PhD Studentship: Causal Representation Learning in Computer Vision

Recent years have witnessed significant strides made by machine learning-based computer vision, thus enabling machines to interpret and understand visual information. However, most machine learning approaches exploit correlational relationships in a training data set to predict a target variable. When these correlations are spurious or unreliable, those methods often lack the ability to reason about the underlying causal relationships that govern visual phenomena. This PhD project aims to address this limitation by focusing on causal representation learning applicable to computer vision. The outcomes of this research will contribute to the growing field of causal reasoning/inference in computer vision.

About the project

The primary objective of this research is to develop novel techniques for learning causal representations from visual data. The entire project will be carried out in two steps. Firstly, we will investigate new deep architectures and algorithms that can capture and encode causal relationships present in visual data. These models should be able to infer the underlying causes behind observed visual patterns. Secondly, we will develop causal reasoning to facilitate various computer vision tasks, such as scene understanding, and action recognition.
