I was revisiting the thoughts I shared on Google+ during the last 3 years and I found a good idea. Just need to find some time to fool around with it.
 
Some thoughts about compression: Can we design some encoding that has each symbol mapped to multiple probabilistic values? The benefit is, during the process of decoding a sequence of words, the joint density of each possible outcome can be used to determine the result. This approach does not go beyond the lower bound of Kolmogorov complexity governing the maximum compression ratio in general case, but it may work well for frequent phrases, to some extent, pieces of information that we have prior knowledge of, such as texts and human languages.

Massive distributed neural network construction & the future of machine learning: unsupervised vs supervised
 
For machine learning people: TechTalks.tv just posted online my NIPS 2012 Workshop talk on Deep Learning + the Google project, plus my thoughts on some future research directions for ML and computer vision. If you watch any part of this and have comments, please post them below!

They only need $200k more. The deadline is two weeks from now. Here is the trailer of season 1: Video Game High School (VGHS) - Trailer and all the episodes: http://www.rocketjump.com/category/vghs . If you like it you can help them on the link below. I sponsored $300.

Can someone do a simulation? I don't believe the probability of winning could be doubled by changing the choice.

......
However, I must admit to finding the cited problems, in pure math, neither practical nor interesting. There was one old brain-teaser I found appealing and remembered for a little talk to a non-mathematical group. A well-known tv hostess with a super IQ caused a storm of controversy with it:

Suppose you are on a quiz show. You may choose to open one of three doors. One has a prize behind it, an other a booby prize. Suppose you choose one door but before you open it, the show hostess, opens another door which reveals no prize. The hostess then allows you to stay with your first choice or to choose, instead, the other unopened door. 
The question is: which is the best strategy?

The tv woman with the genius IQ said: change your choice. Letters at a rate of nine to one disagreed with her, including some academics, on the degenerate influence of tv, saying things like: you really blew it, this time! Their argument was that the move from one door to the other shouldnt make any difference, because there was an equal probability that the prize would be behind either still unopened door.

Of the little group, this reviewer talked to, some guessed right some wrong. None really know. I had thought like the ignorant ninety per cent. The interesting thing is that the most prolific mathematician of the twentieth century couldnt understand, either. Like a green student, he pestered his host and colleague for an explanation.

Erdös was shown a computer simulation of the quiz show given a large number of trials. On average, the probability of winning the prize was one-third, if one stayed at the door of one's first choice. If one changed one's choice, the probability of winning became two-thirds.
Erdös accepted the result but he still wanted a transparent explanation 'straight from the book'.
Erdös' friend and colleague put it this way. You, as the quiz contestant, know you are going to be given the chance of making two choices for the prize.

One of the many reasons I signed up Google Glass for. Also reminds me one of the Assassin's Creed III videos (unlocked when you levelled up to around level 30-40 in Multiplayer PVP mode)... Assassin's Creed III - Animus OS (Original + Hacked) with subtitles

The second part of this video is a lot more interesting: How quantum computing solves the local minima problem in machine learning, and how it can quickly solve NP-hard and NP-Complete problem.

(The first part of the talk is on feature learning and choice of features.)

I made some terrible scratch on the right front light and panel on a brand new hybrid rental car. It would cost me more $2000 to replace the light and repair the damage. I found Joe (the owner of this place) from here and left the car to him. He casted some magic on the car, and three days later, when I picked up the car from his workshop, it looked like nothing has ever happened to the panel and the light. He found a way to keep the light and repair it, and he did all these for only $1000 - which he saved $1000 for me.

Awesome food - in terms of both quality and quantity. I had been there for a few times - the quantity of their dish is 2~3 times more than what other restaurant around this area could offer. Yet taste of the food matches what I expect from a 4~5 star restaurant in Beijing. Sometimes I had to wait for a few minutes before their staff could get to me - maybe they need to hire more as they look very busy most of the times.
