pytorch-adaptive-computation-time
This library implements PyTorch modules for recurrent neural networks that can learn to execute variable-time algorithms, as presented in Adaptive Computation Time for Recurrent Neural Networks (Graves 2016). These models can learn patterns requiring varying amounts of computation for a fixed-size input, which is difficult or impossible for traditional neural networks. The library aims to be clean, idiomatic, and extensible, offering a similar interface to PyTorch’s builtin recurrent modules.
The main features are:
- A nearly drop-in replacement for torch.nn.RNN- and torch.nn.RNNCell-style RNNs, but with the power of variable computation time.
- A wrapper which adds adaptive computation time to any RNNCell.
- Data generators, configs, and training scripts to reproduce experiments from the paper.
Example
Vanilla PyTorch GRU:
rnn = torch.nn.GRU(64, 128, num_layers=2)
output, hidden = rnn(inputs, initial_hidden)
GRU with adaptive computation time:
rnn = models.AdaptiveGRU(64, 128, num_layers=2, time_penalty=1e-3)
output, hidden, ponder_cost = rnn(inputs, initial_hidden)
