The FBTriton forward pass gathers vectors from the embedding table according to sparse indices and aggregates them along the sample dimension, and the backward pass scatters upstream gradients back to the embedding rows that were looked up, accumulating when the same row is hit multiple times.

UnverifiedThe binding operation in FHRR corresponds to complex multiplication, i.e., addition of phase angles; the unbinding operation corresponds to subtraction of phase angles; and the superposition operation corresponds to element-wise summation of complex vectors.71% similarUnverifiedAutomatic differentiation dynamically constructs a directed acyclic graph (computation graph) by recording each operation and its inputs during every forward computation, and during backpropagation it traverses the graph's reverse edges, sequentially invoking each operation's local gradient function to accumulate gradients via the chain rule63% similarUnverifiedStride records the number of memory units that must be skipped to move one step in each dimension, enabling operations such as transposition and slicing to be completed by modifying strides without copying data63% similarUnverifiedAfter determining the ordering, HOST recovers the parent set of each node by recursively stripping indirect effects from the total effect between pairs of nodes.62% similarUnverifiedThe self-attention mechanism captures dependencies of arbitrary distance in a single forward pass by dynamically computing association weights between an element and all other elements in the sequence, overcoming the long-range dependency difficulties caused by vanishing gradients in RNNs/LSTMs.61% similar
