A Randomised Subspace Gauss-Newton Method for Nonlinear Least-Squares

no code implementations10 Nov 2022 Coralia Cartis, Jaroslav Fowkes, Zhen Shao

We propose a Randomised Subspace Gauss-Newton (R-SGN) algorithm for solving nonlinear least-squares optimization problems, that uses a sketched Jacobian of the residual in the variable domain and solves a reduced linear least-squares on each iteration.

A Subsequence Interleaving Model for Sequential Pattern Mining

1 code implementation16 Feb 2016 Jaroslav Fowkes, Charles Sutton

Recent sequential pattern mining methods have used the minimum description length (MDL) principle to define an encoding scheme which describes an algorithm for mining the most compressing patterns in a database.

A Bayesian Network Model for Interesting Itemsets

1 code implementation14 Oct 2015 Jaroslav Fowkes, Charles Sutton

Mining itemsets that are the most interesting under a statistical model of the underlying data is a commonly used and well-studied technique for exploratory data analysis, with the most recent interestingness models exhibiting state of the art performance.
