Expand description

Cached on-device tensors for the patch embedding.

Created once via EmbeddingCache::new and reused across forward calls, avoiding repeated CPU→device transfers of constant data.

Fields§

§dft_cos: Tensor<B, 2>

DFT cosine basis [K, N] where K = spectral_bins, N = patch_size.

§dft_sin: Tensor<B, 2>

DFT sine basis [K, N].

§channel_one_hot: Tensor<B, 2>

Channel one-hot matrix [C, C].

§spectral_bins: usize§patch_size: usize
