Cool, I worked on indoor localization, particularly with RTT, at Google for many years :)

Maybe we can get in touch, I am curious to have a more senior perspective on the indoor localization!

I took "Mathematical Methods for Quantitative Finance" from edX, which covered these topics, and found it really rewarding.

Same!

From the wiki article:

> Scholars believe that the Novgorod Republic had an unusually high level of literacy for the time, with literacy apparently widespread throughout different classes and among both sexes.

I read that too and I was surprised, but then the first thing that popped into my mind was that this is probably a case of survivorship bias

Ah, I missed that important bit.

I bought my father a RM-BIV3 ribbon microphone [0] to record violin. It's a beautiful piece.

To bring things full circle: the cross-entropy loss is the KL divergence. So intuitively, when you're minimizing cross-entropy loss, you're trying to minimize the "divergence" between the true distribution and your model distribution.

This intuition really helped me understand CE loss.

Cross-entropy is not the KL divergence. There is an additional term in cross-entropy which is the entropy of the data distribution (i.e., independent of the model). So, you're right in that minimizing one is equivalent to minimizing the other.

Yes, you are totally correct, but I believe this term is omitted from the cross-entropy loss function that is used in machine learning? Because it is a constant which does not contribute to the optimization.

Please correct me if I'm wrong.

Increasing efficiency often causes an increase in consumption, not less [0]

Except for when it doesn't. E.g. lightbulbs are now 20x more efficient than in my childhoos. But I certainly don't use >20x more light(bulbs). In fact, I'm quite sure it's 1x.

You probably have LEDs in everything though.

I was concussed and suffered from persistent headaches for 2 years.

It was really tough. I was suicidal. My only reprieve from pain was falling asleep.

I saw a neurologist and he told me that two most important things for your brain are:

- consistent sleep schedule

- regular exercise

Once I got those two under control, the headaches finally went away.

The Vice documentary mentioned in the article is really great [0].

Best of luck to Agafia.

I exploited one of these regional naming conventions so that I only have a first name on Facebook.
