This document provides an overview of cognitive design for artificial minds. It discusses how cognitive artificial systems are inspired by human and natural cognition. The key points made are:
- Cognitive artificial systems are inspired by human and natural cognition to be more general and versatile than standard AI systems.
- Examples of cognitively inspired AI systems include ACT-R, Soar, and systems developed using the subsumption architecture.
- Cognitively inspired systems differ from standard AI in that they aim to have explanatory power for human cognition through structural models of cognitive processes and representations.
- Such systems can be used to test cognitive theories, provide human-like capabilities, and potentially lead to more general artificial intelligence.

Computational Explanation in Biologically Inspired Cognitive Architectures/Sy...Antonio Lieto
Computational models of cognition can have explanatory power when they are structurally valid models of the natural systems that inspired them. The document discusses different approaches to modeling knowledge in cognitive architectures and humans. It analyzes how ACT-R, CLARION, and LIDA represent concepts, and suggests that humans likely use heterogeneous representations including prototypes, exemplars, and other conceptual structures. Models should account for this heterogeneity to better explain human cognition.
Towards which Intelligence? Cognition as Design Key for building Artificial I...Antonio Lieto
The document discusses approaches to building artificial intelligence systems based on human cognition. It argues that AI should focus on high-level cognitive functions like humans exhibit full intelligence. A cognitive AI approach models heuristics and bounded rationality used by humans. The document presents a case study of a common sense reasoning system that integrates heterogeneous conceptual representations like prototypes and exemplars, and uses a dual process of reasoning. The system is evaluated against human responses in categorization tasks with 84% accuracy, providing insights to refine the cognitive theory.
The document discusses several topics related to artificial intelligence including definitions of intelligence and AI, approaches to AI like symbolic AI and biological AI, applications of AI such as expert systems and game playing, and techniques like the Turing test. It also provides a brief history of AI from 1943 to the present day and discusses components of AI programs like knowledge bases, control strategies, and inference mechanisms.

Universal Artificial Intelligence for Intelligent Agents: An Approach to Supe...IOSR Journals
This document proposes a methodology to develop intelligent agents with universal artificial intelligence (UAI) that can operate effectively in new environments. The methodology uses a neuro-fuzzy system combined with a hidden Markov model (HMM) to provide agents with learning capabilities and the ability to make decisions in unknown environments. The neuro-fuzzy system would extract fuzzy rules and membership functions from data to guide an agent. The HMM would generate sequences of sensed states to model dynamic environments. This approach aims to create "super intelligent agents" that can perform human-level tasks in any computable environment without reprogramming. A literature review found that neuro-fuzzy and HMM methods have been successfully used for mobile robot obstacle avoidance and human motion recognition.

Although artificial intelligence (AI) is currently one of the most interesting areas in scientific research, the potential threats posed by emerging AI systems remain a source of persistent controversy. To address the issue of AI threat,this study proposes
a “standard intelligence model” that unifies AI and human characteristics in terms of
four aspects of knowledge, i.e., input, output, mastery, and creation. Using this model, we observe three challenges, namely, expanding of the von Neumann architecture;
testing and ranking the intelligence quotient (IQ) of naturally and artificially intelligent systems, including humans, Google, Microsoft’s Bing, Baidu, and Siri; and
finally, the dividing of artificially intelligent systems into seven grades from robots to Google Brain. Based on this, we conclude that Google’s AlphaGo belongs to the third grade.

We claim that Conceptual Spaces offer a lingua franca that allows to unify and generalize many aspects of the symbolic, sub-symbolic and diagrammatic approaches (by overcoming some of their typical problems) and to integrate them on a common ground. In doing so we extend and detail some of the arguments explored by Gardenfors [23] for defending the need of a conceptual, intermediate, representation level between
the symbolic and the sub-symbolic one. Additionally, we argue that Conceptual Spaces could offer a unifying framework for interpreting many kinds of diagrammatic and analogical representations. As a consequence, their adoption could also favor the integration of diagrammatical representation and

A Computational Framework for Concept Representation in Cognitive Systems and...Antonio Lieto
This document proposes a framework for representing concepts in cognitive systems called "concepts as heterogeneous proxytypes". It suggests concepts have multiple representations, including classical, prototypical, exemplar-based and theory-based. These representations are stored separately but can be combined. The framework represents concepts computationally using different frameworks like symbols, conceptual spaces and neural networks. It aims to test if this heterogeneous proxytype hypothesis can explain human concept identification and retrieval by implementing it in cognitive architectures.
This document describes a case study using ontological representations and narrative to explore cultural heritage archives. The Labyrinth project uses an ontology modeling narrative elements like stories, actions, characters to allow users to navigate a digital archive. The ontology relates these narrative aspects to archive items. Reasoning over the ontology transfers narrative properties to items, allowing exploration by story or action. A user study will evaluate if this approach supports serendipitous discovery and new learning experiences within cultural heritage archives.
Riga2013 Symposium on Concepts and PerceptionAntonio Lieto
This document discusses the relationship between concepts and perception through the lens of dual process theory. It analyzes different perspectives on the nature of concepts, such as prototype theory and exemplar theory, and proposes that concepts involve both System 1 implicit processes and System 2 explicit processes. System 1 processes are related to perception and involve fast, automatic categorization based on prototypes. In contrast, System 2 processes are slower, more controlled processes like monotonic categorization. The document concludes that understanding the heterogeneous nature of concepts, including both System 1 and System 2 aspects, can provide insight into the complex relationship between concepts and perception.

