Creating new layer FCWithBootstrap used in bootstrapping uncertainty approach (#29152)
Summary:
Pull Request resolved: https://github.com/pytorch/pytorch/pull/29152
Bootstrapping uncertainty approach: bootstrap the last layer before the last fully-connected layer. FCWithBootstrap is a new layer to handle the logic for the bootstrapping process.
Goal:
- return a struct with the bootstrapped indices and bootstrapped predictions from this layer
- separate the functionality in the train_net and eval_net
- save the bootstrapped FC in this object so that the eval_net can use them during prediction time
