Machine Learning for Multi-modal Sensor Processing

Recent breakthroughs in the application of neural networks, deep learning and Bayesian models have put machine learning in the forefront of technological innovations. We address the improvement of machine learning techniques, driven by their application in new and challenging application domains, such as the automatic translation of sign language, the extraction of information from EEG data, condition monitoring, emotion recognition, or the control of ‘black box’ nonlinear dynamical systems based on noisy sensor data.

We have considerable experience with applications involving sequential data, in which information about past inputs needs to be incorporated in the model (e.g., detection of events in sequences, time series prediction, open loop and closed loop control, dynamical system modeling). We perform research into deep architectures such as convolutional neural networks, deep RNNs and LSTMs, deep generative models and deep reinforcement learning, as well as transfer learning for such architectures. We also apply other machine learning techniques targeted at self calibration and transfer learning in EEG-based brain-computer interfaces (BCI) for communication and control.

As a sideline, we maintain a considerable track record in online machine learning competitions using state-of-the-art deep learning techniques, extensively relying on GPU acceleration:
