Partial Information Sharing over Social Learning Networks

arXiv.org Artificial Intelligence

This work addresses the problem of sharing partial information within social learning strategies. In traditional social learning, agents solve a distributed multiple hypothesis testing problem by performing two operations at each instant: first, agents incorporate information from private observations to form their beliefs over a set of hypotheses; second, agents combine the entirety of their beliefs locally among neighbors. Within a sufficiently informative environment and as long as the connectivity of the network allows information to diffuse across agents, these algorithms enable agents to learn the true hypothesis. Instead of sharing the entirety of their beliefs, this work considers the case in which agents will only share their beliefs regarding one hypothesis of interest, with the purpose of evaluating its validity, and draws conditions under which this policy does not affect truth learning. We propose two approaches for sharing partial information, depending on whether agents behave in a self-aware manner or not. The results show how different learning regimes arise, depending on the approach employed and on the inherent characteristics of the inference problem. Furthermore, the analysis interestingly points to the possibility of deceiving the network, as long as the evaluated hypothesis of interest is close enough to the truth.


LISA: Learning Interpretable Skill Abstractions from Language

arXiv.org Artificial Intelligence

Learning policies that effectively utilize language instructions in complex, multi-task environments is an important problem in sequential decision-making. While it is possible to condition on the entire language instruction directly, such an approach could suffer from generalization issues. In our work, we propose \emph{Learning Interpretable Skill Abstractions (LISA)}, a hierarchical imitation learning framework that can learn diverse, interpretable primitive behaviors or skills from language-conditioned demonstrations to better generalize to unseen instructions. LISA uses vector quantization to learn discrete skill codes that are highly correlated with language instructions and the behavior of the learned policy. In navigation and robotic manipulation environments, LISA outperforms a strong non-hierarchical Decision Transformer baseline in the low data regime and is able to compose learned skills to solve tasks containing unseen long-range instructions. Our method demonstrates a more natural way to condition on language in sequential decision-making problems and achieve interpretable and controllable behavior with the learned skills.


How Machine Learning Can Benefit Online Learning

#artificialintelligence

From phones to watches to TVs, everything around us is becoming'smart'. Education is not so far behind. The'smart' approach to education is typically the incorporation of Machine Learning (ML) in learning and development. Machine Learning leverages Artificially Intelligent methods to teach systems how to make informed decisions without any human intervention. This is done by feeding data to a machine learning algorithm which is then able to process the data and make inferences for future events.


Introduction to Deep Learning

#artificialintelligence

Deep Learning is the go-to technique for many applications, from natural language processing to biomedical. Deep learning can handle many different types of data such as images, texts, voice/sound, graphs and so on. This course will cover the basics of DL including how to build and train multilayer perceptron, convolutional neural networks (CNNs), recurrent neural networks (RNNs), autoencoders (AE) and generative adversarial networks (GANs). The course includes several hands-on projects, including cancer detection with CNNs, RNNs on disaster tweets, and generating dog images with GANs. Prior coding or scripting knowledge is required.


Sign Language Recognition using Deep Learning

#artificialintelligence

The goal of this deep learning project is to create a model for sign language recognition using a convolutional neural network (CNN), utilising the Keras package and OpenCV for live picture capture. This Sign Language Recognition (SLR) model follows a vision-based approach, where the features corresponding to the palms, finger position and joint angles are estimated and are then used to perform recognition. This method requires acquiring images of the signs through a camera and processing using image processing techniques. To build the sign language recognition model, MNIST ( Modified National Institute of Standards and Technology) dataset. This dataset consists images of alphabets and numbers, each image having a size of 28x28 pixels which gives a total of 784 pixels per image.


ChatGPT is the dazzling, scary future of AI chatbots

PCWorld

Someone on the Internet wrote that ChatGPT just made the first two years of high-school homework meaningless, and that's not far off. OpenAI's new AI text-generation tool currently offers sophisticated, lengthy and even fun responses to textual prompts, currently all for free. ChatGPT is part Wikipedia, part researcher, part analyst, and part poet. It can write a short paper on the causes and outcomes of the French Revolution. It can write a seven-paragraph essay on why nihilism should be your personal philosophy. It can write an epic poem on the need to brush your teeth regularly.

The Impact of Artificial Intelligence on The Banking Industry

#artificialintelligence

AI can accomplish more with less, from manufacturing to telecommunications to food service. At the same time, it's a powerful tool for companies to meet or exceed consumer expectations. You may not realize that domestic and offshore banks also employ AI in several ways. Two goals drive the desire to make the most of this resource: lower costs while enhancing profits and providing a level of convenience that motivates customer loyalty. Here are some of the ways that AI is changing the way that many banks do business.
