Open peer commentary on the article “A Computational Constructivist Model as an Anticipatory Learning Mechanism for Coupled Agent–Environment Systems” by Filipo Studzinski Perotto. Upshot: In making a contribution to artificial intelligence research, Perotto has taken note of work on human cognition. However, there are certain aspects of human cognition that are not taken into account by the author’s model and that, generally, are overlooked or ignored by the artificial intelligence research community at large.

Open peer commentary on the article “A Computational Constructivist Model as an Anticipatory Learning Mechanism for Coupled Agent–Environment Systems” by Filipo Studzinski Perotto. Upshot: The schema system presented in the target article suffers from problems that had been acknowledged more than ten years ago. The main point is that our world is neither deterministic nor symbolic. Sensory as well as motor noise is ubiquitous in our environment. Symbols do not exist a priori but need to be grounded (...) within our continuous world. In conclusion, I suggest that research on schema-learning systems should tackle small but real-world, continuous, and noisy problem domains. (shrink)

Open peer commentary on the article “A Computational Constructivist Model as an Anticipatory Learning Mechanism for Coupled Agent–Environment Systems” by Filipo Studzinski Perotto. Upshot: Constructivist theory gives a nice high-level account of how knowledge can be autonomously developed by an agent interacting with an environment, but it fails to detail the mechanisms needed to bridge the gap between low levels of sensorimotor data and higher levels of cognition. AI workers are trying to bridge this gap, using task-specific (...) engineering approaches, without any principled theory to guide them; they could use help from psychologists. (shrink)

Open peer commentary on the article “A Computational Constructivist Model as an Anticipatory Learning Mechanism for Coupled Agent–Environment Systems” by Filipo Studzinski Perotto. Upshot: The aim of this commentary is to relate the target article to recent work about how to represent the knowledge acquired from experience by a constructivist agent.

Open peer commentary on the article “A Computational Constructivist Model as an Anticipatory Learning Mechanism for Coupled Agent–Environment Systems” by Filipo Studzinski Perotto. Upshot: The CALM cognitive agent with its learning mechanism, as presented by the author, can be described as “trivially constructivist.” Probably, at best, it can be seen as a model of the empirical abstraction but not of the reflective abstraction. The “intrinsic motivations” in the simulated agent presented as “evaluative signals” sent from the agent’s (...) “body” to its “mind” can be seen as low-level physiological drives. They cannot account for far more sophisticated intrinsic motivations such as curiosity. (shrink)

Open peer commentary on the article “A Computational Constructivist Model as an Anticipatory Learning Mechanism for Coupled Agent–Environment Systems” by Filipo Studzinski Perotto. Upshot: Mainstream AI research largely addresses cognitive features as separate and unconnected. Instead of addressing cognitive growth in this same way – modeling it simply as one more such isolated feature and continuing to uphold a wrong-headed divide-and-conquer tradition – a constructivist approach should help unify many key phenomena such as anticipation, self-modeling, life-long learning, (...) and recursive self-improvement. Since this is likely to result in complex systems with unanticipated properties, all cognitive architecture researchers should aim to implement their ideas in full as running systems to be verified by experiment. Perotto’s paper falls short on both these points. (shrink)

Open peer commentary on the article “A Computational Constructivist Model as an Anticipatory Learning Mechanism for Coupled Agent–Environment Systems” by Filipo Studzinski Perotto. Upshot: Interaction-based models of cognition force anticipatory and constructivist models. The CALM model offers significant development of such models within a machine learning framework. It is suggested that moving to an entirely interactive-based model offers still further advantages.

RESUMO Neste artigo, busca-se desenvolver um exercício de elucubração sobre o conceito de “ordinário do sentido”, proposto inicialmente por Michel Pêcheux. O conceito, contudo, não foi plenamente desenvolvido devido à morte prematura do filósofo francês em 1983. Assim, o que se pretende é conjecturar o que poderia ser este “ordinário do sentido”. Para tal, em acordo com as sugestões de Pêcheux, segue-se explorando a “análise da linguagem ordinária”, conforme proposto por Ludwig Wittgenstein, e sua reinterpretação culturalista elaborada por Michel de (...) Certeau nas “artes de fazer” cotidianas. Ao final do percurso, chega-se a duas hipóteses: a primeira é que o “ordinário do sentido” não configuraria um “aspecto” do sentido (ou a inclusão de novos objetos, como conversas etc.), mas sim um novo paradigma para se exercer a análise de discursos a partir de um “materialismo prático”; a segunda é que pensar o sentido em sua via ordinária faz com o que a análise do discurso tenha de levar em conta as práticas discursivas e seus diagramas de ação. Como singela homenagem às mais de 660 mil vítimas da covid-19 no Brasil, a discussão em torno dos jogos de linguagem e das práticas cotidianas será balizada pela leitura de um post do Memorial Inumeráveis em uma de suas redes sociais.