Cosa hanno in comune un mattoncino Lego e la backdoor XZ?Speck&Tech
ABSTRACT: A prima vista, un mattoncino Lego e la backdoor XZ potrebbero avere in comune il fatto di essere entrambi blocchi di costruzione, o dipendenze di progetti creativi e software. La realtà è che un mattoncino Lego e il caso della backdoor XZ hanno molto di più di tutto ciò in comune.

Why?
Humans (and/or other natural systems) are still,
by far, the best unmatched systems able to solve
a wide-range of problems
6. From Human to Artificial Cognition (and
back)

Inspiration
Explanation
8. Cybernetics tradition of the AI
This approach to the study of the artificial borrowed its original inspiration – from a
historical perspective– from the methodological apparatus developed by the scholars in
Cybernetics.
1948 book of Norbert Wiener entitled “Cybernetics: Or Control and Communication
in the Animal and the Machine”.
One of underlying idea of cybernetics was that one of building mechanical models to
simulate the adaptive behavior of natural systems.
(Cordeschi, 2002): “the fundamental insight of cybernetics was in the the proposal of
a unified study of organisms and machines”.

has an explanatory power w.r.t. the natural system taken as source of
inspiration ?

11. Wiener’s “Paradox”
“The best material model of a cat is another or possibly the same cat” (Rosenblueth &
Wiener, ’45)
12. A Design Problem
Z.Pylyshyn (’79): “if we do not formulate any restriction about a model
we obtain the functionalism of a Turing machine. If we apply all the
possible restrictions we reproduce a whole human being”
• A design perspective: between the explanatory level of
functionalism (based on the macroscopic stimulus-response
relationship) and the mycroscopic one of fully structured models
(reductionist materialism) we have, in the middle, a lot of possible
structural models.

15. Take home message (part 1)
• Cognitive Artificial Models have an explanatory power
only if they are structurally valid models (realizable in
different ways and empirically adequate).
• Cognitive Artificial Systems built with this design
perspective have an explanatory role for the theory
they implement and the “computational experiment”
can provide results useful for refining of rethinking
theoretical aspects of the natural inspiring system.

qualitative analysis about the cognitive adequacy and the human-like performances of
artificial systems in both single and multi-tasking settings.” (Lieto, 2021)

41. Linda Problem

A version of the Linda example:
-Linda was young in the ‘70s
-Linda likes the color red
-Linda graduated in philosophy
- Linda is against nuclear power (“green” person)
Linda
Linda is a bankteller
Linda is a feminist and
bankteller
42. Evolutionary shaped heuristics
19
The conjunction fallacy can be interpreted as an example of the strong
tendency of human subjects to resort to prototypical information in
categorization (Non Monotonic Categorization)
A version of the Linda example:
-Pippo weights 200 Kg
-Pippo is 2 metres tall
-Pippo growls and roars
-Pippo has robust teeths
Pippo is a mammal
Pippo is a mammal and is wild
and dangerous

47. Cash register
At the computational level, the functioning of the register can be accounted for in terms
of arithmetic (e.g. in terms of the theory of addition): at this level are relevant the
computed function (addition), and such abstract properties of it, as commutativity or
associativity (Marr 1982, p. 23).
The level of representation and algorithm specify the form of the representations and
the processes elaborating them: “we might choose Arabic numerals for the
representations, and for the algorithm we could follow the usual rules about adding the
least significant digits first and `carrying' if the sum exceeds 9” (ibid.).
Finally, the level of implementation has to do with how such representations and
processes are physically realized; for example, the digits could be represented as positions
on a metal wheel, or, alternatively, as binary numbers coded by the electrical states of
digital circuitry

54. Other problems
• Cannot learn new knowledge (costs for retraining
unfeasible from a computational, environmental, and
economic point of view.)
• “catastrophic interference” problem: new knowledge
overwrites (rather than integrates) knowledge already
distributed in such network models.
• Integration

59. Cognitive Architectures
59
Allen Newell (1990)
Unified Theory of Cognition
A cognitive architecture (Newell, 1990) implements the invariant
structure of the cognitive system.
The work on such systems started in the ‘80s (SOAR (Newell,
Laird and Rosenbloom, 1982)
It captures the underlying commonality between different
intelligent agents and provides a framework from which
intelligent behavior arises.
The architectural approach emphasizes the role of memory in the
cognitive process.

Composed by different integrated modules which
are coordinated by means of a centralised
prodoction rules system
Each module communicates with the others through
its own buffers (a sort of micro-specialized working
memories) and the central system selects its next
actions by taking into account the buffer content

101. Summing up…and looking ahead
• Behavioral performances are not sufficient to ascribe cognitive
faculties to AI systems (see Minimal Cognitive Grid)
• Behavioral tests (e.g. Turing Test) don’t say very much about the
actual “intelligence” of a system
• In real world contexts, the gap between natural and artificial
intelligence is still enormous
• Models working on the challenge of integrated intelligence will
play a major role for the development of AI technologies and for
the understanding of mental phenomena.
• Time seems mature now for a renewed collaboration between 2
“sciences of the artificial”: AI and Cognitive Science
