Blind deconvolution

In electrical engineering and applied mathematics, blind deconvolution is deconvolution without explicit knowledge of the impulse response function used in the convolution. This is usually achieved by making appropriate assumptions of the input to estimate the impulse response by analyzing the output. Blind deconvolution is not solvable without making assumptions on input and impulse response. Most of the algorithms to solve this problem are based on assumption that both input and impulse response live in respective known subspaces. However, blind deconvolution remains a very challenging non-convex optimization problem even with this assumption. (Wikipedia).

Transformer - Part 8 - Decoder (3): Encoder-decoder self-attention

This is the third video about the transformer decoder and the final video introducing the transformer architecture. Here we mainly learn about the encoder-decoder multi-head self-attention layer, used to incorporate information from the encoder into the decoder. It should be noted that thi
