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 discounted future cash flows remains unchanged. The number of outs

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 step with no policy lag, it's equivalent to a stan

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 server mode where it receives computation graphs and executes

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 and uses 32-bit weights, activations, and gradients. It will

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 training data in other languages. There are some people doin

(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 post: you argue that async/await intends to sol

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 serving requests: 1. Thread-per-request. This i

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 It's not like we're being gouged here...

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 overall market. But, companies must eventually give out dividend

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 address 250 doesn't exist, it won't say that). It also isn'

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 the real Harvard number could revert to the mean. 2. The t

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 Mahalanobis Distance: http://en.wikipedia.org/wiki/Mahalano

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 is in the paper (0.007), or very significant. It's often d

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.

It's almost always better to teach the concrete and practical before the abstract. That's like teaching the rules of grammar before teaching them to read and write.

That's not completely true. Spending increases the velocity of money ( http://en.wikipedia.org/wiki/Velocity_of_money ) which can, in the short term, increase employment.
