Furthermore, we believe that this theoretical base should perform and automate tasks in dynamic environments and in allow new functionalities to evolve hierarchically just like close or direct interaction with humans. Uncertainty about software libraries build on top of each other. We believe so the environment and complexity of the tasks require robots since this would allow the discussions and development to with the ability to reason and plan while being reactive flourish at different levels of abstractions, and allow for better to changes in their environment. To achieve such behavior, synergy with other research fields.


Why My Cognitive Science Degree Was A Great Foundation For Data Science and Machine Learning

#artificialintelligence

I had endless curiosity and excitement -- doe-eyed and optimistic. But ringing in the back of my mind was the insecurity that I didn't come from any of the traditional backgrounds, for example, computer science, statistics, or business. Instead, I graduated with a bachelor's in cognitive science. However, as time passed and my experience grew, an idea began to slowly unravel -- perhaps, my background provided a much more solid foundation than I had initially anticipated. "Cognitive Science is an interdisciplinary field of neuroscience, artificial intelligence, computer science, philosophy, psychology, linguistics, and anthropology."


A Survey on Hyperdimensional Computing aka Vector Symbolic Architectures, Part I: Models and Data Transformations

arXiv.org Artificial Intelligence

This two-part comprehensive survey is devoted to a computing framework most commonly known under the names Hyperdimensional Computing and Vector Symbolic Architectures (HDC/VSA). Both names refer to a family of computational models that use high-dimensional distributed representations and rely on the algebraic properties of their key operations to incorporate the advantages of structured symbolic representations and vector distributed representations. Notable models in the HDC/VSA family are Tensor Product Representations, Holographic Reduced Representations, Multiply-Add-Permute, Binary Spatter Codes, and Sparse Binary Distributed Representations but there are other models too. HDC/VSA is a highly interdisciplinary area with connections to computer science, electrical engineering, artificial intelligence, mathematics, and cognitive science. This fact makes it challenging to create a thorough overview of the area. However, due to a surge of new researchers joining the area in recent years, the necessity for a comprehensive survey of the area has become extremely important. Therefore, amongst other aspects of the area, this Part I surveys important aspects such as: known computational models of HDC/VSA and transformations of various input data types to high-dimensional distributed representations. Part II of this survey is devoted to applications, cognitive computing and architectures, as well as directions for future work. The survey is written to be useful for both newcomers and practitioners.


An Algorithmic Theory of Metacognition in Minds and Machines

arXiv.org Artificial Intelligence

Humans sometimes choose actions that they themselves can identify as sub-optimal, or wrong, even in the absence of additional information. How is this possible? We present an algorithmic theory of metacognition based on a well-understood trade-off in reinforcement learning (RL) between value-based RL and policy-based RL. To the cognitive (neuro)science community, our theory answers the outstanding question of why information can be used for error detection but not for action selection. To the machine learning community, our proposed theory creates a novel interaction between the Actor and Critic in Actor-Critic agents and notes a novel connection between RL and Bayesian Optimization. We call our proposed agent the Metacognitive Actor Critic (MAC). We conclude with showing how to create metacognition in machines by implementing a deep MAC and showing that it can detect (some of) its own suboptimal actions without external information or delay.

Cognitive Computing

#artificialintelligence

What is meant by the term Cognitive computing? It is one of the most interesting and exciting thing to know about in the present world. This post is consists of the features of cognitive computing and its brief explanation. Does the decision taken by cognitive computing is similar to human decision making process. Conventional computing solutions based on the math principles that emanate from 1940's are programmed based on rules and logic intend to derive math by precise answers. Human takes decision in four steps.


Learning a Metacognition for Object Detection

arXiv.org Artificial Intelligence

In contrast to object recognition models, humans do not blindly trust their perception when building representations of the world, instead recruiting metacognition to detect percepts that are unreliable or false, such as when we realize that we mistook one object for another. We propose METAGEN, an unsupervised model that enhances object recognition models through a metacognition. Given noisy output from an object-detection model, METAGEN learns a meta-representation of how its perceptual system works and uses it to infer the objects in the world responsible for the detections. METAGEN achieves this by conditioning its inference on basic principles of objects that even human infants understand (known as Spelke principles: object permanence, cohesion, and spatiotemporal continuity). We test METAGEN on a variety of state-of-the-art object detection neural networks. We find that METAGEN quickly learns an accurate metacognitive representation of the neural network, and that this improves detection accuracy by filling in objects that the detection model missed and removing hallucinated objects. This approach enables generalization to out-of-sample data and outperforms comparison models that lack a metacognition. Learning accurate representations of the world is critical for prediction, inference, and planning in complex environments (Lake et al., 2017). In human vision, these representations are generated by a perceptual system that transforms light entering the retina into representations of the physical space and the objects in it (Kar & DiCarlo, 2021; Güçlü & van Gerven, 2017).


En Route to AI PhD: NSF Fellowship Weeks 0–5

#artificialintelligence

October 4, 2021: This post is a bit of a rush-up recap of the last month or so since this period of my life began. Finding out about the fellowship was a late-August surprise, after an unassuming email notification. I still remember Orthogonal Research and Education Lab PI, Dr Bradly Alicea for his letter of recommendation months ago. August was also my first month after moving to Boston, following a whirlwind of a summer abroad on a bit of travel, new jobs, research, and maybe "a week of vacation in London surrounding a business trip to Oxford." It was also exciting to be lead organizer and co-host for the Discussion Group at CogSci 2021 "Trajectories in Cognitive Science", as well as participate in a slew of other connference activity at OREL. Seeing Boston at the end of summer, and finding I know many colleagues, academic, general nerds, and friends here already, was a treat.


Natural Computational Architectures for Cognitive Info-Communication

arXiv.org Artificial Intelligence

Recent comprehensive overview of 40 years of research in cognitive architectures, (Kotseruba and Tsotsos 2020), evaluates modelling of the core cognitive abilities in humans, but only marginally addresses biologically plausible approaches based on natural computation. This mini review presents a set of perspectives and approaches which have shaped the development of biologically inspired computational models in the recent past that can lead to the development of biologically more realistic cognitive architectures. For describing continuum of natural cognitive architectures, from basal cellular to human-level cognition, we use evolutionary info-computational framework, where natural/ physical/ morphological computation leads to evolution of increasingly complex cognitive systems. Forty years ago, when the first cognitive architectures have been proposed, understanding of cognition, embodiment and evolution was different. So was the state of the art of information physics, bioinformatics, information chemistry, computational neuroscience, complexity theory, self-organization, theory of evolution, information and computation. Novel developments support a constructive interdisciplinary framework for cognitive architectures in the context of computing nature, where interactions between constituents at different levels of organization lead to complexification of agency and increased cognitive capacities. We identify several important research questions for further investigation that can increase understanding of cognition in nature and inspire new developments of cognitive technologies. Recently, basal cell cognition attracted a lot of interest for its possible applications in medicine, new computing technologies, as well as micro- and nanorobotics.
