I work as an applied mathematician writing numerical codes and I prefer to prototype in MATLAB/Octave for a number of reasons: 1. I believe it to be far easier to debug an algorithm in MATLAB/Octave than Python. When I drop into

Sort of. Depending on the clearance issued, there are a number of requirements that endure even beyond the duration of clearance. Most of the time, this just applies to work related material. However, certain clearance levels require tha

I skimmed the article and I enjoyed it. Recently, I was looking for a good reference to cite that discussed the link between automatic differentiation and back propagation. From those I know if the field, they knew about the link for a ve

There's more information here: https://github.com/conal/talk-2018-essence-of-ad That said, has anyone had a look at the paper? What I can't figure out is the assertion that, "In contrast to commonly use

It's not and I also find it a bit frustrating when the default answer is just chain rule. For me, the key insights into how AD is derived are the following: 1. There is a fundamental difference between normed spaces and inner product

Backpropagation is literally the reverse mode AD applied to neural nets. That said, I wish had a paper that I could point to that shows explicitly that. From what I can tell, the AD community has known this basically since the start, but

Alright, this looks neat, but I'm having a terrible time figuring out what's going on with the benchmark. Typically for AD, it's easiest to see four things: number of variables, time to compute function directly with no AD,

To clarify, your statement that, "It uses a special sort of invented numbers which square to zero even though they are not themselves zero." is not entirely true. In case someone else is looking at this, what the OP is referring

I'm sorry your family member went through this. That's terrible and no one should have to deal with that kind of treatment. I'll echo much of what you said. When I was 21, I was diagnosed and treated for malignant melanoma

I like this, but I'll also contend that it's part of a broader question in applied math: What does it mean to be zero? One way to define this is to say that a vector is zero when it's orthogonal to every other vector in some

Since you made a mention of CMake, does Rust really provide an alternative for building multilanguage projects? When I went to look for examples on how this is managed, it seemed horrendous. For example, some projects manage this by writi

Will that be FIDO2 compliant? I was under the impression that it's using the older standard that does not allow a per-account identifier to be stored on the device: https://www.yubico.com/2018/05/what-is-fido

Some of the other posts have already picked up that this doesn't appear to do U2F. Along that line, does anyone know if there are any new FIDO2 compliant keys are the market is is still just Yubikey? Are more sites adopting Webauthn

Mostly, I'd like to ensure that I don't like the dll, so that I don't have to attempt to distribute it. More selfishly, I'd like to have a straightforward installation process where I pull down only a binary or two and

No it's not. I've seen it used within petrochem and other engineering firms as well. For example, the real time simulator Opal-RT uses Simulink and Opals are used for things like simulating power systems. Although you may not li

I've thought about it and wrote a bunch of trial software to test things. Primarily, I work on Linux even though I support Windows. There are also some features in OCaml that I like, which are not available on F# such as the module s

What's the current state of OCaml on Windows? I'd love to use OCaml on more of my projects, but this has been a roadblock for me. What I'm looking for is the ability to produce native binaries without Cygwin. I just checked

Could someone explain the difference between FIDO and FIDO2 compliant keys? For example, is new hardware required or will existing FIDO/U2F keys work with FIDO2? It looks like Yubico is advertising a new FIDO2 key under the brand nam

Awhile back, I was looking at using a TREZOR as a U2F key. I liked it since the interface looked good, confirmation of sending the key on the device itself, and the software was open source. For those two reasons, it looked nicer than usi

Technically, you need neither. Branch and bound works by solving a series of relaxations with fixed integer variables in order to better search the discrete space. Now, imagine we're solving a minimization problem. Finding a feasibl
