Contributions summary:Peter's primary contribution centers around enhancing the Swift for TensorFlow deep learning library. They implemented and tested differentiable versions of core tensor operations like `product` and `reversed`, enabling automatic differentiation within the library. Furthermore, the user added and refined tests for recurrent neural network (RNN) layers, including tests for GRU and bidirectional RNNs with various merge modes, using reference implementations. Their work significantly expanded the library's capabilities for training and differentiating deep learning models written in Swift.
