Description

In the last 10 years, Artificial Neural Networks (ANN) revolutionized many scientific fields by solving very difficult practical problems. Convolutional Neural Networks (CNN) is a very popular approach which allowed to reach state-of-the-art accuracies in many different machine learning tasks, featuring a reasonably low memory footprint. In the last years, a new categories of efficient sensors is meeting a growing interest; ULP event-based cameras and audio sensors belong to this category. To efficiently exploit the nature of the data produced by such sensors, a paradigm shift in the way data are acquired and processed could be unavoidable. For this reason, research communities started focusing their interests on less conventional computing paradigms, such as brain-inspired, event-driven computing. Here, both Spiking Neural Networks (SNN) as well as Hyperdimensional Computing (HDC) showed promising results in processing event-based data. Specifically, SNNs have shown to extract robust features from event-driven cameras [1], whereas HDC have proven to be capable to update their simple to cope with environmental changes during operation [2].

In this project, you combine the best of the two worlds (SNNs for feature extraction and HDC for regression) for steering angle prediction based on event-driven cameras. You start by applying an already given SNN on the publicly available MVSEC dataset [3], and later extend it with an HDC regressor.
