Deep Reinforcement Learning Hands-On: Apply modern RL methods to practical problems of chatbots, robotics, discrete optimization, web automation, and more, 2nd Edition 2, Lapan, Maxim, eBook - Amazon.com

#artificialintelligence

RL development is being driven by several companies and research groups, including Google, Microsoft, and Facebook. It requires lots of investment in research, as there are not that many directions that are developed enough to be able to just take their methods and apply them to a problem. This is similar to how natural language processing and computer vision were several years ago. Having said that, the field of RL is attracting lots of attention, both from researchers and practitioners. This book helps readers to understand RL methods using real-life problems, and make the exciting RL domain accessible to a much wider audience than just research groups or large AI companies.

"In the past few years, our tolerance of sloppy thinking has led us to repeat many mistakes over and over. If we are to retain any credibility, this should stop. It is hard to say where [we] have gone wronger, in underestimating language or overestimating computer programs." In April, Open AI released a neural network model called DALL-E 2 that blew people's minds; last week a new model came out from Google Brain called Imagen, and it was even better. Both turn sentences into art, and even a hardened skeptic like myself can't help but be amazed.


The Future Of AI: Careers In Machine Learning - AI Summary

#artificialintelligence

Machine learning is a branch of data science which involves using "data science programs that can adapt based on experience," said Ben Tasker, technical program facilitator of data science and data analytics at Southern New Hampshire University. As the fields of science and engineering continue to advance, artificial intelligence is becoming "a lot less artificial and a lot more intelligent," Tasker said. Because so much about the field of data science in general and AI in particular is new, there are many opportunities to "make your own niche, especially now that many companies have started to invest in the idea of artificial intelligence," Tasker said. AI Engineer: In this role, one may be involved in the different facets of designing, developing and building artificial intelligence models using machine learning algorithms. Big Data Engineer: Overlapping with the role of a data scientist, the person in this role analyzes a company's volume of data known as "big data," and then uses the analyses to mine useful information in support of the company and its business model.


Results of Deep Funding -- Round 1

#artificialintelligence

This marks a new phase in the SingularityNET ecosystem, where we will foster the growth of the platform by supporting projects with AGIX tokens, knowledge and experience. We are very happy to present the projects that have been selected by our engaged community to be awarded with their requested amounts. While the portal was open, a total of 47 proposals were submitted for the $1million worth of AGIX token treasury funds, which made this round a fair success! After reviewing the proposals on their formal compliance to the Deep Funding rules, only 28 made it to the voting round. All of these 28 had more than the required 1% of cast votes, but only a minority of 12 proposals received an average grade of 6,5 or higher.


AI in the cloud pays dividends for Liberty Mutual

#artificialintelligence

Liberty Mutual is one of the most experienced and advanced cloud adopters in the nation. And that is in no small part thanks to the vision of James McGlennon, who in his role as CIO of Liberty Mutual for past 17 years has led the charge to the cloud, analytics, and AI with a budget north of $2 billion. Eight years ago, McGlennon hosted an off-site think tank with his staff and came up with a "technology manifesto document" that defined in those early days the importance of exploiting cloud-based services, becoming more agile, and instituting cultural changes to drive the company's digital transformation. Today, Liberty Mutual, which has 45,000 employees across 29 countries, has a robust hybrid cloud infrastructure built primarily on Amazon Web Services but with specific uses of Microsoft Azure and, lesser so, Google Cloud Platform. Liberty Mutual's cloud infrastructure runs an array of business applications and analytics dashboards that yield real-time insights and predictions, as well as machine learning models that streamline claims processing.


Backpropagation! Propagating the info back to you!

#artificialintelligence

To unlock the mystical blackbox of backpropagation, for new machine learning enthusiasts, I've created this short analogy. To use an everyday analogy, we'll consider cooking your favorite food!! To cook your favorite food, you'll need ingredients. To get/buy your ingredients, you'll need money. The amount of money you're willing to spend (budget) influences how much you can spend on your ingredients, and the amount of ingredients you have would determine how many portions of your favorite food that you can prepare.


Gato, the latest from Deepmind. Towards true AI?

#artificialintelligence

The deep learning field is progressing rapidly, and the latest work from Deepmind is a good example of this. Their Gato model is able to learn to play Atari games, generate realistic text, process images, control robotic arms, and more, all with the same neural network. Inspired by large-scale language models, Deepmind applied a similar approach but extended beyond the realm of text outputs. This new AGI (after Artificial General Intelligence) works as a multi-modal, multi-task, multi-embodiment network, which means that the same network (i.e. a single architecture with a single set of weights) can perform all tasks, despite involving inherently different kinds of inputs and outputs. While Deepmind's preprint presenting Gato is not very detailed, it is clear enough in that it is strongly rooted in transformers as used for natural language processing and text generation.


Think you can spot content written by AI? The truth is you've probably already read a lot of it

#artificialintelligence

Two years ago this weekend, GPT-3 was introduced to the world. You may not have heard of GPT-3, but there's a good chance you've read its work, used a website that runs its code, or even conversed with it through a chatbot or a character in a game. GPT-3 is an AI model -- a type of artificial intelligence -- and its applications have quietly trickled into our everyday lives over the past couple of years. In recent months, that trickle has picked up force: more and more applications are using AI like GPT-3, and these AI programs are producing greater amounts of data, from words, to images, to code. A lot of the time, this happens in the background; we don't see what the AI has done, or we can't tell if it's any good.


Summary: Class-incremental Learning via Deep Model Consolidation

#artificialintelligence

Class incremental learning or continual learning is referred to where we want our system to learn a new set of classes without forgetting any prior knowledge of old classes which makes it a challenging problem. It's what we call a general-purpose AI system and it's close to how we human learns. We use our prior knowledge to learn a new task quickly without forgetting any prior knowledge. Learning on a novel set of classes results in catastrophic forgetting- an abrupt degradation of performance on the original set of classes when the training objective is adapted to a newly added set of classes. Let's start with the model architecture and understand how the proposed method is applied to incremental learning tasks- The idea is based on the assumption that natural images lie on a low-dimensional manifold so we can utilize the easily available unlabeled data from the same domain to approximate the target distribution.


Can AI Identify Patients With Long COVID?

#artificialintelligence

Long COVID refers to the condition where people experience long-term effects from their infection with the SARS CoV-2 virus that is responsible for the COVID-19 disease (Coronavirus disease 2019) pandemic according to the U.S. Centers for Disease Control and Prevention (CDC). A new study published in The Lancet Digital Health applies artificial intelligence (AI) machine learning to identify patients with long COVID-19 using data from electronic health records with high accuracy. "Patients identified by our models as potentially having long COVID can be interpreted as patients warranting care at a specialty clinic for long COVID, which is an essential proxy for long COVID diagnosis as its definition continues to evolve," the researchers concluded. "We also achieve the urgent goal of identifying potential long COVID in patients for clinical trials." Globally there have been over 510 million confirmed cases of COVID-19 and more than 6.2 million deaths according to April 2022 statistics from Johns Hopkins University.
