xrange() is deprecated in Python 3.x. consider using range() instead.
In line 119: Before: because that it is how many neurons After: because that is how many neurons
inaccuracy regarding hierarchical softmax. This pull request fixes it by clarifying the use cases of hierarchical softmax.
Fix in NN2 lecture notes
Corrected the loss function of logistic regression. Added the missing negative sign and also a short comment on the loss function (i.e the loss function of logistic regression minimizes the negative-log likelihood)
Fixed bug in variance calculation at the second step. See https://en.wikipedia.org/wiki/Variance#Product_of_independent_variables. Co-authored-by: mli0603 <lizhaoshuo12345@126.com>
The linear classification notes linked to an interactive demo at:
http://vision.stanford.edu/teaching/cs231n/linear-classify-demo
which is now a dead URL. The demo was later moved to:
http://vision.stanford.edu/teaching/cs231n-demos/linear-classify/
This commit embeds the demo directly in the repository under:
assets/linear-classify-demo/
mirroring the existing pattern used by:
assets/conv-demo/
Demo source attribution / original URL:
http://vision.stanford.edu/teaching/cs231n-demos/linear-classify/
The now dead link was last updated in commit ed95fdf
This avoids issues with future broken external URLs as the demo is self-contained within the repo.
And by version controlling the demo, future contributions can be made to the demo itself.
The link in linear-classify.md is updated to a relative path so it remains valid regardless of hosting.
Changes to the original demo source have been kept minimal:
- MathJax CDN: http://cdn.mathjax.org/mathjax/latest/MathJax.js
changed to https://cdnjs.cloudflare.com/ajax/libs/mathjax/2.7.1/MathJax.js
(cdn.mathjax.org was shut down and no longer resolves)
- Google Fonts: http:// upgraded to https://
All other source code is unchanged from the original. e.g.
```
$ wget -qO- "http://vision.stanford.edu/teaching/cs231n-demos/linear-classify/" | diff - assets/linear-classify-demo/index.html
