market cap = book value + discounted future cash flows = share price * number of outstanding shares When you do a buyback, the book value drops (company loses cash), but the discou…

There's nothing about PPO that helps it learn long-range strategies. It primarily lets you make multiple steps for a single batch so you can converge faster. In fact, for a single …

The author of that paper has since built an agent that has human-level reaction time and is comparable against professional players: http://youtube.com/vladfi1

People rarely train ML models on macOS for the reason you mentioned. Most machine learning work happens on Linux, so this should work well there. TensorFlow supports a standalone s…

Keep in mind that what you linked refers to TPUv1, which is built for quantized 8-bit inference. The TPUv2, which was announced in this blog post, is for general purpose training a…

An exponent bit flip, especially at later layers, would completely break inference.

Yeah, essentially a lot of supporting libraries were written in Python at first, and they need to be ported to C++ to make other languages train.

I'll discuss this a bit during my talk at the dev summit. The short answer is no. The long answer is yes, but only if you create the model in Python, export it, and then feed train…

(I agree that thread-per-request works just fine in the majority of cases, but it's still worthwhile to write about the cases where it doesn't work.) Responding to your original po…

It's not clear what you're suggesting as an alternative. My understanding is that you're suggesting thread-per-request, which has many known flaws. There are three approaches to se…

I think this is fair. Bandwidth costs money, usage likely follows a power law distribution, and their fees are reasonable: AT&T: $10/50 GB = 20 cents/GB Amazon S3/EC2: 10 cents/GB …

That would never happen. The problem is that Amazon has no operations in certain states to avoid charging sales tax. Buying Borders would put them in every state.

At least in economic theory, a company does not give out dividends if it believes that it can get a better return on its cash (in terms of profit) than the investor can in the over…

The article doesn't make it very clear, but Shiller's number is based on the average inflation-adjusted earnings of the previous 10 years. See the Excel file here: http://www.econ.…

It's possible to extract the address ranges, street names, city, and state using the TIGER/Line dataset. It won't give precise addresses (for example, if the range is 200-300 and a…

I'll link to your TrueSkill post for those who haven't read it (it's excellent): http://www.moserware.com/2010/03/computing-your-skill.html Although I already knew and understood T…

There are many obvious problems with this argument: 1. The 80% number seems to be pulled out of the air. It could be a counting error or a statistical aberration of that class, and…

Well, I mentioned this study to a friend, and he made a good point: The metric in the study is how many messages women send to men. If you're a taller woman, you likely will not me…

If you don't care too much about the theory and just want to get up and running, you should read: http://www.csie.ntu.edu.tw/~cjlin/papers/guide/guide.pdf And libsvm is probably th…

There are far better methods than the one linked in the article. You can train a covariance matrix such that you can get a better distance metric. Particularly, you would use the M…

Almost all of the fish oil you can buy actually comes from 1 company and have been tested for mercury (by ConsumerLab.com and Consumer Reports): http://www.usatoday.com/news/health…

If you have a statistics background, it's pretty easy to tell that it's significant given the numbers (2 of 41 in the fish oil group and 11 of 40 in the placebo). The exact p-value…

A white Y using a standard font on an orange background isn't a hugely original logo. It's quite conceivable that they came up with it themselves given the topic of the book.
