Quantum Structures in Human Decision-making: Towards Quantum Expected Utility
Daniel Kahneman was awarded the Nobel Prize in Economic Science in 2002 for his pioneering studies on the identification and estimation of the psychological factors that influence human behaviour under uncertainty, which led to the birth of a new domain called behavioural economics. Cognitive psychologists have assumed for years, often implicitly, that complex cognitive processes, like human judgement and decision-making (DM), have to be modelled by combining set-theoretic structures and should obey to mathematical relations that resemble those typically used in logic, formalized by Boole (Boolean logic), and probability, axiomatized by Kolmogorov (Kolmogorovian probability) [1]. These structures are known in physics as classical structures: they were originally used in classical physics, and later extended to statistics, psychology, economics, finance and computer science. Classical structures are also implicitly assumed in the so-called Bayesian approach, according to which any source of uncertainty can be formalized probabilistically, while people update knowledge according to the Bayes law of Kolmogorovian probability. Finally, classical structures are the building blocks of subjective expected utility theory (SEUT), providing both the descriptive and the normative foundations of rational DM: in situations of uncertainty, people (should) choose as if they maximized EU with respect to a unique probability measure, satisfying the axioms of Kolmogorov and interpreted as their subjective probability [2, 3]. However, on the one side, empirical research in cognitive psychology has revealed that classical structures are not generally able to model human judgements and decisions, thus making problematical the 1 interpretation of a wide range of cognitive phenomena in terms of standard logic and probability theory. On the other side, Kahneman, Tversky and other authors suggested that these empirical deviations from classicality are "true errors" of human reasoning, whence the use of terms like "effect", "fallacy", "paradox", "contradiction", etc., to refer to such phenomena [4, 5].
The Dawn of Cognitive Factories: Artificial Intelligence in the Shop Floor
Karthik Sundaram, Program Manager-The Industrial Internet of Things, Frost & Sullivan โ an excerpt from SPS IPC Drives 2018 presentation to be delivered 28th of November 2018 at 2.00-2.30 Situated in a mountain village of Japan is FANUC's widely reported lights out factory. This one of a kind, unmanned factory works autonomously 24/7 and is well known for robots that can assemble, test, and monitor themselves. A few decades ago, such a scenario would have existed only in the pages of Isaac Asimov's science fiction. Today, the FANUC use case is a proof of the dawn of cognitive factories and how far artificial intelligence (AI) has been able to penetrate into the walls of these factories.
Top 10 Best Artificial Intelligence Masters Degree Programs in the World
In spite of the fact that the idea of Artificial Intelligence has been around for a long time, it is just in the most recent years that it has gotten on the tech charts and is trending in each and every industry conceivable. Getting to be noticeably extraordinary compared to other cherished techs among the ingenious minds all over the world, Artificial Intelligence demands a mix of computer science, mathematics, cognitive psychology, and engineering. There is no doubt about that soon the demand for experts prepared in Artificial Intelligence would beat supply. In spite of the fact that there is some overlap of Artificial Intelligence with analytics, a capable Artificial Intelligence expert would have profound knowledge on spheres like computer vision, natural language processing, robotics automation, and machine learning. Artificial Intelligence education is still in its youthful days.
You Aren't So Smart: Cognitive Biases are Making Sure of It
According to Wikipedia, cognitive biases "are tendencies to think in certain ways that can lead to systematic deviations from a standard of rationality or good judgment, and are often studied in psychology and behavioral economics." Far more than simply an exercise in academia, cognitive biases have all sorts of practical impacts on our lives, whether or not we admit it. A very broad umbrella, cognitive bias comes in many forms, as evidenced by the fact that Wikipedia lists over 170 of them. Some of these biases are more prevalent in certain areas of life than in others. Below is an infographic from Business Insider, of all places, which is an elementary summary of what it refers to as "20 cognitive biases that screw up your decisions." But how do these cognitive biases relate to real life?