Context: The advent of a general artificial intelligence mechanism that learns like humans do would represent the realization of an old and major dream of science. It could be achieved by an artifact able to develop its own cognitive structures following constructivist principles. However, there is a large distance between the descriptions of the intelligence made by constructivist theories and the mechanisms that currently exist. Problem: The constructivist conception of intelligence is very powerful for explaining how cognitive development takes place. (...) However, until now, no computational model has successfully demonstrated the underlying mechanisms necessary to realize it. In other words, the artificial intelligence (AI) community has not been able to give rise to a system that convincingly implements the principles of intelligence as postulated by constructivism, and that is also capable of dealing with complex environments. Results: This paper presents the constructivist anticipatory learning mechanism (CALM), an agent learning mechanism based on the constructivist approach of AI. It is designed to deal dynamically and interactively with environments that are at the same time partially deterministic and partially observable. CALM can model the regularities experienced in the interaction with the environment, on the sensorimotor level as well, as by constructing abstract or high-level representational concepts. The created model provides the knowledge necessary to generate the agent behavior. The paper also presents the coupled agent environment system (CAES) meta-architecture, which defines a conception of an autonomous agent, situated in the environment, embodied and intrinsically motivated. Implications: The paper can be seen as a step towards a computational implementation of constructivist principles, on the one hand suggesting a further perspective of this refreshing movement on the AI field (which is still too steeped in a behaviorist influence and dominated by probabilistic models and narrow applied approaches), and on the other hand bringing some abstract descriptions of the cognitive process into a more concrete dimension, in the form of algorithms. Constructivist content: The connection of this paper with constructivism is the proposal of a computational and formally described mechanism that implements important aspects of the subjective process of knowledge construction based on key ideas proposed by constructivist theories.

Upshot: In this response, I address the points raised in the commentaries, in particular those related to the scalability and robustness of the mechanism CALM, to its relation with the CAES architecture, and to the transition from sensorimotor to symbolic.

Gilles Deleuze has become a key reference for the recent debate on virtual technologies, as his conception of the virtual is widely used to argue for the reality of virtuality. Nonetheless some scholars, among which Slavoj Žižek stands out, have warned about the risks of flattening the Deleuzian concept on the tech debate. This paper aims to show why the two concepts of the virtual do not overlap by explaining some features of the Deleuzian virtual that make it incompatible with (...) virtual media. Namely, its intensive dimension, its relationship with the possible and its imperceptible nature. The paper will also claim how differentiating the two concepts opens up wider applications for the Deleuzian virtual while, at the same time, lightening the tech debate of its ontological burden, allowing to approach the issues of virtual technologies from a more fruitful perspective – that is to say, their pictorial functioning.

El presente artículo tiene como objetivo analizar la evolución histórica y cultural de Europa y Asia como términos políticos en la Grecia clásica. Para ello, abordaremos fuentes de diversa índole como Esquilo, Heródoto, el escrito hipocrático Aires, aguas y lugares y el orador Isócrates. Partiremos de la equiparación inicial entre Europa y Asia hasta alcanzar la propuesta de Isócrates de considerar a Filipo como un líder europeo.

Este trabajo tiene por objetivo analizar Hch 16 en tanto relato organizado por el autor en base a las tensiones de las ἐκκλησίαι de inicios del siglo II. Identificaremos en la narración cómo se representan las inquietudes por el liderazgo comunitario y la forja de una identidad grupal. En el primer caso, la interacción de Pablo con los οἶκοι filipenses propicia una reflexión acerca de la relación entre ministros y fieles. En el segundo, las diferentes designaciones que recibe Pablo en (...) el capítulo evidenciarían no solo la compleja identidad de los creyentes, sino la propuesta comunitaria del autor. (shrink)
