Welcome to Artificial Intelligence Stack Exchange

site icon

Artificial Intelligence Stack Exchange is a question and answer site for people interested in the theoretical (including mathematical), philosophical, social, historical, and certain developmental and academic aspects of artificial intelligence.

It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about artificial intelligence.

We're a little bit different from other sites. Here's how:


Ask questions, get answers, no distractions

This site is all about getting answers. It's not a discussion forum. There's no chit-chat.

Just questions...

...and answers.

Good answers are voted up and rise to the top.

The best answers show up first so that they are always easy to find.

The person who asked can mark one answer as "accepted".

Accepting doesn't mean it's the best answer, it just means that it worked for the person who asked.

It's a fancy name for the multivariable chain rule.

"Backprop" is the same as "backpropagation": it's just a shorter way to say it. It is sometimes abbreviated as "BP".


Get answers to practical, detailed questions

Focus on questions about an actual problem you have faced. Include details about what you have tried and exactly what you are trying to do.

Ask about...

  • Theoretical
  • Philosophical
  • Social
  • Historical

aspects of artificial intelligence

Not all questions work well in our format. Avoid questions that are primarily opinion-based, or that are likely to generate discussion rather than answers.

Questions that need improvement may be closed until someone fixes them.

Don't ask about...

  • Anything that is not directly related to artificial intelligence
  • Programming issues and bugs
  • Opinions
  • Recommendations for career paths, development tools, datasets or pre-trained models
  • Multiple problems

Tags make it easy to find interesting questions

All questions are tagged with their subject areas. Each can have up to 5 tags, since a question might be related to several subjects.

Click any tag to see a list of questions with that tag, or go to the tag list to browse for topics that interest you.

Hello. Could you support this answer with a little more detail? (I realize it's a simple question, but I think your answer is worthy of greater explication.) - DukeZhou Apr 23, 2020 at 21:06
