I remember seeing two of them, the larger one was about 70 cm (2 foot) in diameter.

Sadai Ono 小野貞意

My mother was born on 1905 Jan 7 and married Kiyomi in 1924 and immediately moved to the U.S. She and Kiyomi had two children born in the U.S. before moving back to Japan in 1932. She died on 1986 Feb 26.

Sakae (Oski) Taniwaki 谷脇栄

Oski was born in 1903 in Japan. He had just started school when his mother, Tsuru, took him to America to join Umetaro.

Oski was a very quick learner of English. Only two month after moving to America, he came home from play and told his mother a story of  why the moon is yellow. He said in Japanese, “A woman was making butter. It didn’t turn out well, so she threw it away. It went high into the sky and became the moon.” He said he learned it from a  neighbor. Since the neighbor was not Japanese, he must have heard the story in English.

When his parents moved back to Japan in 1924, Oski remained in the U.S. and attended the University of California, Berkeley to become a pharmacist. However, while in school he realized that California would refuse to grant him a license because he was not a U.S. citizen, ending his dream.

Though everyone called him Oski, my uncle’s given name is Sakae. Oski is a nickname taken from the name of the bear mascot of UC Berkeley.

Oski was one of the founding editors of the New World Daily (Shinsekai nichinichi shinbun), a bilingual newspaper for Japanese immigrants in San Francisco.

In 1935, Oski went to Japan to look for a job since America was still in depression. He came to see us at Kochi prefecture first. Then he proceeded to Taiwan where Tatsui, his older sister, and her husband, Nobushi, were living. Nobushi came up with an English teaching position and English reporter work at a newspaper, but Oski didn’t like these jobs and returned to America.

In 1942, thousands of Japanese Americans living in the western U.S. were forced to evacuate their home and deported to internment camps under U.S. executive order 9066. Oski, Gladys, and their young son Hugo were among them. Each person could only carry a single suitcase. All homes, cars, and other possessions had to be disposed. Rather than sell their appliances and furniture at distress prices, Oski asked neighbors to store these items for them. After the war, he could not locate the neighbors. Everything they owned was gone.

While incarcerated in the Amache relocation camp near Granada, CO, Oski worked as an editor for the camp newspaper, the Granada Pioneer. Near the end of the war, Oski was released from the camp and employed as a taxi driver in Chicago.

After the war, the family moved to Denver, where a small Japanese-American community was growing. Oski died about 1986.

Shizue (Gladys) Ioka

Gladys was born about 1911 in California. She married Oski in the 1930s. They had two children, Hugo and Walter (Nobu). She ran a Japanese gift shop and bookstore called Kobun-sha in Denver (not to be confused with the magazine publishing company of the same name in Japan). She died about 2000.

Sixth generation

Shizuo Yokoyama 横山静夫

Shizuo is the only child of Nobushi and Tatsui. He graduated from Imperial University (now National Seven Universities) with a degree in agriculture. He worked for the kencho (prefectural government) until his retirement at age 60. He has come to America twice.

Kimiko [___] _公子

Kimiko married Shizuo in 1950s. She was a school teacher, now retired.

Michio Taniwaki 谷脇道雄

I am the elder child of Kiyomi and Sadai. I was born on 1926 May 30 in Oakland where a Japanese midwife had a clinic, but lived in Hayward California until December 1932. By then I was in a school. My family moved back to Japan where I had a hard time adjusting to the new life in Japan, but eventually became familiar with the environment.

By 1942, Japan was engaged in the Pacific war. My father paid tuition to enroll me in what was equivalent of high school. During this time I started a radio repair business.

After graduation, the war was still on and I was drafted and sent to Hiroshima to become a radio operator for one of the army owned ships. Before the training was complete, the atomic bomb was dropped. I was very lucky and was not injured. Details of my experience are published in a three-part Dec 2012 blog post.

After the war, I wanted to return to America, but encountered legal problems because of my dual citizenship. I had voted in Japanese elections and served in the Japanese army. I was unable to get a visa until 1953.

In the U.S., I lived in Hayward and worked for the same carnation grower as my father, Fujii Nursery. I also started a little TV repair shop in a rented house.

I married Hisae in 1958 and we had our first son, George. One day, Oski and Gladys visited us and invited us to move to Denver. We accepted. As of this year, we have lived in Denver for 52 years.

I have gone back to visit Japan four times since returning to the U.S. The first was in 1975 with the entire family. My children have been there more frequently than I have.

Hisae Ota 太田尚枝

Hisae was born on 1935 Nov 29 in Chongjin, a city in what is now North Korea which was then Japanese territory. She lived in a Japanese enclave and attended a Japanese school and doesn’t remember seeing any Koreans in the city. Hisae, her mother, grandparents, and five siblings all younger than her lived in the city. Her father, like most able-bodied Japanese men, was serving in the army.

Japan announced its surrender to the allies on 1945 Aug 15, but the Soviet Union did not recognize it. Instead, it invaded China and Korea. The Japanese army was already recalled leaving the Japanese civilians defenseless. Hisae and her family fled their home.

The Soviet airplanes used machine guns and bombs to attack the cities and then the convoys and trains carrying the fleeing civilians. With some exception, Koreans were not very friendly. Hisae’s family hoped to reach Busan, a port in southern Korea protected by the allied forces. This was a stressful undertaking. During the retreat, her baby brother and  both grandparents died.

In Japan, they reunited with her father and lived in Yamaguchi prefecture. Immediately after the war, food and medicine were scarce and a newborn baby sister died.

In 1956, the U.S. government allowed a small number of refugees to immigrate. Hisae’s family was accepted and they moved to San Pablo, CA. Their sponsor was the owner of Oshima nursery, a rose grower. I was working for a carnation grower in Hayward and had a friend working near the Oshima nursery, so I visited the area frequently. One day I met Hisae and two years later we got married in 1958.

Hugo (Kiyoshi) Taniwaki

Hugo was the elder son of Oski and Gladys. He was born about 1938 in CA. As a child his family was deported to the Amache relocation camp in Colorado and spent three years in confinement. He lived most of his life in Denver. He died in 2013 while in Phoenix, AZ.
