School on Analytical Connectionism — 2025 —

Analytical Connectionism is a 2-week summer course on analytical tools, including methods from statistical physics and probability theory, for probing neural network models of higher-level cognition. The course brings together neuroscience, psychology and machine-learning communities, and introduces attendees to analytical methods for neural network analysis and connectionist theories of higher-level cognition and psychology.

Connectionism, a theoretical approach in cognitive science, uses neural network models to simulate a wide range of phenomena, including perception, memory, decision-making, language, and cognitive control. However, most connectionist models remain, to a certain extent, black boxes, and we lack a mathematical understanding of their behaviours. Recent progress in machine learning theory has provided novel analytical tools that have advanced our mathematical understanding of deep neural networks, and have the potential to help make these “black boxes” more transparent.

During the School, teams of students work closely with faculty and postdoc mentors to develop research projects on topics related to analytical connectionism, presenting initial proposals during week one and interim results at the School’s conclusion.

Additionally, students are grouped based on their expertise and preferences and assigned to take notes for a specific lecturer. These notes are peer-reviewed and collected into a special issue, creating a permanent resource for the community and giving note-takers the opportunity to contribute to a formal publication; the 2023 and 2024 notes are already published.

This course will introduce:

• mathematical methods for neural network analysis, providing a solid overview of the analytical tools available to understand neural network models;
• key connectionist models with links to experimental observations, which provide targets for analytical results.

During the course, you will:

• attend lectures given by leading researchers on theoretical methods and applications, key connectionist models, and experimental observations;
• participate in tutorials, Q&A sessions, and panel discussions;
• present to and engage with lecturers, organisers, and other participants during a poster session;
• work in a group with other participants on a novel research project, mentored by the course organisers and lecturers.

This year’s school will feature lecturers with expertise in the following research areas:

• analytical frameworks for understanding bias from statistical physics;
• perceptual and cognitive biases in human decision-making and belief formation;
• individual differences and deficits in learning, including atypical development and atypical cognitive processes;
• social learning and the emergence of group-level stereotypes;
• bias amplification in machine learning systems from theoretical and applied perspectives;
• clinical applications in computational psychiatry and mental health.

These components will be delivered as a set of core lectures in the first week, followed by a set of topic lectures in the second week.

Target audience

This course is appropriate for graduate students, postdoctoral fellows and early-career faculty in a number of fields, including psychology, neuroscience, physics, computer science, and mathematics. Attendees are expected to have a strong background in one of these disciplines and to have made some effort to introduce themselves to a complementary discipline.

The course is limited to no more than 40 participants, who will be chosen to balance the representation of different fields. In circumstances where all other things are equal, priority will be given to applicants from underrepresented groups in STEM fields, using positive action under the UK Equality Act 2010 where appropriate.

Course fees

There is a course fee of 600 GBP. Attendees are expected to cover their own travel, accommodation and other subsistence expenses. Lunch and coffee/tea breaks will be provided on course days, and there will be one course dinner.

Cancellation policy:

• Within 7 days of registering/making the booking: 100% refund
• After 7 days of registering/making the booking and up to 15 days before the start of the school: 80% refund
• Less than 15 days before the start of the school: no refund

Financial assistance via travel grant may be available for successful applicants who find it difficult to take up a place for financial reasons. Applicants are asked to indicate in their application if they would like to be considered for financial aid. The amount of financial aid available will depend on the course funding from grants and sponsors.
