v1.1.0

Changed

• Replace sync.Cond with a close of channel in the broadcasting mechanism of autograd ag package
• Refactor Matrix interface to extend from Tensor
• Replace ag.Node and ag.DualValue with mat.Tensor
• Breaking change: New single NewDense function accepting functional options (WithShape, WithBacking, WithGrad)
• Refactor BaseParam struct to embed mat.Matrix
• Remove Variable and enable gradient accumulation in Matrix
• Revise backward method and eliminate truncated backpropagation
• Backward function to require explicit output gradients to be accumulated beforehand
• Move package fn out of package ag and rename it to gradfn as mat subpackage

Removed

• Remove the parameter name to simplify the code and reduce unnecessary complexity (e.g., Introspect())
• Remove concurrent matrix-vector multiplication as it requires more careful considerations
• Remove the export feature in dot format
• Remove "spago" tag annotations on embeddings
