Neuromorphic computing: Overcoming computational challenges in AI with innovative hardware paradigms

Machine learning, and in particular a class of algorithms called Deep Learning, has revolutionized a large number of application domains in recent years. However, the increased capacities of these algorithms come at a price: ever increasing demands for computation. This poses today two fundamental problems: firstly, training of state-of-the-art models has become prohibitively expensive, with only a handful of actors worldwide being capable of training the most advanced models from scratch. Secondly, even when these models are trained, their energy and memory consumption is incompatible with the constraints of most embedded systems, which hinders their use in mobile and autonomous systems. At the same, Moore’s law, which has for a long time been a guarantor for the continuing growth of computation power, seems to be stagnating. Therefore, the rise of Deep Learning has caused a renaissance in the search for novel computing paradigms: algorithm developers, IC designers, neuroscientists and material scientists are starting to work together to surmount the limits of current digital hardware. This talk will give a high level introduction to the current advances and challenges in the field of machine learning, with a focus on the different hardware paradigms that are proposed to overcome these problems.