Learning Cognitive Models using Neural Networks
Chaplot, Devendra Singh, MacLellan, Christopher, Salakhutdinov, Ruslan, Koedinger, Kenneth
A cognitive model of human learning provides information about skills a learner must acquire to perform accurately in a task domain. Cognitive models of learning are not only of scientific interest, but are also valuable in adaptive online tutoring systems. A more accurate model yields more effective tutoring through better instructional decisions. Prior methods of automated cognitive model discovery have typically focused on well-structured domains, relied on student performance data or involved substantial human knowledge engineering. In this paper, we propose Cognitive Representation Learner (CogRL), a novel framework to learn accurate cognitive models in ill-structured domains with no data and little to no human knowledge engineering. Our contribution is two-fold: firstly, we show that representations learnt using CogRL can be used for accurate automatic cognitive model discovery without using any student performance data in several ill-structured domains: Rumble Blocks, Chinese Character, and Article Selection. This is especially effective and useful in domains where an accurate human-authored cognitive model is unavailable or authoring a cognitive model is difficult. Secondly, for domains where a cognitive model is available, we show that representations learned through CogRL can be used to get accurate estimates of skill difficulty and learning rate parameters without using any student performance data. These estimates are shown to highly correlate with estimates using student performance data on an Article Selection dataset.
Does machine learning produce mental representations?
Over the last few months, I've been catching up more systematically on what's been happening in machine learning and AI research in the last 5 years or so and noticed that a lot of people are starting to talk about the neural net developing a'mental' representation of the problem at hand. As someone who's preoccupied with mental representations a lot, this struck me as odd because what was being described for the machine learning algorithms did not seem to match what else we know about mental representations. So I've been formulating this post when I was pointed to this interview with Judea Pearl. "That sounds like sacrilege, to say that all the impressive achievements of deep learning amount to just fitting a curve to data. From the point of view of the mathematical hierarchy, no matter how skillfully you manipulate the data and what you read into the data when you manipulate it, it's still a curve-fitting exercise, albeit complex and nontrivial."
Cognitive bias cheat sheet, simplified โ Thinking Is Hard โ Medium
There are 4 qualities of the universe that limit our own intelligence and the intelligence of every other person, collective, organism, machine, alien, or imaginable god. All 200ish of our known biases are attempts to work around these conundrums! The 1st conundrum is that there's too much information in the universe for any individual within the universe to process it all. We have our 5 senses (or up to a dozen depending on how you divide them up), and we're located at points within vast planes of space and time. So there's a lot of information out there (outside your house, across the street, on the other side of the world, throughout the galaxy, and back in time) that we have missed and will continue to miss.
Learning from Exemplars and Prototypes in Machine Learning and Psychology
Zubek, Julian, Kuncheva, Ludmila
This paper draws a parallel between similarity-based categorisation models developed in cognitive psychology and the nearest neighbour classifier (1-NN) in machine learning. Conceived as a result of the historical rivalry between prototype theories (abstraction) and exemplar theories (memorisation), recent models of human categorisation seek a compromise in-between. Regarding the stimuli (entities to be categorised) as points in a metric space, machine learning offers a large collection of methods to select a small, representative and discriminative point set. These methods are known under various names: instance selection, data editing, prototype selection, prototype generation or prototype replacement. The nearest neighbour classifier is used with the selected reference set. Such a set can be interpreted as a data-driven categorisation model. We juxtapose the models from the two fields to enable cross-referencing. We believe that both machine learning and cognitive psychology can draw inspiration from the comparison and enrich their repertoire of similarity-based models.
Google shows how to theoretically control user's behavior based on their data
Two years ago, Google made an internal video that didn't stay internal for long. Recently acquired by The Verge, it tells the speculative story of how the technology giant might develop a universal model of human behavior by collecting as much data from people as possible. The video, titled "The Selfish Ledger," is a thought experiment that shows how a major institution like Google could make use of the complex data profile built up by each person as they buy, browse, and communicate online. Then in true form to tech monoliths' disregard for data privacy, the video suggests the following: What if the ledger could be given a volition or purpose, rather than simply acting as a historical reference? What if we focused on creating a richer ledger by introducing more sources of information? What if we thought of ourselves not as the owners of this information, but as custodians?
