Multiple kernel learning (MKL) addresses the problem of learning the kernel function from data. Since a kernel function is associated with an underlying feature space, MKL can be considered as a systematic approach to feature selection. Many of the existing MKL algorithms perform kernel learning by combining a given set of base kernels.

This Year 2038 (Y2038 or Y2K38) problem is about the time data type representation. The solution is to use 64-bit timestamps. I started working on the problem while working as an Outreachy intern for kernel developer Arnd Bergmann. Outreachy is a benevolent program that helps new programmers get into open source development.
