Same issue with Safari. Ignoring that small issue, this is a well-crafted and mature resource, one I wish I had access to 5 years ago! Good job to the authors.

Sure the network effect is strong but let’s not forget how WhatsApp got here in the first place: people installing a strange new app, often shared by their friends via a text message invite link. I remember sitting in a circle with a group

It may have “little to no value” for some, but to others, perhaps many, there is plenty of value. Why else would famous fashion designers and the entire fashion industry be worth so much? It’s easy to overlook the value but from a basic and

I was confused the first time I saw this in the US. Thanks for sharing the video, but nonetheless I’m still surprised that something as common sense as amber vs red lights for different functions is still something US-bound models fail to a

Wow those diagrams are extremely well thought out and clear to understand. Saying they’re just blue boxes is a huge understatement. Visualising highly conceptual topics like numerical programming is not an easy skill, and the more the bette

I agreed that it’s better than the alternative. Also the alternative has the risk of amplifying echo chamber viewpoints. And then there is the fundamental of how new would comments break the barrier of getting upvoted in the first place?

It’s more than a bit creepy how Twinkly actively show locations of where setups have been mapped around the world, and even creepier that they show the time of the last device mapped. Sure it might be innocuous but are there other things th

But are machine learning models not statistical models? There is sample data which is statistics, and the objective function is also statistics, eg mean square error or negative log-likelihood or ELBO. And if you’re using stochastic gradien

Other comments point out to Bayesian inference being good for modelling an uncertain outcome, while deep learning is good for prediction. However Bayesian inference is a good choice for prediction when you have few data points (deep learnin

Please no, we don’t need Stan to be rebuilt with a Python backend. That it’s built in C++ and can be called with higher level API’s is part of the appeal.

This really became vivid for me the last time I visited the Kruger National Park in South Africa. I was in a wooden hide overlooking a small lake, and was lucky enough to witness a herd of about 20-30 elephants emerge from the bush on the o
