Could AI Democratise Education? Socio-Technical Imaginaries of an EdTech Revolution

#artificialintelligence

Artificial Intelligence (AI) in Education has been said to have the potential for building more personalised curricula, as well as democratising education worldwide and creating a Renaissance of new ways of teaching and learning. Millions of students are already starting to benefit from the use of these technologies, but millions more around the world are not. If this trend continues, the first delivery of AI in Education could be greater educational inequality, along with a global misallocation of educational resources motivated by the current technological determinism narrative. In this paper, we focus on speculating and posing questions around the future of AI in Education, with the aim of starting the pressing conversation that would set the right foundations for the new generation of education that is permeated by technology. This paper starts by synthesising how AI might change how we learn and teach, focusing specifically on the case of personalised learning companions, and then move to discuss some socio-technical features that will be crucial for avoiding the perils of these AI systems worldwide (and perhaps ensuring their success).

First to Launch Coding, Robotics Courses in Govt Schools, Goa Sets Example for All States

#artificialintelligence

In a move that aims to benefit 65,600 students and 540 teachers from government and government-aided schools in Goa, the State government in March this year implemented its novel and first of its kind in India – Coding and Robotics Education in Schools Scheme from the academic year 2021-22. The scheme aims to incorporate computational and design thinking abilities, as well as programming, into the Goa state board curriculum to prepare students to the needs of the digital world in the 21st century. It was introduced by Chief Minister Dr Pramod Sawant, who is also the Minister of Education. The State government is looking to make this sort of skill education (coding and problem solving skills) accessible to school-going children from all sections of society. This scheme is a collaborative effort of the Directorate of Technical Education (DTE), Directorate of Education, State Council Educational Research and Training (SCERT) and industry experts.


What is PyTorch? - PyImageSearch

#artificialintelligence

By the end of this tutorial, you'll have a good introduction to the PyTorch library and be able to discuss the pros and cons of the library with other deep learning practitioners. To learn about the PyTorch deep learning library, just keep reading. PyTorch is an open source machine learning library that specializes in tensor computations, automatic differentiation, and GPU acceleration. For those reasons, PyTorch is one of the most popular deep learning libraries, competing with both Keras and TensorFlow for the prize of "most used" deep learning package: PyTorch tends to be especially popular among the research community due to its Pythonic nature and ease of extendability (i.e., implementing custom layer types, network architectures, etc.). In this tutorial, we'll discuss the basics of the PyTorch deep learning library.


Reinforcement Learning for Everybody

#artificialintelligence

As with many other machine learning, or more generally, AI problems, RL can also be intimidating if one starts directly from the full problem and the formal mathematical definitions, so let us start by loosely defining RL as a collection of both problems and representations, meaning that, we have both RL problems and RL methods to solve that class of problems. More formally, when we are working on a reinforcement learning problem, we are trying to map specific situations to an action or a set of actions, and each of those actions will have a consequence or a "reward" which can be either positive, neutral, or negative, in fact, this can simply be a real number. For example, let's say that we have a pet monkey called Marcel and that he has a set of toys that he loves to play with, and let's say that we want to teach Marcel to pee in the toilet as opposed to on the floor, so to incentivize Marcel too choose the right action, we'll give him a new toy every time he pees in the toilet ( 1 toy) and we'll remove a toy from his collection (-1 toy) every time he pees on the floor. In this case, hopefully, Marcel (we can call him the "agent"), will learn to select an "action" (pee on the floor vs pee in the toilet) whenever he finds himself in a given situation or "state" -- when he feels the need to pee -- in a way to maximize the number of toys, namely the rewards, by choosing the right actions at that state. Now, I want to emphasize that while this example does a decent job describing the general idea of a reinforcement learning problem, there are many elements missing to fully describe the RL problem.


Application of Artificial Intelligence and Machine Learning in Libraries: A Systematic Review

arXiv.org Artificial Intelligence

As the concept and implementation of cutting-edge technologies like artificial intelligence and machine learning has become relevant, academics, researchers and information professionals involve research in this area. The objective of this systematic literature review is to provide a synthesis of empirical studies exploring application of artificial intelligence and machine learning in libraries. To achieve the objectives of the study, a systematic literature review was conducted based on the original guidelines proposed by Kitchenham et al. (2009). Data was collected from Web of Science, Scopus, LISA and LISTA databases. Following the rigorous/ established selection process, a total of thirty-two articles were finally selected, reviewed and analyzed to summarize on the application of AI and ML domain and techniques which are most often used in libraries. Findings show that the current state of the AI and ML research that is relevant with the LIS domain mainly focuses on theoretical works. However, some researchers also emphasized on implementation projects or case studies. This study will provide a panoramic view of AI and ML in libraries for researchers, practitioners and educators for furthering the more technology-oriented approaches, and anticipating future innovation pathways.


Unsupervised Domain Adaptation for Semantic Image Segmentation: a Comprehensive Survey

arXiv.org Artificial Intelligence

Semantic segmentation plays a fundamental role in a broad variety of computer vision applications, providing key information for the global understanding of an image. Yet, the state-of-the-art models rely on large amount of annotated samples, which are more expensive to obtain than in tasks such as image classification. Since unlabelled data is instead significantly cheaper to obtain, it is not surprising that Unsupervised Domain Adaptation reached a broad success within the semantic segmentation community. This survey is an effort to summarize five years of this incredibly rapidly growing field, which embraces the importance of semantic segmentation itself and a critical need of adapting segmentation models to new environments. We present the most important semantic segmentation methods; we provide a comprehensive survey on domain adaptation techniques for semantic segmentation; we unveil newer trends such as multi-domain learning, domain generalization, test-time adaptation or source-free domain adaptation; we conclude this survey by describing datasets and benchmarks most widely used in semantic segmentation research. We hope that this survey will provide researchers across academia and industry with a comprehensive reference guide and will help them in fostering new research directions in the field.


Lecture Notes on Partially Known MDPs

arXiv.org Artificial Intelligence

In these notes we will tackle the problem of finding optimal policies for Markov decision processes (MDPs) which are not fully known to us. Our intention is to slowly transition from an offline setting to an online (learning) setting. Namely, we are moving towards reinforcement learning. As a reminder, a (stationary) MDP M is a 4-tuple (S,A,P,r) where: - S is a finite set of states, - A is a finite set of actions. For intuition, this is just a graph-based way of saying that the reachable part of the Markov chain induced by the policy has a single closed communicating class. Let M be a communicating MDP and i one of its states.


Is Class-Incremental Enough for Continual Learning?

arXiv.org Artificial Intelligence

The ability of a model to learn continually can be empirically assessed in different continual learning scenarios. Each scenario defines the constraints and the opportunities of the learning environment. Here, we challenge the current trend in the continual learning literature to experiment mainly on class-incremental scenarios, where classes present in one experience are never revisited. We posit that an excessive focus on this setting may be limiting for future research on continual learning, since class-incremental scenarios artificially exacerbate catastrophic forgetting, at the expense of other important objectives like forward transfer and computational efficiency. In many real-world environments, in fact, repetition of previously encountered concepts occurs naturally and contributes to softening the disruption of previous knowledge. We advocate for a more in-depth study of alternative continual learning scenarios, in which repetition is integrated by design in the stream of incoming information. Starting from already existing proposals, we describe the advantages such class-incremental with repetition scenarios could offer for a more comprehensive assessment of continual learning models.
