More on Deep Q networks

Nature cover

It’s time for another blog post apparently! Just as last time, I have decided to fill it with science! This time I will talk mostly about the “Deep Q Network” and the “Stochastic Gradient Descent” algorithm. These are all fairly

El Niño around the world

In my last post, I explained what El Niño events were about. In general, El Niño events are part of a bigger oscillation pattern in the climate of Earth called ENSO (El Niño-Southern Oscillation) that changes patterns in temperature and

Which is the busiest node in the HPC cluster

What is a high-performance computer (HPC)? In simple terms, nowadays it is a cluster of innumerous ‘mini’ computers (nodes) interlinked by the same network. When a big calculation is submitted to the HPC, it will be fragmented into thousands of
