Key questions:

Summary: This course provides a survey of computational approaches to understanding human intelligence and cognition. Both psychologists and data scientists are working with increasingly large quantities of human behavioral data. Computational cognitive modeling is the project of understanding behavioral data (and the mind and brain, more generally) by building computational models of the cognitive processes that produce the data. We will cover the goals, philosophy, and technical concepts behind computational cognitive modeling, including model fitting and evaluation. Readings and lectures will survey various computational approaches, including artificial neural networks / deep learning, Bayesian / structured probabilistic models, symbolic and logical systems, and reinforcement learning. We will cover a broad set of psychological applications of these modeling approaches, including learning, memory, decision making, language, categorization, reasoning, and problem solving. Homework assignments will include implementing some of the modeling ideas surveyed in class. Ideally, students will leave the course with a richer understanding of how computational modeling advances cognitive science, how cognitive science can inform research in machine learning and artificial intelligence, and how to fit and evaluate cognitive models for understanding behavioral data.

Please note that this syllabus is not final and there may be further adjustments.

Pre-requisites

Grading

The final grade is based on homeworks (50%), final project (35%), and attendance/participation (15%).

Final project will be done in groups of 2-4 students. A short paper will be turned in describing the project. The project will represent either an substantial extension of one of the homeworks (e.g., exploring some new aspect of one of the assignments), implementing and replicated an existing cognitive modeling paper, or a written paper discussing one of the core modeling topics. The final projects will need to be approved by the instructor at least 6 weeks before the end of the semester.

Course policies

Auditing:
Unfortunately we have no additional spots for auditors due to the large number of previous requests. If we have replied to your request, you may audit pending available seats. Priority goes to registered students and then by date of audit request.

Collaboration:
We encourage you to discuss the homework assignments with your classmates. We expect you to run the simulations and complete the write-ups for the homeworks on your own. Under no circumstance should students look at eachother’s write ups.

Late work:
We will take off 10% for each day a homework or final project is late.

Extra credit:
In the interest of fairness no extra credit will be given.

Preconfigured cloud environment

Students registered for the course have the option of completing homework assignments on their personal computers, or in a cloud Jupyter environment with all required packages pre-installed. Students can log onto the environment using their github login information here.
