Dr Ajaz Ahmad Bhat is an Assistant Professor of Intelligent Robotics at the Faculty of Science, Universiti Brunei Darussalam, Brunei, and a visiting researcher at the Okinawa Institute of Science and Technology, Japan. Prior to this posting, he worked as a Senior Research Associate at the University of East Anglia, UK, and then as an Assistant Professor at the University of Twente, Netherlands. Ajaz’s research interests lie at the intersection of intelligent robotics, cognitive sciences, and consumer technologies with a special focus on understanding and designing developmental and cumulative learning systems. His research outputs have been published in more than 15 journal articles with some of them in top-tier journals such as Psychological Review and Autonomous Robots. His work on Causal Learning in Robots was covered in top conferences like ICML and by media outlets such as BBC. He has been involved in multiple international research projects such as EU’s FP7 DARWIN and NIH’s WOLVES. Ajaz retains memberships of both IEEE and APS societies in addition to holding a Ph.D. in Cognitive Robotics from the Istituto Italiano di Tecnologia (IIT), Italy.

• Connectionist, dynamical, multi-time scale, and integrated systems approach to intelligence
• AI robots for problem-solving, motor behaviours, causal reasoning, imagination, and creativity

Deep learning excels at training powerful models from fixed datasets and stationary environments, often exceeding human-level ability. Yet, these models fail to emulate human learning, which is robust, incremental, compositional, constructive, and predictive from sequential experience to reason beyond experience. This project investigates mechanisms that can encode, recall and exploit diverse past experiences of an agent to imagine the future and solve non-trivial problems creatively. Approaches include at the most granular level, with gradient-based methods, as well as at the architectural level, with modular and memory-based, and meta-learning methods. The project will help understand the theoretical capabilities and limitations of AI, it will also pave the way towards creating AI systems that are explainable, controllable, reliable, and dependable — a major challenge with existing AI. Methodologies include dynamical systems, neuro-symbolic AI, episodic memory, predictive coding, reinforcement, self-supervising, and self-organizing networks.
How do humans imitate, learn and recycle skilled actions including the use of tools? This project develops different representations of the body, movement, and peri-personal spaces to enable learning of dynamic task-specific trajectory planning, body-chain engagement, motor control, and prediction. The project investigates how the motor knowledge acquired by a robot during learning a skill like drawing can be recycled in a completely different skill like the use of a tool. The project will look for designing a full-blown procedural memory and identifying mechanisms that allow humans (and robots) to generate any form of complex actions at runtime through shape compositionality and recycling of stable/metastable movement patterns emergent at phase transitions in different neural states. Methodologies employed include neuro-symbolic AI, predictive coding, control theory, RL, deep learning transformers, and self-organizing networks.
Language is grounded in sensory-motor experiences not word embeddings. Agents must interact physically with their world to grasp the essence of words and context. This project builds agents (and interactive robots) in simulated environments that learn and understand language via multisensory grounding (and robotic embodiment). The goals are two-fold. First, the project is using computational models to gain insights into how children acquire language over development. By building and testing models with near-realistic environments, we test psychological theories of human cognition and language acquisition. Second, we build a new generation of instructible language models with richer semantic representations leading to more intelligent machine behavior. Methodologies employed include dynamic field theory, neuro-symbolic AI, deep reinforcement learning, and transformer networks.
