Cobweb: An Incremental and Hierarchical Model of Human-Like Category Learning

no code implementations6 Mar 2024 Xin Lian, Sashank Varma, Christopher J. MacLellan

Cobweb, a human like category learning system, differs from other incremental categorization models in constructing hierarchically organized cognitive tree-like structures using the category utility measure.

Avoiding Catastrophic Forgetting in Visual Classification Using Human Concept Formation

no code implementations26 Feb 2024 Nicki Barari, Xin Lian, Christopher J. MacLellan

Deep neural networks have excelled in machine learning, particularly in vision tasks, however, they often suffer from catastrophic forgetting when learning new tasks sequentially.

VAL: Interactive Task Learning with GPT Dialog Parsing

no code implementations2 Oct 2023 Lane Lawley, Christopher J. MacLellan

By using LLMs only for specific tasks--such as predicate and argument selection--within an algorithmic framework, VAL reaps the benefits of LLMs to support interactive learning of hierarchical task knowledge from natural language.

Interactive Learning of Hierarchical Tasks from Dialog with GPT

no code implementations17 May 2023 Lane Lawley, Christopher J. MacLellan

We present a system for interpretable, symbolic, interactive task learning from dialog using a GPT model as a conversational front-end.

Efficient Induction of Language Models Via Probabilistic Concept Formation

no code implementations22 Dec 2022 Christopher J. MacLellan, Peter Matsakis, Pat Langley

The framework builds on Cobweb, an early system for constructing taxonomic hierarchies of probabilistic concepts that used a tabular, attribute-value encoding of training cases and concepts, making it unsuitable for sequential input like language.

Convolutional Cobweb: A Model of Incremental Learning from 2D Images

no code implementations18 Jan 2022 Christopher J. MacLellan, Harshil Thakur

This paper presents a new concept formation approach that supports the ability to incrementally learn and predict labels for visual images.
