WolframAlpha + student licence is comparable for some tasks, I've found (hard integrals from applied probability theory).

This is a crucial point. There's a good chance these are problems that could be solved with more data. However, I think philosophically the challenge of integrating these models in a modern healthcare system is more fundamentally relat

This is really interesting! I had always just claimed that Python was faster (see the benchmark I linked above [1]) based on personal experience. I wonder if this internal implementation has something to do with it... [1] https:/&#x2F

Speed. [1] See the yellow benchmark (matrix multiply). I suspect it's memory-related. [1] https://julialang.org/benchmarks/

> Not an advantage if you ask me - exactly because data.frame is built in, people have been building their own versions (tibble, data.table) instead of improving it. That's how R ended up with 3 different structures that are similar

I agree for the most part, but R does have a few things beyond the tidyverse: built-in dataframe support, lots of domain-specific packages, more consistent interfaces for basic statistics and machine learning models, etc. Python is definite

Surely an entity such as the EU could go so far as to ban the sale of bunker oil to passenger cruise lines with offices in the EU, or something to that effect?

It almost certainly is. Likewise for the dye.

From a machine learning standpoint, I would guess that this is achieved with a partially supervised approach. The idea would be to embed an entire face dataset from a number of different poses to a latent space by some method (could be as s

True, it's not a perfect system. But that would likely not be the case for a vaccination database, anyway.

It seems like vaccination info is not kept at the state or federal level. This information is no doubt extremely dangerous - imagine if a malicious actor could get ahold of the "non-vaccinated list." But right now, it's store

Yes. This problem is of particular importance in drug response prediction, where small molecules are represented as graphs where the atoms are nodes and the bonds are edges. These are difficult to work with because of the variability in the

I think it's highly task-specific. In network biology for example, taking advantage of the network structure, either through node embeddings or directly, is almost always helpful (even necessary). I'm not as familiar with applicat

Variational graph auto-encoders, also by Kipf and Welling, is another great short, understandable paper. [1] [1] https://arxiv.org/abs/1611.07308

Check out UMAP [1]. It's an alternative to t-SNE for dimension reduction that's grounded in topological category theory. [1] https://arxiv.org/abs/1802.03426

OK, but that's not a problem with NVC. "You are sloppy" is an evaluation. An observation would be "the reports you produce consistently have errors" or something like that.

Well, fundamentally, neurogenesis is just another form of cell division. The most well known disease of cell overproliferation is cancer. Most brain cancers are of the glial cells (i.e. not neurons, but their support cells). There are some

Interesting that you chose statistics as your example. I've always considered statistics to be the one branch of math I've studied where intuition keeps pace with depth and rigour. The caveat being that I am by definition an amate

So, let me make sure I have this right: 1. Fecal transplants are pseudoscience, because we don't know if they work. 2. We should assume they work, and identify specific microbes within them that are relevant or dangerous. That's c

R is nice for stats stuff, even if performance can be iffy for certain tasks. The existing libraries for basic ML tasks are largely fantastic. The syntax rubs many people (including me) the wrong way. But I don't like the paradigm for

I like that analogy. An even better one: porting the code of `sed' to a new operating system without fully understanding it, using `sed' to automatically correct bugs in fundamental operating system code without checks, recompilin

Well, I took it to mean PGP vs IronChat. I'll take an open source implementation of a well-established protocol over a closed source implementation of another well-established protocol any day.

Just because fascism and "communism" (as in, communism as implemented in China or the USSR) were at odds in the mid-20th century, doesn't mean they're incompatible.

I think it's important to be careful with the vocabulary here (if only because of the site we're on). There can be metrics that are targets which still remain good metrics. For example, in many machine learning competitions, the s
