Welcome! My name is Jeff Matayoshi, and I am a research scientist at ALEKS Corporation, a subsidiary of McGraw Hill. I am part of a group that is responsible for developing and improving the technology behind the adaptive and artificially intelligent components of the ALEKS assessment and learning products.
A mathematician by training, my graduate research was in the area of probability, where I studied the behavior of random polynomials in various settings. Nowadays, my research interests have expanded to include, at a general level, the areas of artificial intelligence in education, educational data mining, and combinatorics. More specifically, I am interested in applying artificial intelligence and machine learning techniques, as well as sound statistical methodology, to the challenge of improving educational technology. I also work in the area of knowledge space theory, a branch of mathematics and combinatorics that forms the foundation of the ALEKS system. Lastly, I dabble in extremal set theory (mostly while my kids are napping), making fruitless and misguided attempts at solving the union-closed sets conjecture.
