3.1 What is the KL Divergence? KL Divergence is a measure of how much one probability distribution differs from another. It’s not a true “distance” metric (since it’s not symmetric), but rather a way to quantify the “divergence” or mismatch between two distributions. In simpler terms...
When there is high KL divergence, there is a strong probability distribution and an even (flat) marginal distribution -- each image has a distinct label (such as a cat), but the overall set of images has many different labels. This yields the highest inception score. Finally, the IS algor...
KL divergence Kullback-Leibler (KL) divergence measures the difference between two probability distributions. When used in the context of SAEs, the penalty given to the network after each training batch is proportionate to the KL divergence between the target distribution of activation values—the desi...
Because there can be multiple soft targets for each training example, distillation loss measures the difference between theprobability distributionof the teacher network’s soft targets and the probability distribution of the student’s. Kullback-Leibler divergence (or “KL divergence”) is commonly used...
called theKullback-Leibler divergence function. The KL divergence represents differences between the learned distribution and a predetermined statistical distribution. VAEs minimize the KL divergence by maximizing the evidence lower bound, or ELBO, which is the observable input data the VAE is responsible...
the ML engineering team keeps a copy of the original LLM in the RL loop. The difference between the output of the original and RL-trained LLMs (also called the KL divergence) is integrated into the reward signal as a negative value to prevent the model from drifting too much from the or...
Afterlife x Goen - Divergence. Kick off your Friday with an event that transcends traditional notions of freedom. It will be a unique audio-visual experience that combines a 270-degree projection map with a night of non-stop music. What kind of music, you may ask? One that...

The KL-divergence method considers all activations simultaneously, in contrast to the L1 Loss approach, which merely adds up the activations over all samples. We established upper and lower bounds on the average intensity of each neuron in this group. Contractive Autoencoders Prior to rebuilding ...
