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…
Meeting an absolute test information target with optimal number of test items via Grand Canonical Monte Carlo simulation
Stefan M. F|ilipov, Ivan D. Gospodinov
This work studies IRT-based Automated Test Assembly (ATA) of multiple test forms (tests) that meet an absolute target information function, i.e. selecting from an item bank only th…
Shooting-Projection Method for Two-Point Boundary Value Problems
Stefan M. Filipov, Ivan D. Gospodinov, Istvan Farago
This paper presents a novel shooting method for solving two-point boundary value problems for second order ordinary differential equations. The method works as follows: first, a gu…
