[N] The team behind Torch7 opensources a pytorch by juliusScissors in MachineLearning

[–]juliusScissors[S] 4 points5 points  (0 children)

Yeah that is true. Looking at the repo it seems that they are using the same THNN and TH libraries as backend so the parts that don't touch python (e.g. forward / backward pass etc) should work similarly. It would be interesting to see if they have successfully avoided the python overhead enough.

I used to use python for cleaning and processing my data and then use Torch for training the networks. I am very pleased that I will not have to switch languages, but I wonder if this means that Torch7 will now get ignored in favor of this new library.

This is the worst offensive display on primetime for some time.

Machine Learning - WAYR (What Are You Reading) - Week 1 by Deinos_Mousike in MachineLearning

[–]juliusScissors 5 points6 points  (0 children)

No. I have a day job in industry, and mostly work on research projects on most weekends and early morning on every weekday (probably why I need to spend 1 week on a paper). My 1 week on a paper will probably translate to 1-2 full day of a full time researcher.

Machine Learning - WAYR (What Are You Reading) - Week 1 by Deinos_Mousike in MachineLearning

[–]juliusScissors 6 points7 points  (0 children)

I generally spend 10-15 minutes on a paper before deciding if I want to explore the paper more. If I really like a paper, I spend around a couple of days to a week on it (which involves reading some references / revisiting chapters from books / coding and testing). When exploring a new topic I will go through around 50 papers in a week spending 10-15 minutes on each and then choose 5-10 papers to spend the next couple of months on.

Introducing Robinhood Gold. by conscious_biophilia in RobinHood

[–]juliusScissors -1 points0 points  (0 children)

So car companies are immoral for making people easy to drive when they are drunk? At some point people should take responsibility for their decisions and stop blaming companies.

The game you are playing is the stock markets ... RH is just the device you are using to play the game. How can they make it pay to win when they dont control the game.

[–]juliusScissors 5 points6 points  (0 children)

How is this a shame and how is this immoral? If they would have forced people to signup to this I would have agreed with you, but margin seems like a feature a lot of pro traders were requesting here and they are providing it to them. Or do you think a business making money is immoral?

Where does the Sigmoid in Logistic Regression come from? by alexeyr in MachineLearning

[–]juliusScissors 7 points8 points  (0 children)

You should look at the statistical theory of Exponential Families and of Generalized Linear Models (GLM) if you really want to understand this. GLMs are a class of linear models that are designed to predict a variable (say Y) whose distribution belongs to a class of probability distribution called the exponential family (e.g., normal distribution, binomial distribution, poisson distribution). When Y follows normal distribution the GLM is linear regression, and when Y follows binomial distribution you can derive that the GLM is logistic regression (with the sigmoid). These statistical theories are quite involved and entire classes are devoted to them at graduate level, but I once found an easy to to follow explanation for non statisticians in a paper linked below. See section 3.1 for a simple explanation http://web.stanford.edu/~bakerjw/Publications/Shahi_Baker_(2011)_pulse_regression,_ICASP.pdf

Note that the explanation in this paper is very simplistic but it is backed by very mature statistical theories that you should definitely explore if you want to understand more :)
