Description
A new abstract device that implements an SGD optimizer that does not do the update step in fully analog mode, but instead computes the outer product in digital (assuming a high precision storage of the result) and then transfers it to the analog tile. For details, see Nandakumar et al. (2020) https://doi.org/10.3389/fnins.2020.00406
Details
To use this tile, one specifies it in the
rpu_config, e.g.Presets are available as well. The mixed precision compound also supports quantization of activation and error as well as sequential transfer to the analog tile.
