New leadership for MIT-IBM Watson AI Lab

MIT News

An expert in computer vision, machine learning, and human visual perception, Torralba is a professor in the Department of Electrical Engineering and Computer Science and a principal investigator at the Computer Science and Artificial Intelligence Laboratory. "As the inaugural MIT director of our collaboration with IBM, Antonio will closely collaborate with IBM leadership and lab researchers to design and implement the lab's ambitious research agenda," said Chandrakasan, who is also the Vannevar Bush Professor of Electrical Engineering and Computer Science. "I am delighted by the appointment of Antonio Torralba as MIT director of the MIT-IBM Watson AI Lab," said Dario Gil, vice president of AI and IBM Q at IBM Research, who, along with Chandrakasan, oversees the MIT-IBM collaboration. Torralba and the IBM director will lead the MIT-IBM Watson AI Lab, a $240 million investment by IBM in AI efforts over the next 10 years, with $90 million dedicated to supporting MIT research.

5 Ways to Get Started with Reinforcement Learning


Machine learning algorithms, and neural networks in particular, are considered to be the cause of a new AI'revolution'. In this algorithm, the agent learns the quality(Q value) of each action (action is also called policy) based on how much reward the environment gave it. As the agent interacts with the environment, the Q values get updated from random values to values that actually help maximize reward. When training a neural network, data imbalance plays a very important role.

Using AI to Solve Complex Global Supply Chain Management Challenges


Companies are starting to apply artificial intelligence across global supply chain management to improve efficiency, speed and decision-making in areas such as supply chain planning, warehouse automation, and logistics. The SCM World 2016 Future of Supply Chain Survey found that the importance of artificial intelligence has grown rapidly, with 47 percent of supply chain leaders believing the technology is disruptive to global supply chain management strategies.1 Market-research firm IDC predicts that by 2020, 50 percent of mature supply chains will use AI and advanced analytics for planning, and to eliminate sole reliance on short-term demand forecasts.2 Supply chain planning and optimization, including demand forecasting, are among the key areas where AI is already beginning to be deployed. And the volume of data continues to increase, in part due to the trend to connect supply chain management devices to the Internet, according to DHL's 2016 Logistics Trends Radar report.6 Accordingly, companies are already applying AI-based machine learning to automatically analyze vast amounts of supply-chain management data, identify trends, and generate predictive analytics -- the ability to predict problems and outcomes. "Software solutions are beginning to apply machine learning capabilities that can automatically detect errors and make course corrections, while processing real-time data streams," he says.



This is a boon for retailers seeking to accurately predict demand, anticipate customer behavior, and optimize and personalize customer experiences. And as data volumes grow and processing power improves, machine learning becomes increasingly applicable in a wider range of retail areas to further optimize business processes and drive more impactful personalized and contextual consumer experiences and products. But McKinsey has assessed that the U.S. retail sector has only realized 30-40% of the potential margin improvements and productivity growth their analysts envisioned in 2011--and a large share of the value of this growth has gone to consumers through lower prices. So how will AI and machine learning change retail analytics, as they are currently defined?

AI could spot Alzheimer's in MRI scans up to a decade before symptoms show


The AI was trained to correctly spot the difference between diseased and healthy brains, before being tested on its accuracy abilities on a second set of 148 scans – 52 of which were healthy, 48 had Alzheimer's and the other 48 had a mild cognitive impairment that was known to develop into Alzheimer's within 10 years. The algorithm correctly distinguished between healthy and diseased brains 86% of the time, according to the researchers, who added that it was also able to spot the difference between a healthy brain and a mild impairment with an 84% accuracy rating. Last month mobile game Sea Hero Quest – which uses navigation challenges to gather data about spatial movement as part of research into the disease – was expanded to virtual reality for the first time. The game sets users navigation challenges, and they can opt-in to share their data with the researchers behind the game, who can use player performance data to plot spatial navigation skills of different ages groups and genders.

The Impact of AI on Modern Marketing: 50 Categories Ranked, 70 Experts Sound Off MarTechExec


Machine learning, a set of algorithms used by intelligent systems that learn from experience, is an approach to AI that gives marketers the means to take huge amounts of data to build target audiences, personalize messaging and leapfrog potential buyers in their customer journey. The capacity to process a lot of unstructured data will reap massive marketing rewards previously difficult to obtain by marketing professionals themselves. Natural language processing, or NLP, based on machine learning algorithms, is how computers derive meaning from human language. The capacity to process a lot of unstructured data will reap massive marketing rewards previously difficult to obtain by marketing professionals themselves.

Machine Learning Is Making Video Game Characters Smarter And Robots More Competent


So says Danny Lange, the VP of AI and machine learning at Unity Technologies, a major maker of game "engine" software that handles the underlying mechanics of titles like Firewatch and ChronoBlade. Today the company announced Unity Machine Learning Agents--open-source software linking its game engine to machine learning programs such as Google's TensorFlow. It will allow non-playable characters, through trial and error, to develop better, more creative strategies than a human could program, says Lange, using a branch of machine learning called deep reinforcement learning. And Nvidia's new Isaac Lab uses rival Epic Games' Unreal Engine to generate lifelike virtual environments for training the algorithms that control actual robots.

Machine Learning Brings Accuracy to Climate Forecasts


The increasing number of satellites and advancements in climate models has improved the weather forecasting over the last many years. The UK Met Office and the National Weather Service's climate data archive contains 45 petabytes of information. The researchers have used AI systems to rank spot cyclones, climate models, and extreme weather events using modeled and real-climate data. Machine Learning, slowly but surely, seems to be gaining ground for weather forecast and climate change study.

True AI doesn't exist's augmented intelligence 7wData


While many companies claim to provide "AI-driven" solutions, in reality they're leveraging machine learning techniques at best, developing what Ganzarski refers to as augmented intelligence. In an interview with Information Age, Ganzarski's discussed how he thinks this gap from augmented intelligence to Artificial Intelligence will be bridged, how long that will take and what the future of AI holds. Instead, tech companies claiming to do'AI' are actually providing what I would define as augmented intelligence – very sophisticated, fast decision processing or decision supporting software based on real-time scenarios. In the simplest of language, AI is a computer (software, robot, call it whatever you will) that has the ability to do things only a human can do, and use the same level of logic and reasoning that a human would.
