SparseFillEmptyRowsGrad

public final class SparseFillEmptyRowsGrad

The gradient of SparseFillEmptyRows.

Takes vectors reverse_index_map, shaped `[N]`, and grad_values, shaped `[N_full]`, where `N_full >= N` and copies data into either `d_values` or `d_default_value`. Here `d_values` is shaped `[N]` and `d_default_value` is a scalar.

d_values[j] = grad_values[reverse_index_map[j]] d_default_value = sum_{k : 0 .. N_full - 1} ( grad_values[k] * 1{k not in reverse_index_map})
