Hyperspectral Image Denoising via Deep Block Term Decomposition

Recently, block-term decomposition (BTD) has been successfully applied to hyperspectral image (HSI) processing. In particular, the <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rank-(L, L, 1)</i> BTD, also known as the LL1 decomposition, decomposes the HSI tensor as a sum of component tensors formed by matrix–vector outer products of <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">rank-L</i> cor
