I'd like to request career advice for those in data science, machine learning and artificial intelligence. You may assume top pedigree, but generalizable advice is also appreciated…

I went from barely using data.table to only using data.table for basically everything in less than a few years. I think this is the trend given it's faster than basically everythin…

The way I use Python in machine learning is quite different from how many others in competitive ML use Python. I use Python purely for Python 2.7 with Pypy and try not to touch or …

It is a fact that students at top tech schools (think Caltech, MIT, Harvey Mudd, etc.) study longer compared to students at comparable liberal arts schools. I believe it takes time…

I wish academics would publish pure python implementations of their "new" algorithms. Standard python with Pypy is enough for speed of development and runtime. The biggest thing ab…

I would not be surprised if most academic CS research is not reproducible. This is true for many other fields outside of CS, and I've seen it first hand in machine learning. It's a…

I know people who work at those research divisions (they work with neural networks) without a PhD. So I just falsified your claim.

This is incorrect in almost every way. When you have 2^m independent observations that you can use to cross validate (where m is very large), overfitting is exceptionally difficult…

This is supposed to be faster than XGBoost? I'm skeptical, but I'd like to know the specifics of the benchmarks and maybe an outline of the code / reasons why. It was not benchmark…

If people would just learn to resample (cross validate, use subsampling or the bootstrap), we wouldn't be having this pointless discussion at all.

I'd like feedback on if this algorithm is new or has been published before. I think it's new, but I've been wrong before on these types of issues. Thanks: Mike.

You wouldn't find it intuitive if your first language was Scheme.

Pypy is actually much faster than both standard Python 2.7 and R in basically everything requiring the standard library.

This might even be useful when applied to learning say data.table or other parts of the Hadleyverse. These days data.table is not an option given the size of data and how slow R da…

You could just use data, machine learning and optimal control to make better estimates. It has aleady worked for fighter jets, self driving cars, and automated factories. With enou…

Tommy Kono would disagree with you. Albeit he was a weightlifter.

it is probably easier to just wrap R functions as a subprocess in python. you would have to write some R code to do this which might involve writing to a flat file. i do this all t…

As long as you make the public leaderboard set small, and the private one shot leaderboard set very large, the number of submissions matters very little in the final rankings. The …

so you mean there are 5 entries you can select to be scored in the end, and there is one private leaderboard no one can see but the admins? do you know the size of the private lead…

Is there a private one shot hold out in this particular competition?
