Integrating structured knowledge with Machine Learning Representations


Project Description

he problem: Machine learning systems are effective at learning from scratch, but it is not clear how to reuse the knowledge they have learned for another purpose. The knowledge is “entangled” in the network, and tied to the task the system was trained for. In addition, it is also not clear how a typical machine learning system, could take advantage of existing prior conceptual knowledge; instead they usually learn from scratch.

The project: This project will investigate how conceptual knowledge can be integrated with the representations of typical machine learning systems. This is a combination of the symbolic with the subsymbolic, with the aim of achieving a more human-like cognition. We aim to come up with representations which are, at a high level, composed of parts meaningful to humans, but which also connect to subsymbolic representations at a low level, so that they can integrate with typical learning techniques. This project will build a more human-like representation of a set of concepts, grounded in subsymbolic representations. The project will also build a system for conceptual reasoning, which can apply these concepts to do reasoning with real data in language or computer vision. Our representations will build on cognitive science works that provide alternative views of concepts. Although the project is to be based at Aberdeen, we will also collaborate with experts outside Aberdeen.

Candidates should have (or expect to achieve) a UK honours degree at 2.1 or above (or equivalent) in Computer Science or Informatics. Other closely related backgrounds can also be considered, like Engineering or Mathematics with computer algorithms experience (e.g. in Matlab).

It is essential that the successful applicant has a background in Computer Science knowledge (programming, algorithms, data structures, confident in machine learning relevant mathematics. Knowledge of programming is important and some knowledge of machine learning is desirable.
