I haven't read this paper yet so I can't speak to it's quality but it appears to be addressing the same questions in this post. Bengio is a coauthor so maybe that's a good sign . Here's the abstract. This paper prov

The problem is high dimensions knowing the distribution or even characterizing it fully with data is incredibly difficult (curse of dimensionality). I think the real assumption in ML is just that there is some low dimensional space that cha

Julia only hit v1.0 in 2018. It's doing pretty well for being so young in my opinion. All the arguments against Julia are basically that python has a lot of momentum and it takes time and effort to switch to a new language. I think Jul

SAR has been around since the 70s and works using the same principles as CT scans (projection slice theorem). Think about observing an image by rotating it and projecting it orthogonally to the rotated direction. Take a bunch of these measu

Typically when you downdsample you're going to want to filter than use whatever downdsample kernel you want with the correct stride. Since the filter is lowpass, think just Fourier transform then taking an inner smaller square of the i

I think this suffices as a summary, "The other reality is the frustration and drudgery of operating in a world of corporate politics, bureaucracy, envy and greed— a world so depressing, that many people quit in frustration, never to co

I was expecting this to be more about writing fast matrix multiplies. Surprisingly, it ends up being a lot more than just a triple loop and there's a reason that everyone uses existing libraries like OpenBLAS and MKL [1]. [1] https:&#

I think this is really the tale of two Millennials and is a phenomenon that actually effects all generations currently. There is a concentration of wealth in this country and the wage increases in the bottom 90% have not kept up with the co

This article may have been on here yesterday and seems relevant [1]. For this guy it's probably not about fighting for what he believes is "right", it's all about winning. He bought land, a fight ensued, and now he relis

The author does make a point of discussing the question of what business does a team like DeepMind have researching the folding problem? The solution is of no apparent value to the parent company Alphabet, and yet they were still funded. Pe

Isn't there utility in accepting the null hypothesis? It's almost as valuable to know that there is no signal in the data as there is in the opposite, i.e., knowing where not to look for information. I think your example is really

I used to only use MATLAB, which for a lot of research code applications is actually nice for getting a prototype running quickly. Now that I have the freedom to choose, I typically use Julia as I'm trying to gain skills in opensource

Looks pretty nice. Unfortunately, I never run into this issue because I only get to write research code. The Julia language was designed to target the two language problem and at least from these benchmarks it looks pretty competitive [1].

All good points. It would be nice to see some game theory type assessment of these imbalances.

So he's saying that concentration of "wealth" is bad, and war is bad. A quick glance at the definition of moral gives, "a person's standards of behavior or beliefs concerning what is and is not acceptable for them t

These types of experiments pop up from time to time. You have to compare the performance relative to the single lag error. So the baseline is to use the previous time step to predict the current time step. Ultimately, it's not worthwhi

This latest craze of "AI" research seems to be fueled by a sudden glut of computational power (GPUs) that wasn't available previously. I think that most technical people would agree that the mid 2020s is extremely ambitious.

I wasn't implying that the interview was easier for candidates with recognizable track records. Perhaps two sigma was not restrictive enough. I was merely suggesting that if a candidate has domain expertise and it is well known, that t

All anecdotal evidence points to arriving at the correct, optimal solution as being key to passing the interview. It also seems like often times the interviewers are not even going to be working with the candidate so their opinion on a &#x2

As a fan of technical death metal and a guitarist it is one of the few genres that has the depth and complexity to keep me interested. This is also why I enjoy music from Sibelius and other classical greats. In contrast, most pop music is s

But your estimate isn't very meaningful if you only have enough samples such that the N v (N-1) normalization matters, the variances on the estimator will be too large. The 1/N normalization comes from the MLE BTW, I'm sure m

Seems to me that at some point hiring moved away from hiring based on potential to hiring based on pure skill and how many boxes the candidate has checked. Companies seem to just want people who can turn the crank, which doesn't sound

Why penalize folks who didn't know what they wanted to do in high school. It took me a long time to get a vague idea of what I wanted to do for a career and it's something I have to constantly contend with. In fact, I'm still
