One Self-Configurable Model to Solve Many Abstract Visual Reasoning Problems

1 code implementation15 Dec 2023 Mikołaj Małkiński, Jacek Mańdziuk

With the aim of developing universal learning systems in the AVR domain, we propose the unified model for solving Single-Choice Abstract visual Reasoning tasks (SCAR), capable of solving various single-choice AVR tasks, without making any a priori assumptions about the task structure, in particular the number and location of panels.

A Review of Emerging Research Directions in Abstract Visual Reasoning

no code implementations21 Feb 2022 Mikołaj Małkiński, Jacek Mańdziuk

One of them refers to the observation that in the machine learning literature different tasks are considered in isolation, which is in the stark contrast with the way the AVR tasks are used to measure human intelligence, where multiple types of problems are combined within a single IQ test.

Multi-Label Contrastive Learning for Abstract Visual Reasoning

1 code implementation3 Dec 2020 Mikołaj Małkiński, Jacek Mańdziuk

State-of-the-art systems solving RPMs rely on massive pattern-based training and sometimes on exploiting biases in the dataset, whereas humans concentrate on identification of the rules / concepts underlying the RPM (or generally a visual reasoning task) to be solved.
