Machine-translated · View original
A lab that uses p-adic numbers as a starting point to explore derived rigid geometry and optimization.

AboutAbout the lab
Exploring mathematics and data through p-adic numbers
The Mihara Lab studies derived rigid geometry, p-adic functional analysis, discrete optimization, and natural language processing.
It belongs to the Algebra Group of the Mathematics Degree Program and is also assigned to the Center for Artificial Intelligence Research.
The lab also reports, in papers and presentations, on research that uses p-adic numbers for data analysis and word embeddings.
Key terms
- p-adic numbers
- Numbers used in number theory and analysis that form a system separate from the real numbers. One system is considered for each prime p.
- Discrete optimization
- A field that deals with the problem of choosing the best combination from among discrete options.
- Word embeddings
- A method that represents words as vectors of numbers so that the meanings of words can be handled computationally.
