The Faculty of Science and the Leiden Institute of Advanced Computer Science (LIACS) is looking for a:
PhD Candidate on Exploring Pareidolia in Computer Vision to Enhance Interpretability, Robustness, and Creativity in AI
Why does an AI think something is a face —or not? This PhD project investigates pareidolia—the brain’s tendency to perceive faces in non-face visuals such as clouds, sockets, and tree trunks—as a tool to enhance interpretability, robustness, and creativity in computer vision. While human vision is remarkably adaptive and creative, current AI models struggle to recognize or convincingly generate pareidolic patterns. Understanding why this gap between human and machine perception emerges can guide the development of more human-like AI systems.
Pareidolia is deeply embedded in human perception and has inspired art and creativity —for example, in Salvador Dali’s ‘Slave Market with the Disappearing Bust of Voltaire’. The project will explore the interplay between pareidolia, creativity, and aesthetics, particularly through the lens of generative AI. This line of inquiry could inspire AI-generated content, interactive design tools, and emotionally resonant products, especially in the fields like robotics and user experience.
This position offers a unique opportunity to work at the intersection of computer vision, interpretability, human perception, and computational creativity. You will be embedded in the Human AI cluster, at the Leiden Institute for Advanced Computer Science (LIACS) at Leiden University, supervised by dr. Derya Soydaner, dr. Joost Broekens, and dr. Rob Saunders.
Key responsibilities
- Develop, fine-tune, and evaluate computer vision models (e.g., CNNs, ViTs, generative models) with an emphasis on interpretability, robustness, and creativity;
- Design and implement experiments to investigate human and machine perception of pareidolia, and conduct original research in computer vision;
- Explore generative AI techniques to synthesize pareidolic imagery and assess model outputs for perceptual and creative relevance;
- Curate and/or utilize benchmark datasets of pareidolic visuals, and apply statistical and machine learning methods to analyze visual data and model behavior;
- Publish and present research findings in leading AI conferences and journals;
- Engage with interdisciplinary concepts from psychology, vision science, and art to enrich research perspectives;
- Contribute to teaching and the open-source dissemination of models and datasets;
- Assist in relevant teaching activities;
Selection Criteria
We are looking for a candidate that meets the following criteria:
- MSc degree in Computer Science, Artificial Intelligence, Machine Learning, or a related field;
- Strong background in image processing, computer vision, and deep learning;
- Excellent programming skills (Python preferred), with experience in large-scale image processing and deep learning frameworks (e.g., PyTorch, Tensorflow);
- Interest in interdisciplinary research at the intersection of AI, human perception, and creativity;
- Familiarity with computer vision tasks (e.g., object detection, face recognition, generative models) and experience with generative AI models is a plus;
- Curiosity or background in vision science, psychology, cognitive science, or art is a plus;
- Self-motivated, creative, and able to work both independently and as a part of a research team;
- Strong analytical and problem-solving skills;
- Excellent written and oral communication skills in English;
- Strong ability to manage multiple tasks and meet deadlines in a dynamic research environment.
