Transfer Learning with Kernel Methods [PDF]

open access: yesNature Communications, 2023
Transfer learning refers to the process of adapting a model trained on a source task to a target task. While kernel methods are conceptually and computationally simple models that are competitive on a variety of tasks, it has been unclear how to develop ...

Integrating Distance Correlation and Adaptive Weighting with RBF Kernel Transformations: A Novel Feature Selection Framework with Application to ECG Arrhythmia Detection [PDF]

open access: yesBioengineering
Accurate feature selection is critical for machine learning in medical diagnosis, yet conventional methods often fail to capture complex non-linear relationships in biomedical data.

Random Forests and Kernel Methods [PDF]

open access: yesIEEE Transactions on Information Theory, 2016
Random forests are ensemble methods which grow trees as base learners and combine their predictions by averaging. Random forests are known for their good practical performance, particularly in high dimensional set-tings. On the theoretical side, several studies highlight the potentially fruitful connection between random forests and kernel methods.

Kernel methods

open access: yes, 2023
This chapter introduces a powerful class of machine learning approaches called kernel methods, which present an alternative to arguably more widely known neural network approaches. Kernel methods can learn even highly nonlinear problems by making an implicit transformation from a low-dimensional input space into a higher-dimensional feature space. This

The kernel polynomial method [PDF]

open access: yesReviews of Modern Physics, 2006
Efficient and stable algorithms for the calculation of spectral quantities and correlation functions are some of the key tools in computational condensed matter physics. In this article we review basic properties and recent developments of Chebyshev expansion based algorithms and the Kernel Polynomial Method.

Data-Driven Supervised Learning for Life Science Data

open access: yesFrontiers in Applied Mathematics and Statistics, 2020
Life science data are often encoded in a non-standard way by means of alpha-numeric sequences, graph representations, numerical vectors of variable length, or other formats. Domain-specific or data-driven similarity measures like alignment functions have

Efficient Kernel Cook's Distance for Remote Sensing Anomalous Change Detection

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
Detecting anomalous changes in remote sensing images is a challenging problem, where many approaches and techniques have been presented so far. We rely on the standard field of multivariate statistics of diagnostic measures, which are concerned about the
