The KL divergence measures the similarity of two distribution functions and penalizes extreme distances. In this case, using a KL penalty reduces the distance that the responses can be from the SFT model outputs trained in step 1 to ... WebMay 28, 2024 · One application of the K-L divergence is to measure the similarity between a hypothetical model distribution defined by g and an empirical distribution defined by f. Example data for the Kullback–Leibler divergence As an example, suppose a call center averages about 10 calls per hour.

WebIntroduction. Often in real-world applications, we need some measure to compare probability distribution. Normal metrics are not useful in such cases and thus we need some other useful measure. Divergence measures are the measures that are normally used for this task.

WebDec 6, 2024 · The KL divergence of distribution P from distribution Q is about 0.589. Note that the units used in this calculation are known as nats, which is short for natural unit of information. Thus, we would say that the KL divergence is 0.589 nats. Also note that the KL divergence is not a symmetric metric.
WebFeb 2, 2024 · KL divergence is a non-symmetric metric that measures the relative entropy or difference in information represented by two distributions. It can be thought of as measuring the distance between two data distributions showing how different the two … WebThe reverse KL divergence is said to be “mode-seeking”. This means that the divergence will be low when q q places density only where p p places density, and the divergence will be high when q q places density where p p does not.
