## Tensorflow

### Tensorflow custom cost functions with different weights

- Is there a way in Keras to apply different weights to a cost function? · Issue #2115 · keras-team/keras is a really nice discussion with options, especially the latter part of it.

### Tensorflow F-score / PR

- How to calculate F1 Macro in Keras? - Stack Overflow is a nice F1 / PR implementation that works as custom metric
