  • 2 days ago · Hi all, I’m working on a model for multi-task learning which has, say, 1000 tasks. nn.ModuleList() was used to wrap those tasks (heads) as shown in the below model. Assuming the batch size is 32, the output is a list of 1000 sublists each has 32 predicted values. One issue here is the label matrix is actually very sparse (>99% sparsity). May be only 10 out of those 1000 sublists actually ...

PyTorch is an open source machine learning library for Python and is completely based on Torch. It is primarily used for applications such as natural language processing. PyTorch is developed by Facebook's artificial-intelligence research group along with Uber's "Pyro" software for the concept of in-built probabilistic programming.
