Robotics research is facilitated with a 75m2 robot arena with VICON tracking system.
If you are considering to study for MRes or PhD in any of the topics below or other related topics please email Dr Cosma.
Areas of research interest include:
Continual/Lifelong Deep Learning: Training deep neural networks to learn a very accurate mapping from inputs (such as image data, sensor data, text) to outputs (e.g. labels also known as classes) requires large amounts of labelled data. Even when these models are trained, they have limited ability to generalise to conditions which are different to the ones used for training the model. Projects under this topic concern the development of Continual/Lifelong learning algorithms which can learn continuously and adaptively, to autonomously and incrementally develop complex skills and knowledge. Projects include the development of methods for recognising new behaviours in various environments such as smart environments (e.g. cities, homes, healthcare settings), and continuous object recognition.
Deep Feature Selection: Feature selection using Deep Neural Networks has not been well studied, despite its importance which facilitates understanding of data. Projects under this topic concern the development of algorithms which are capable of removing irrelevant features from large unimodal and multi-modal datasets. Projects include detection and analysis of anomalous data in various environments such as smart environments.
Deep learning for noisy imbalanced data: It is a challenging task to train deep learning models on imbalanced data which is commonly generated in real-time scenarios. The complexity escalates when training deep learning algorithms on multi-modal data spaces. Projects include the development of algorithms for classifying imbalanced data obtained from smart environments.
Training Deep Learning algorithms with fewer examples: One-shot and few-shot learning is the act of learning to generalize from one or a few number of training examples per class, respectively. This project concerns the development of k-shot learning algorithms which can learn multi-modal data obtained from various environments using fewer labelled examples. For example, a robot can be taught to learn policies and determine which policy or solution to choose next whilst exploring their environments.
Artificial Intelligence algorithms and reasoning: The emphasis of this project is the design and development of artificial intelligence algorithms which can provide reasoning behind predictions and decisions. Applications where reasoning is particularly needed include biomedical and legal applications.
Multi-modal Information Retrieval: Possible projects include developing algorithms which can optimise retrieval of multi-modal data when given queries in image or textual format, and algorithms for multi-modal cross-lingual (Greek and English) information retrieval systems.
Robot Imitation Learning from Multi-Modal Human Demonstrations: Imitation learning in robots is when a robot is presented with a demonstration of a skill that it should learn to perform on its own.This project will develop a solution to enable robots to exploit and fuse a range of data sources collected during a demonstration. The instructor can be a human or robot instructor performing an action that the robot should imitate. The CNCR Group has several robots that are utilised for imitation learning. One of which is the Sawyer Robot.
