WebMay 1, 2024 · Benefit from above improvements, the clustering performance of our model is superior to CLR shown in Section 5.5. With respect to entropy regularization, SSC + E [41] is a representative work to reconfigure the ah … WebIts entropy therefore is H ( a 1) = − ( 10 / 25) log 2 ( 10 / 25) − ( 15 / 25) log 2 ( 15 / 25) ≈ 0.970951. For a 1, the sequence of these entropies for k = 1, 2, 3, 4 is ( 0.97, 0.99, 0.92, 1.5). Let's call this the "profile" of a 1. Here, in contrast, are the moving sums of a 4: For k = 2, 3, 4 there is little variation, whence low entropy.
