Hi there! My name is Dovydas Joksas, aka Yoshke. I’m a PhD candidate at University College London (UCL) where I investigate machine learning hardware. I also tutor GCSE, A-level and IBDP students in mathematics and physics. Finally, I’ve recently founded Ab Initio AI—a startup aimed at developing intelligent diagnostic tools that aid students’ learning.

Artificial neural networks (ANNs) have achieved spectacular results over the last decade, but at a cost of low efficiency. Our conventional computer hardware is not well suited to the computations that ANNs perform and so a lot of time and energy is wasted. One of the suggested alternatives is an emerging technology—memristor-based hardware. Although vastly more efficient, memristor-based implementations exhibit a greater degree of volatility and uncertainty than the digital computers that we use every day.
Using simulations, I investigate to what extent the accuracy of ANNs is affected when memristor-based hardware is used to implement them. I am also interested in whether the accuracy can be increased not by optimising device performance, but by using different software approaches. I explain the rationale behind the research in less technical terms here, here and here.
