How to run Half Life 2 Natively on Jetson Nano

I bought a Jetson Nano SBC few years ago. Just for fun, I tinkered with the board to see if I could make it a bit faster: I tried overclocking the CPUs (some instructions available here) and tried moving the rootfs to an external SSD (some instructions available here). However, I didn't figure out any …

Analyzing Connectivity between MEG Channels using PLV

This is a short update to my earlier post on MEG data classification. As a short recap, I managed to get data classification accuracy up to 60-65% - but some of the classes were classified almost systematically incorrectly while two of the classes were categorized almost flawlessly. The classifier was based on classification of interaction …

MEG Signal Classification using PLV and Neural Networks

Despite I've written two posts on modelling MEG signals, I haven't yet written a single post on my attempts to classify the signals. I lately experimented with a new approach and got some results that seemed to be worth documenting. The high-level idea is to first determine which brain regions were interacting and pass this information …

MEG Signal Modeling using Recurrent Neural Networks

This is a short update to my earlier post from 2015 on modeling MEG signals using CRBMs. CRBMs were outdated already at the time I wrote the post and one of the development areas was to try out recurrent neural networks (RNNs). I'm describing here the results of my weekend project on applying RNNs to time series prediction of MEG data. …

Project: 80C188EB Single Board Computer

I used to be quite passionate on x86 and system level programming about 10 years back: I had projects from simple ones (write own simple DOS-like operating system) to hard ones (build own motherboard). I recently went through some of the electronics projects I built in the past and thought it would be nice to document shortly the …

Project: AVR Web Server

I continue documenting my old projects in this post. This time I give a short introduction to an AVR based web server I built in summer 2011: Background I was interested in developing a simple multitasking operating system with minimal network capability already around 2006-2008. During this time I developed a driver for the NE2000 NIC and …

Modeling MEG signals using CRBMs

Machine learning appears to be a hot topic nowadays - which is a good excuse for me to write my first post about Conditional Restricted Boltzmann Machines (CRBMs). I gather here my results on applying CRBMs to magnetoencephalographic (MEG) signals to create a generative model that produces oscillations which resemble the original data. Don't expect anything too scientific from this …
