Machine Learning

Machine learning seems to be a big trend for either today's research or the IT industry. There are quite a number of business ideas hanging around my head, most of which require machine learning for a good outcome.

First idea is a products-comparison application which help consumers to better compare similar products from different online retailers. This is going to solve the pains for the consumers who would like to buy certain products from all the possible overseas retailers and ship to their homes. The consumers need to spend a lot of time comparing different solutions(including the price of the product and the price of the shipment) and the solutions are mostly not optimal. The idea is not new. But with the evolving development of mobile clients, this idea has a very big market. As is shown in one survey, 70% of the smartphone users use their smart phones to compare different products. The comparison service itself can generate a fairly good revenue from ads, even we only focus on one specific market, e.g.,electronics devices or cosmetics. If it works well, the application can make its own online-retailing service later, or even enter the logistics market in a more ambitious stage.  Machine learning and information retrieval would be two powerful tools to make it work.

Another idea is to make a lyrics-melody match application. When a lyrics writer writes a piece of lyrics, he/she would love to find a piece of melody which fit the lyrics the best. The same for a melody writer. It is a fairly rare case that an amateur can write a complete song with nice lyrics and melody fitting each other. Machine learning and information retrieval come into play again.

That's not easy. Everything is not easy if we want make it work nicely. It's good that I am taking the machine learning course in which makes me really interested. Hope some of the ideas can work someday.

Yesterday, I visited a Start-up company in NTU incubator center. This company was formed a year ago by three undergraduates from China. Unlike many recent start-ups which mainly develop mobile apps, they provide enterprise solutions for multimedia companies. One of their products is to make interactive painting gallery display using LCDs and Microsoft Kinect.  Another product is to provide car-dealers with interactive display using Kinect. The company is able to maintain its daily operations with no pays to its team members. The core team consists of one very good programmer, one charismatic business guy, one OK programmer with good strategic planning and one designer+business women. That's a fairly good distribution.There are even some team mates who are willing to work for the team for free. That's really passionate.
I talked with the CTO and he shared quite a number of interesting ideas. Regarding machine learning:
1. How apple's wifi determines the location of a user? It's not via the computation of the nearest wifi transmitters, but via the location data from other IOS devices which appear in that region.
2. Google abstracts some ambiguous characters from scanned books and make them into reCAPTCHA. The unknown words are then recognized by the probability of the human inputs. The recognized words are then reusable again in Google's ebook projects.
3. How Google knows the traffic conditions of a certain place? In some places where location data are not allowed to be collected from Android, they simply count the number of Android devices in that region and infer the traffic condition.
Regarding the start-up environment here in Singapore. Singapore is very suitable for creating start-ups. The situation here in Singapore is opposite with that of China. In China, there are a lot of very good programmers but not many kinds of funding. But in Singapore, there are various kinds of funding, however, not so many good projects and good programmers.

Once again, I get to know that great products are coming from simple ideas but very good executions. Another time, you need to know some business stuffs, pure programmers are cheap.

Something good worth mentioning for this week:
1.I swam 4 times this week. Body fitness is so important.
2.I wrote the lyrics for my first pop song out. It happened to be about "faith", like a religious song.


Something bad worth mentioning:
1. I slept very late on Friday(3am) to watch the Voice of China TV show, which makes me sleepy for the whole weekends. Shall have a more regular schedule.
2. Last week passed so quickly, can be more efficient.


  1. "not so many good programmers" and "a lot of funding" hmmm....

    好idea 要做做看,搞个side project嘛

InnovFest 2015

I attended the innovFest 2015 event. It was quite eye opening. Besides the booth, some topics in the forums also interested me. The first topic I joined was the Kopi Chat with Yossi Vardi, a famous Israeli entrepreneur and investor. He is straightforward and humorous. When talking about the most important reason why people wake up with a great idea but ended up sleeping without executing anything, he collected answers from the audiences. One answer pretty much fitted his appetite-- "People fear about losing faces". He shared his opinion with the quotes from Theodore Roosevelt, “It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually st


I've been working as a project manager on an interesting project named " Dadafish " for quite some time. The intention is to create a sharing economy platform for lifestyle teaching/learning. Put in a more straightforward way, an Airbnb for classes. There is one assumption:  People are willing to pay to learn skills from amateur or semi-pros at a lower price. Quite some ongoing arts classes in meetups are taught in cafe shops at 15-50SGD/session. It's an indirect validation of our assumption. There are also many free language classes in meetups and facebook groups. We did an experiment to validate the assumption by introducing a Japanese friend who's organizing a free meetup to teach Japanese. She doesn't have a certificate and she's currently teaching Japanese in meetups for free. The experiment class was charged at 15 SGD/h per person for a 3-4 pax group class. We posted the class and teacher info in a NUS student/alumni SNS group and three peopl

Consistency Matters

I didn't post anything last week, which means consistency has been broken. There's a need to reflect the task management skills, otherwise I'm very likely to driving the wrong road Priority changes. A good exercise would be to list the priorities down everyday and assign reasonable time to the tasks. Then never second-doubt. 100% focusing on the task when doing it. Priority changes from time to time.  Human minds are single-threaded, thus, we'll need to keep focused when doing one particular task. Be Grateful. I received the confirmation from NOC Israel that I got admitted by the programme and I'm heading to Israel next Jan:-) Thanks a lot for Prof.Ben and Karl's help. Ultimately, it might be a plan from God. Thanks every one. The additional interview from Google went well, however, I didn't get the winter intern opportunity this time. Though it's a bit too greedy to ask for too much, I still feel a bit sad after informed that I didn't get th
