Exceeding Information Targets in Fixed-Form Test Assembly

Ivan Gospodinov, Emira Karaibrahimova, Stefan M. Filipov

This work studies the assembly of ability estimation test forms (called tests, for short) drawn from an item bank. The goal of fixed-from test assembly is to generate a large numbe…

Constrained similarity of 2-D trajectories by minimizing the H1 semi-norm of the trajectory difference

Stefan M. Filipov, Ivan D. Gospodinov

This paper defines constrained functional similarity between 2-D trajectories via minimizing the H1 semi-norm of the difference between the trajectories. An exact general solution…
