The Function-Representation Model of Computation

Cognitive Architectures are the forefront of our research into developing an artificial cognition. However, they approach the problem from a separated memory and program model of computation. This model of computation poses a fundamental problem: the knowledge retrieval heuristic. In this paper we propose to solve this problem by using a new model of computation, one where the memory and the program are united: the Function-Representation. We propose a novel model of computation based on implementing and using these Function-Representations, and we explore its potential through mathematical definitions and proofs. We also talk about different ways to organise multiple Function-Representations, and explore the kind of functions that these Function-Representations can implement. Finally, we also explore the limitations of our proposal.

The Function-Representation Unification Framework

Cognitive Architectures are the forefront of our research into developing an artificial cognition. However, they approach the problem from a separated memory and program model of computation. This model of computation poses a fundamental problem: the knowledge retrieval heuristic. In this paper we propose to solve this problem by using a new model of computation, one where the memory and the program are united: the Function-Representation. We propose a whole framework about how to implement and use these Function-Representations, and we explore their potential through mathematical definitions and proofs. We also talk about different ways to organise multiple Function-Representations, and explore the kind of functions that these Function-Representations can implement. Finally, we also explore the limitations of our proposal.

Knowledge Discovery using Unsupervised Cognition

Knowledge discovery is key to understand and interpret a dataset, as well as to find the underlying relationships between its components. Unsupervised Cognition is a novel unsupervised learning algorithm that focus on modelling the learned data. This paper presents three techniques to perform knowledge discovery over an already trained Unsupervised Cognition model. Specifically, we present a technique for pattern mining, a technique for feature selection based on the previous pattern mining technique, and a technique for dimensionality reduction based on the previous feature selection technique. The final goal is to distinguish between relevant and irrelevant features and use them to build a model from which to extract meaningful patterns. We evaluated our proposals with empirical experiments and found that they overcome the state-of-the-art in knowledge discovery.

Unsupervised Cognition

Unsupervised learning methods have a soft inspiration in cognition models. To this day, the most successful unsupervised learning methods revolve around clustering samples in a mathematical space. In this paper we propose a state-of-the-art primitive-based unsupervised learning approach for decision-making inspired by novel cognition models. This representation-centric approach models the input space constructively as a distributed hierarchical structure in an input-agnostic way. We compared our approach with current state-of-the-art in unsupervised learning classification, and with current state-of-the-art in cancer type classification. We show how our proposal outperforms previous state-of-the-art. We also evaluate some cognition-like properties of our proposal where it not only outperforms the compared algorithms (even supervised learning ones), but it also shows a different, more cognition-like, behaviour.

Reducing Diversity to Generate Hierarchical Archetypes

The Artificial Intelligence field seldom address the development of a fundamental building piece: a framework, methodology or algorithm to automatically build hierarchies of abstractions. This is a key requirement in order to build intelligent behaviour, as recent neuroscience studies clearly expose. In this paper we present a primitive-based framework to automatically generate hierarchies of constructive archetypes, as a theory of how to generate hierarchies of abstractions. We assume the existence of a primitive with very specific characteristics, and we develop our framework over it. We prove the effectiveness of our framework through mathematical definitions and proofs. Finally, we give a few insights about potential uses of our framework and the expected results.
