@mhoye @gabrielesvelto @rmflight If this works out well we'll see better + smaller models for all tasks (not just classification) that outperform both current DNNs and the NCD technique they use at moderate cost. There's precedent of this being a successful approach for example using frequency domain data for audio models instead of raw PCM. There's also precedent for finding ways DNNs waste a lot of capacity on effectively routing data around and restructuring to fix (ResNets for example).
