Viewed 14 times 0 I am trying to train a supervised variational autoencoder to perform classification for a noisy dataset. I am using a fully connected encoder and decoder where uses the z as input for an MLP. WebNov 1, 2024 · KL (P Q) = – sum x in X P (x) * log (Q (x) / P (x)) The value within the sum is the divergence for a given event. This is the same as the positive sum of probability of each event in P multiplied by the log of the probability of the event in P over the probability of the event in Q (e.g. the terms in the fraction are flipped).

WebThis differs from the standard mathematical notation K L (P ∣ ∣ Q) KL(P\ \ Q) K L (P ∣∣ Q) where P P P denotes the distribution of the observations and Q Q Q denotes the model. Warning reduction = “mean” doesn’t return the true KL divergence value, please use reduction = “batchmean” which aligns with the mathematical definition.

The reason it came out zero is probably an implementation issue and not because the true calculation using the estimated probabilities gave a negative result.
WebThis study considers a new decomposition of an extended divergence on a foliation by deformed probability simplexes from the information geometry perspective. In particular, we treat the case where each deformed probability simplex corresponds to a set of q-escort distributions. For the foliation, different q-parameters and the corresponding α …
