New papers at NIPS and ACML

Our paper "Non-Stationary Spectral Kernels" is going to presented as a poster at NIPS 2017. The paper extends spectral mixture kernels into non-stationary kernels. Important features over previous proposals for non-stationary kernels include the ability to approximate any non-stationary kernel, and especially non-monotonic kernels, with some type of periodicity.

Another paper titled "A Mutually-Dependent Hadamard Kernel for Modelling Latent Variable Couplings" will also be presented at ACML 2017 both as oral as well as a poster presentation. This paper introduces a multi-output kernel that allows the outputs to have a non-stationary, or input-dependent, correlation structure, in contrast to popular Kronecker structured kernels. While this kernel could be used in plain multi-output prediction, we also deploy the kernel in a latent variable model.

These two papers also constitute the two most important papers to be included in my doctoral dissertation, which I hope will be finished by the end of the year!

WiFi hotspot app for Sailfish / Jolla

My new wonderful Jolla phone missed a WiFi hotspot app, so I decided to write one myself.

GitHub repository can be found at https://github.com/sremes/harbour-hotspot. An RPM package is also available for install.

If you try this, please note that this is a very first version, and may contain bugs. It relies on the Connection Manager (connman) bindings for QT5 to enable the WiFi tethering functionality.

Edit: If you found this through Google or something, there is now a better app now available in Jolla Store called Tethering by jlehtoranta, and you probably should use that instead.

Blog or website

Not sure if I'm going to start blogging or not, but WordPress seems also a good platform for static content.

Most probably the only thing I'm going to write about is some scripts or short tips on Linux and other open source software.
