An eigenvector is like a special arrow that, when you multiply it by a special number called an eigenvalue, it stays pointing in the same direction, but gets longer or shorter.

That’s completely wrong. It’s got the pieces of the concept there but mangled them in the final answer.

@joel Unfortunately Coursera has become hit or miss in recent years, at least in a couple of courses I tried a while ago. Some are quite worth the money and others not at all. I’ve heard other people complain the same way. I have no NLP background myself.

@wayne, I thought I’d replied to you yesterday, regarding Coursera, but I don’t see the text here. I started auditing the first class in the NLP specialization, as of two days ago. Coursera used to let people audit for free, but this course came up as a 7-day free trial. I’ll know in about 4 days whether they THEN allow you to continue to audit. I…[Read more]

@mike, I’m looking at the notes, and focused on them far more than ChatGPT. I was mainly curious about what CG’s capabilities were (in terms of the kind of output it could produce based on the content and structure of a question), and how I would need to ‘format’ questions, and how much detail I’d need to provide, in order to get accurate,…[Read more]

@joel, this kind of thing is not going to help you much. I hope you’re actually looking at the notes!

Thanks Mike! It is great to get back to thinking about this.

@joel

Generally python. Jupyter notebooks for testing.
Some Matlab for quick prototyping and testing sometimes.
Maple for analytical stuff.

My ‘product’ is processing of biomedical signals.

Have you looked at Coursera’s NLP offerings?

@wayne I’m just getting to the point where I can code in python. I’m curious what languages you code in, and what the ‘product’ is of your work. My main goal is to use python for math in general, but also for Open Source Intelligence (mainly for detecting and analyzing influence ops and disinformation campaigns; python’s NLP modules and…[Read more]

Deeper into the math itself (and python for quantum mechanics; one of my biggest problems right now is likely that I know so little of the math, and have such a limited ‘understanding’ of the concepts that the questions I ask might actually mislead ChatGPT into providing an irrelevant or inaccurate answer):

Thanks, Mike. I was working on it earlier today, and using ChatGPT occasionally to help me understand concepts:

Give me an overview of Bell’s non-locality theory, simple enough for a child to understand, then show me a list of essays and books, with links to each, that cover the topic.

Bell’s non-locality theory is a scientific idea that helps…[Read more]

@joel, see if you can get it to do the homework for March 5th (i.e., work the Bell State problems). Or for that matter any of the stuff leading up to that. And maybe it can tell you something about either “GHZ States” or “Hardy States” (you might add in nonlocality as a keyword).

This is really helpful.

For the coders among us, here’s an interesting Medium article on leveraging ChatGPT in software development.

Note that the links I asked for aren’t present in the answer. ChatGPT does this fairly consistently, with regard to ignoring a request for links. It might be a legal issue (to avoid a lawsuit for directing a massive amount of traffic to a site? Wild guess). Or it could be just a way to conserve computational power, since ChatGPT has (according to…[Read more]

In my opinion, ChatGPT didn’t give you very good advice. Either with the time allotted or the resources it suggested. But the topics to be studied weren’t too bad. It looks like it mostly just copied an outline from the MIT website.

In case anyone is going to attempt the Bell State problems, here are the 45 degree (one bit) basis vectors:

The 45 degree operator is:

It’s eigenvectors are:…[Read more]
