Combinatorial continuum limits and their applications in data science
Add to Google Calendar
Many problems in data science fields including signal processing, machine learning, and data mining involve combinatorial optimization of some kind, e.g., computation of minimal graphs and graph cuts over feature space. Several classes of combinatorial optimization problems have continuum limits as the dimension approaches infinity. These include problems arising in spectral clustering, multi-objective learning, and anomaly detection. In some cases these continuum limits lead to analytical approximations that can break the computational combinatorics bottleneck. In this talk, I will present an overview of the theory and application of continuum limits for combinatorial problems.
