Mojo struct
CausalConv1DVarlenFwd
struct CausalConv1DVarlenFwd[activation: StringSlice[StaticConstantOrigin]]
Varlen causal 1D convolution forward pass.
Performs causal 1D convolution on variable-length sequences that are concatenated together. Uses cumulative sequence lengths to identify sequence boundaries.
Tensor Shapes: - output: (dim, total_seqlen) - Output tensor - x: (dim, total_seqlen) - Input tensor (concatenated sequences) - weight: (dim, width) - Convolution weights per channel - bias: (dim,) - Per-channel bias - query_start_loc: (batch + 1,) - Cumulative sequence lengths - cache_indices: (batch,) - Indices into conv_states (optional) - has_initial_state: (batch,) - Whether to use initial state (optional) - conv_states: (batch, dim, width - 1) - Conv states (optional, in/out)
Parameters
- activation (
StringSlice[StaticConstantOrigin]): Activation function - "none" or "silu".
