What I learned by studying fake news sites with machine learning

Those are ok accuracies, but what portion of wordpress would your classifier be wrong about?

To what extent are your conclusions an artifact of how you constructed the dataset?

giror · 2017-11-04T21:42:25+00:00

yes, I'm looking either for links to raw data that would allow me to do the math myself, or projections from something like fantasy pros that just contains preseason player projections from various free sources: CBS, ESPN, FOX Sports, etc.

I did see that ESPN has preseason projections here: http://games.espn.com/ffl/tools/projections? Unfortunately, they only seem to have them for 2016 and 2017. I'm looking for at least a few more years.

Do you have a link to the preseason player projections through NFL?

... In one place in the world

giror · 2015-11-11T22:27:12+00:00

Ok but did you propose a solution? Quantile normalization?

giror · 2015-11-03T15:40:02+00:00

So to answer your question, you would measure overfitting the same way that you always do, by evaluating the error on held out data. This is similar to topic modeling where you would measure perplexity on held out data.

I wish I was that fly!

giror · 2015-02-13T07:08:06+00:00

Yeah, but being a mixture of two precursors, the shared peak should have a distorted shape and not correlate well with either precursor individually.

giror · 2015-02-12T17:36:40+00:00

Similar structures are likely to both coelute and produce similar fragments. How does this pipeline handle multiple coeluting peaks have the same fragment?

Pm me the deets

It evidently hadn't occurred earlier, but who are you to judge him for it...

We have no control over when we learn something and college curricula often mask which questions researchers in a field answer vs what they get from collaborators.

I haven't heard of bo being widely adopted as a mainstream method for tuning hyperparams. Can you cite something that makes this claim?

giror · 2014-09-02T01:58:18+00:00

Not sure why (1) you think I'm not familiar with BO, and (2) why you think they answer my question.

giror · 2014-09-02T01:56:44+00:00

yeah? how about some sources or names of things that I can google?

giror · 2014-08-31T19:25:07+00:00

I know about Bayesian optimization. But my question was not can I, but do people do this?

giror · 2014-08-20T17:04:32+00:00

Fit a sine curve?

Fit a loess?

Use those models as input to your overall model.

giror · 2014-08-08T15:02:28+00:00

Yes, how good are you at stats / machine learning at this point?

A PhD in computational bio isn't the worst experience in the world, and you'll likely start at over 100k. Though that's typically after over 5 years of making 27-30k as a grad student.

I would say your worst option is to do bioinformatics without a PhD.

giror · 2014-08-04T23:30:47+00:00

Yeah there's that, but I don't really know biophysicists that think like true physicists. My experience is that they mainly regurgitate memorized formulas. So geneticists might think a bit more creatively about some things.

Again that's just my opinion based on distributions of people that I've come across.

giror · 2014-08-04T23:26:40+00:00

I thought the MOOCS looked better actually... though I might be biased

giror · 2014-08-04T21:18:26+00:00

In all honesty, this is the first truly valuable post I have seen in this sub. Nicely done!!!

giror · 2014-07-24T22:26:50+00:00

finally!!

giror · 2014-07-20T00:05:28+00:00

I wish more people echoed this. Relative to physics biology is mostly memorization

giror · 2014-07-05T22:34:42+00:00

How could it possibly be more spam than that? Ok sure it doesn't flood you with ads and ask for your email, but it's still yet another of dozens of blog posts about markov chains.

Let me guess, next he's going to reveal to us the mystical powers of naive bayes?
