What does "backprop" mean? Is the "backprop" term basically the same as "backpropagation" or does it have a different meaning?
Welcome to Artificial Intelligence Stack Exchange
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.
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.
What is "backprop"?
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.
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
- Recommendations for career paths, development tools, datasets or pre-trained models
- Multiple problems
