Dynamic fine‐tuning layer selection using Kullback–Leibler divergence

open access: yesEngineering Reports, 2023
The selection of layers in the transfer learning fine‐tuning process ensures a pre‐trained model's accuracy and adaptation in a new target domain. However, the selection process is still manual and without clearly defined criteria. If the wrong layers in

Model Fusion with Kullback--Leibler Divergence

open access: yesCoRR, 2020
We propose a method to fuse posterior distributions learned from heterogeneous datasets. Our algorithm relies on a mean field assumption for both the fused model and the individual dataset posteriors and proceeds using a simple assign-and-average approach.

Generalizing the Alpha-Divergences and the Oriented Kullback–Leibler Divergences with Quasi-Arithmetic Means

open access: yesAlgorithms, 2022
The family of α-divergences including the oriented forward and reverse Kullback–Leibler divergences is often used in signal processing, pattern recognition, and machine learning, among others.

Optimism in reinforcement learning and Kullback-Leibler divergence [PDF]

open access: yes2010 48th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2010
We consider model-based reinforcement learning in finite Markov De- cision Processes (MDPs), focussing on so-called optimistic strategies. In MDPs, optimism can be implemented by carrying out extended value it- erations under a constraint of consistency with the estimated model tran- sition probabilities.

The AIC Criterion and Symmetrizing the Kullback–Leibler Divergence [PDF]

open access: yesIEEE Transactions on Neural Networks, 2007
The Akaike information criterion (AIC) is a widely used tool for model selection. AIC is derived as an asymptotically unbiased estimator of a function used for ranking candidate models which is a variant of the Kullback-Leibler divergence between the true model and the approximating candidate model.

Kullback-Leibler divergence and the Pareto-Exponential approximation. [PDF]

open access: yesSpringerplus, 2016
Recent radar research interests in the Pareto distribution as a model for X-band maritime surveillance radar clutter returns have resulted in analysis of the asymptotic behaviour of this clutter model. In particular, it is of interest to understand when the Pareto distribution is well approximated by an Exponential distribution.

Algorithms for Nonnegative Matrix Factorization with the Kullback–Leibler Divergence [PDF]

open access: yesJournal of Scientific Computing, 2021
Nonnegative matrix factorization (NMF) is a standard linear dimensionality reduction technique for nonnegative data sets. In order to measure the discrepancy between the input data and the low-rank approximation, the Kullback-Leibler (KL) divergence is one of the most widely used objective function for NMF.

Zipf–Mandelbrot law, f-divergences and the Jensen-type interpolating inequalities

open access: yesJournal of Inequalities and Applications, 2018
Motivated by the method of interpolating inequalities that makes use of the improved Jensen-type inequalities, in this paper we integrate this approach with the well known Zipf–Mandelbrot law applied to various types of f-divergences and distances, such ...

Android Malware Detection Using Kullback-Leibler Divergence

open access: yesAdvances in Distributed Computing and Artificial Intelligence Journal, 2015
Many recent reports suggest that mareware applications cause high billing to victims by sending and receiving hidden SMS messages. Given that, there is a need to develop necessary technique to identify malicious SMS operations as well as differentiate ...

Divergence Measure of Belief Function and Its Application in Data Fusion

open access: yesIEEE Access, 2019
Divergence measure is widely used in many applications. To efficiently deal with uncertainty in real applications, basic probability assignment (BPA) in Dempster-Shafer evidence theory, instead of probability distribution, is adopted.
