WebLoRa abreviação de long range ou longo alcance, é uma técnica de modulação de espectro de propagação derivada da tecnologia de espectro de propagação de chirp (CSS). LoRa – Tecnologia de Radiofrequência WebΣ = E Λ E T. Now, the whitening matrix is W = ( E Λ 1 / 2) − 1 since covariance matrix of W X is I. The good thing about having an orthonormal basis is that E − 1 = E T. Hence, W = Λ − 1 / 2 E T. Hence, you only need to take inverse of the diagonal matrix, which is a matrix with inverse of the original diagonal entries. WebSource code for kornia.enhance.zca.
