+
+Our implementation is based on [this paper](https://arxiv.org/abs/1901.02731).
+
+### Layer type
+
+* **BBB_LRT (Bayes by Backprop w/ Local Reparametrization Trick):**  
+  This layer combines Bayes by Backprop with local reparametrization trick from [this paper](https://arxiv.org/abs/1506.02557). 
+  This trick makes it possible to directly sample from the distribution over activations.
