Machine learning enhances non-verbal communication in online classrooms


June 21, 2021--Researchers in the Center for Research on Entertainment and Learning (CREL) at the University of California San Diego have developed a system to analyze and track eye movements to enhance teaching in tomorrow's virtual classrooms – and perhaps future virtual concert halls. UC San Diego music and computer science professor Shlomo Dubnov, an expert in computer music who directs the Qualcomm Institute-based CREL, began developing the new tool to deal with a downside of teaching music over Zoom during the COVID-19 pandemic. "In a music classroom, non-verbal communication such as facial affect and body gestures is critical to keep students on task, coordinate musical flow and communicate improvisational ideas," said Dubnov. "Unfortunately, this non-verbal aspect of teaching and learning is dramatically hampered in the virtual classroom where you don't inhabit the same physical space." To overcome the problem, Dubnov and Ph.D. student Ross Greer recently published a conference paper on a system that uses eye tracking and machine learning to allow an educator to make'eye contact' with individual students or performers in disparate locations – and lets each student know when he or she is the focus of the teacher's attention.

Learn to code, build your own app or video game, and more with these $20 course bundles


A certain world-dominating website might be having its biggest sale of the year, but it's far from the only place you can score major deals. In fact, you can't even find deals on things like online courses on the retail giant's site -- but you can below. For a limited time, these 12 course bundles are on sale for as little as $1.11 per course. Why not spend your money on bettering yourself this season? Experts consider Python to be one of the best programming languages for beginners, thanks to its straightforward syntax and minimal setup.

Online Learning with LakeFS and AWS


Most tutorials/articles are usually focused on paper reviews and the performance of machine learning models in a lab. However, a significantly overlooked area is putting models into production and monitoring their performance, called online machine learning or online learning, where the model constantly learns from new data. The main advantage of online learning is that it prevents data from going "stale". Sometimes, the nature and distribution of the data are likely to change over time. If your model doesn't keep on improving, its performance will keep on decreasing.

Data Science: Machine Learning


Perhaps the most popular data science methodologies come from machine learning. What distinguishes machine learning from other computer guided decision processes is that it builds prediction algorithms using data. Some of the most popular products that use machine learning include the handwriting readers implemented by the postal service, speech recognition, movie recommendation systems, and spam detectors. In this course, part of our Professional Certificate Program in Data Science, you will learn popular machine learning algorithms, principal component analysis, and regularization by building a movie recommendation system. You will learn about training data, and how to use a set of data to discover potentially predictive relationships.

Applied Machine Learning in Python


This course will introduce the learner to applied machine learning, focusing more on the techniques and methods than on the statistics behind these methods. The course will start with a discussion of how machine learning is different than descriptive statistics, and introduce the scikit learn toolkit through a tutorial. The issue of dimensionality of data will be discussed, and the task of clustering data, as well as evaluating those clusters, will be tackled. Supervised approaches for creating predictive models will be described, and learners will be able to apply the scikit learn predictive modelling methods while understanding process issues related to data generalizability (e.g. The course will end with a look at more advanced techniques, such as building ensembles, and practical limitations of predictive models.

AI Guide for Businesses Created by CompTIA Artificial Intelligence Advisory Council


As more companies explore the viability of adding artificial intelligence into their business processes, a new resource from CompTIA, the nonprofit association for the information technology (IT) industry and workforce, offers guidance, answers questions and provides information to help in the decision-making process. "Artificial Intelligence in Business: Top Considerations Before Implementing AI" was produced by the CompTIA Artificial Intelligence Advisory Council, a group of thought leaders and innovators committed to accelerating the adoption of AI and machine learning technologies. "AI is already prevalent in many business processes and applications used daily, and there are almost limitless other opportunities where it can be utilized," said Annette Taber, senior vice president for industry outreach and relations at CompTIA. "However, AI processes are complex. The key to a successful deployment is asking the right questions and understanding what's involved before making any investments."

Microsoft is Putting AI to Work for a Sustainable Planet


Microsoft is using its machine learning technology Azure to fight climate changes, pollution, and other environmental complexities. Azure is providing AI-based computing solutions to work on environmental sustainability projects. Our planet is currently facing a climate crisis and several large tech companies have come forward to assist scientists and researchers to improve the deteriorating situation. Microsoft has enabled its AI and machine learning technologies to fight against such anomalies and drive our planet towards a sustainable future. The company has developed two APIs especially made for Earth and continues to work on more such technologies and initiatives.

Andrew Ng Launches A Campaign For Data-Centric AI


Data is eating the world so Andrew Ng wants to make sure we radically improve its quality. "Data is food for AI," says Ng, and he is launching a campaign to shift the focus of AI practitioners from model/algorithm development to the quality of the data they use to train the models. Landing AI, the startup Ng founded to bring AI to traditional industries, today announced a competition to get the best performance out of a fixed model by improving the quality of the data. The top three winners will be invited to a private roundtable event with Andrew Ng to share ideas and explore how to grow the data-centric movement. In addition, DeepLearning.AI, an education startup Ng also founded, is launching an online course to teach his data-centric approach to a worldwide audience on Coursera (which Ng co-founded in 2012).
