Originally I was using ML.NET (the standard dot net machine learning library), but I didn't know what I was doing so I decided rolling my own would be a good way to learn. I understand the intuition well enough now that I could go back to it, but I'm committed to getting it right now. Plus it's just a personal project, so time's not an issue.
Thank you!

Apologies if this isn't an appropriate place to post this.
Inspired by a paper I found a while back (https://publications.lib.chalmers.se/records/fulltext/215545/local_215545.pdf), I tried my hand at implementing a program (in C#) to create ASCII art from an image. It works pretty well, but like they observed in the paper, it's pretty slow to compare every tile to 90-some glyphs. In the paper, they make a decision tree to replicate this process at a faster speed.
Recently, I revisited this. I thought I'd try making a neural net, since I found the idea interesting. I've watched some videos on neural nets, and refreshed myself on my linear algebra, and I think I've gotten pretty close. That said, I feel like there's something I'm missing (especially given the fact that the loss isn't really decreasing). I think my problem is specifically during backpropagation.
Here is a link to the TrainAsync method in GitHub: https://github.com/bendstein/ImageToASCII/blob/1c2e2260f5d4cfb45443fac8737566141f5eff6e/LibI2A/Converter/NNConverter.cs#L164C59-L164C69. The forward and backward propagation methods are below it.
If anyone can give me any feedback or advice on what I might be missing, I'd really appreciate it.

And the four GameCube controller ports are actually headphone jacks that work over a special adapter. Smith made these headphone-to-GameCube dongles pin-compatible with an earlier mod called the GC Nano, a project that did for the GameCube what the Short Stack does for the Wii.

and capitalists as not a cabal of power directing the experiences of the other groups.
I'm going to give you the benefit of the doubt and assume you didn't do this intentionally, but I wanted to point out that the term 'cabal' is an antisemitic dog-whistle, and is often used to imply that 'the jews control everything' without outright stating it (https://www.ajc.org/translatehate/cabal). It's very possible to know/use the word without knowing this connotation, so I'm not saying that was your implication, but it's good to know the history behind the word at least.

First was hbomberguy's plagiarism video from a few weeks ago, then I started watching his other videos. Then Jenny Nicholson popped up so I started watching her as well. Both long video essay channels, so I guess Folding Ideas is next on the list.

The parallels he draws between these games which seemingly lack any deeper meaning, and imperialism is very interesting—partially since now that he's pointed it out it's obvious, but I otherwise never would have made that connection. It's the same problem I struggled with when we had to do literary criticisms back in high school. It's very easy to consume a piece of media without thinking about themes and underlying meaning (whether intentional by the creator of the media or not).

Comment on The old games that still hold up incredibly well in ~games

I play the Enhanced Editions of Baldur's Gate now, which are newer, but the originals still hold up as well. Planescape Torment holds up well too, and I think that got an Enhanced Edition recently. Fallout 1 and 2 are also good choices.
Gameplay-wise, they're all great, but graphically you can definitely see their age.

Comment on Have mass migrations ever happened for positive reasons instead of because hardship or lack of opportunity in their home countries? in ~talk
a_sharp_soprano_sax Link ParentYour answer also reminded me of the Homestead Act, where the US encouraged settlement of the west by promising free plots of land. Not sure if that qualifies as mass migration, though.Your answer also reminded me of the Homestead Act, where the US encouraged settlement of the west by promising free plots of land.

If you're willing to play in a star wars setting, Star Wars Knights of the Old Republic 1 and 2 have dnd style gameplay and are probably 2 of my favorite games. In a more typical fantasy setting, Pillars of Eternity, Pathfinder Kingmaker and Pathfinder Wrath of the Righteous are all fantastic dnd/pathfinder style games as well. You could also go for Divinity Original Sin 2; gameplay wise it strays a bit from the above examples but it is still a great game.

I do have some contact-safe rewetting drops that I haven't really used much, maybe I'll try using them more frequently and see if that makes a difference. I'd really like to be able to wear contacts instead of my glasses so I hope it's not a matter of my body just rejecting them. Thank you!

Hi, I started trialing contact lenses (toric lenses, specifically) about a month ago, and have had a problem with them making my eyes seriously red. I've tried 3 different brands of contacts now, and the issue has persisted across all three. Has anyone else had a similar experience and figure out how to manage it? Thank you!

Don't think I see anyone mentioning Science Asylum. Some physics videos that I found enjoyable and digestible. They're pretty high-level and don't get too much into the math or anything, but still good at communicating the concepts.
