JPEG uses 8x8 blocks. But there's no reason we can't apply DCT to bigger sizes. It could be cool to make this changeable or just apply DCT on the whole...

Currently the slider "compresses" the image by zero-ing out DCT components in order of highest weight. This is not quite how JPEG works in practice. To apply compression, you divide...

Consider explaining LDA without "optimization"

1

It was suggested [on /r/statistics](https://www.reddit.com/r/statistics/comments/fiiq9n/e_a_geometric_intuition_for_linear_discriminant/fl711fk/?context=3) that thinking of LDA as an optimization problem as described in this article isn't how statisticians currently think about LDA. This would explain why it...

Something I completely skipped over is how to actually solve this optimization problem. Partially because I thought it was outside the scope, but also partially because I don't know it...

The article never explains why Fisher's formula has a denominator of (S1 + S2) as opposed to, say (S1 * S2). This is something I haven't been able to figure...

Th article says: > This particular metric is what Fisher chose, but it's certainly not the only possible one. A different metric could optimize for different results (perhaps you care...

First I wanted to say thank you very much for creating this! I whole-heartedly agree that comments often miss context and I really like the non-intrusive way you've implemented this....
