Description

Leader of the group Machine Learning: Peter Grünwald.

Our research group focuses on how computer programs can learn from and understand data, and then make useful predictions based on it. These algorithms integrate insights from various fields, including statistics, artificial intelligence and neuroscience.  

 Machine-learning applications are increasingly part of every aspect of life, from speech recognition on cell phones to illness prediction in healthcare. One common problem is extremely polluted data, for which no single model can provide adequate explanations. At CWI we address this issue with statistical machine learning based on combining predictions from different models and experts in order to achieve reliable conclusions.

We also study how networks of neurons in the brain process information, and how modern deep-learning methods can benefit from neuroscience. We develop novel neural networks, like Deep Adaptive Spiking Neural Networks, and also theoretical models of neural learning and information processing in biology. Applications of our work range from low-energy consumption neural machine learning to neuroprosthetics, to increased insight into the question of how the brain works.

Compared to modern Deep Learning, the human brain needs vastly fewer examples to learn tasks and is massively more energy efficient. The brain’s ability to control, and learn to control, hundreds of flexible and variable muscles for motion remains unsurpassed. Sensory information processing, cognitive deliberation and subsequent muscle control is also an ongoing continuous-time process, a fact mostly ignored in deep learning models. Finally, the brain solves an inherently multi-scale problem: fast high-dimensional sensory information feeds, (relatively) slow and low dimensional cognitive deliberations, which are then translated into fast and high-dimensional muscle activations resulting in typically low-dimensional feedback for learning from the environment in the form of success or failure of actions. Recently, models for a number of components in this sensori-cognitive-motor chain have been proposed.

In this workshop, we aim to bring together experts in computational neuroscience and machine learning to foster collaboration and start working on integrating the various components into coherent end-to-end cognitive models. Specifically, we aim to determine the `missing components’ that are needed to implement fast and effective sensori-cognitive-motor models.

At a high level, the main topics in the workshop include End-to-end time-continuous learning, Multi-level Motion Representation, Planning and Control and Event-based asynchronous neural computation.

The workshop will be held over a 3-day period at CWI, the Dutch National Centre for Mathematics and Computer Science. Invited speakers will bring broad-ranging expertise from neuroscience and machine learning, with a special focus on efficient platforms. The workshop will also have plenty of time for formal and informal discussions.

Participation and deadlines

Participation in the workshop is free of charge and includes the lunches for the three days. However, the workshop is limited to a restricted number of people given the capacity of the venue and the aim of the event. Prospective attendees should express their interest in participating by submitting the form downloadable from the link below, and their willingness to contribute a poster. For the poster, people are also invited to submit a short/extended abstract (max 2 pages), possibly including figures. The submissions will be selected on the basis of the quality and of how well they fit the workshop’s aims.

Both senior and young researchers, including Ph.D. students, are encouraged to submit to ensure a full representation of the community.

Deadline: 11.07.2019

Please use this form and submit it and the optional abstract (subject: “EANCC submission: name, last name”) to: eancc2019@gmail.com
