Persistent self-supervised learning principle: Study and demonstration on flying robots

We introduce, study and demonstrate Persistent Self-Supervised Learning (PSSL), a machine learning method for usage onboard robotic platforms. The PSSL model leverages a standard supervised learning method to simplify the learning problem, but acquires training data in an unsupervised and autonomous manner. Using two platforms, a small...

Anomaly detection for internet banking using supervised learning on high dimensional data

Nowadays, a high number of transactions are performed via internet banking. Rabobank processes more than 10 million transactions per day. Most of these transactions are (part of) normal behaviour. On the other hand, some transactions are considered to be out of the ordinary. These anomalous events occur relatively infrequently (less than 10 per...

A Stochastic Approach for Selective Search Algorithms

This thesis introduces a new algorithm that generates candidate proposals for an object detection pipeline. We introduce Stochastic Selective Search (SSS), a segmentation based selective search method, which differs from previous work in two ways. First and most importantly, SSS is much faster than current state-of-the-art algorithms while...

Joint probabilistic pedestrian head and body orientation estimation

This work presents an approach for joint estimation of the pedestrian head and body orientation in the context of active pedestrian safety systems. It involves a probabilistic framework, where a set of orientation-specific detectors are used for each body part for both localization and orientation estimation, their responses being converted to a...

Enhancing BCI Based Navigation by Adding Intention Detection and a Virtual Assistant

If a person is severely disabled, he can be stuck in a wheelchair without being able to effectively control it. One method to regain control is through a Brain Computer Interface (BCI). However, using a BCI for direct input has several drawbacks, such as a low accuracy, low bitrate (causing a delay in input) and high required mental effort. As a...
