Online 1 on 1 class is created for more personalized learning experience. It demands a large number of teaching resources, which are scarce in China. To alleviate this problem, we build a platform (marketplace), i.e., \emph{Dahai} to allow college students from top Chinese universities to register as part-time instructors for the online 1 on 1 classes. To warn the unqualified instructors and ensure the overall education quality, we build a monitoring and alerting system by utilizing multimodal information from the online environment. Our system mainly consists of two key components: banned word detector and class quality predictor. The system performance is demonstrated both offline and online. By conducting experimental evaluation of real-world online courses, we are able to achieve 74.3\% alerting accuracy in our production environment.

Artificial intelligence (AI) and machine learning are amazing technologies that are revolutionizing practically every field of human activity. Intelligent machines can assist or downright substitute humans in literally all tasks, from business and commerce to health care, environment, communications, and any endeavors we can imagine. Understanding AI, while this tech is still in its prime days, is a great way to boost a career in technology. Professionals who can build thinking machines able to get the most value from the immense vaults of unstructured data currently floating around are highly sought after by employers across the globe. Whether you already have experience in the technology field or you are a student with little or no background in AI and programming, there are many online courses available to outpace your competition and find the job of your life.

The rush of intelligent machines and sophisticated analytics into many aspects of work means that trainees are losing opportunities to acquire skills through on-the-job learning (OJL). In medicine, policing, and other fields, people are finding rule-breaking ways to acquire needed expertise out of the limelight. This "shadow learning" is tolerated for the results it produces, but it can exact a personal and an organizational toll. In response, organizations should carefully uncover and study shadow learning; adapt practices that develop organizational, technological, and work designs that enhance OJL; and make intelligent machines part of the solution. It's 6:30 in the morning, and Kristen is wheeling her prostate patient into the OR. Today she's hoping to do some of the procedure's delicate, nerve-sparing dissection herself. The attending physician is by her side, and their four hands are mostly in the patient, with Kristen leading the way under his watchful guidance. The work goes smoothly, the attending backs away, and Kristen closes the patient by 8:15, with a junior resident looking over her shoulder.

These days you'll be hard-pressed to find someone who hasn't interrogated Siri (or Alexa), enjoyed the movie Netflix suggested, or fallen victim to purchasing that additional item Amazon recommended--all of which are only possible due to artificial intelligence. AI has been a field of study as far back as the 1950s, but advances have skyrocketed in recent years. These days AI is everywhere and has increasingly become part of all of our everyday lives. Thanks to AI, once tedious tasks are now simple, single-click activities. And as technology becomes even more pervasive, it will only continue to impact our personal and professional lives.

The first programming exercise "Twitter Sentiment Analysis in Python" is both fun and challenging, where you analyze tons of twitter message to find out the sentiments e.g.

What insights might be gleaned from an education platform that's entirely online? In a newly published paper on the preprint server Arxiv.org They say their method allowed for tracking changes in behavior among students over time, as well as trends in the broader educational system. "How students behave … is an important topic in educational data mining. Knowledge of this behavior in an educational system can help us understand how students learn and help guide the development for optimal learning based on actual use," wrote the coauthors.

Looking for Artificial Intelligence Tutorial to learn introduction to artificial intelligence? Grab the list of Best Artificial Intelligence Courses Online, Tutorials, and Training are offered by a number of massive open online course (MOOC) providers like Udemy, Coursera, and edX. Artificial Intelligence (AI) and machine intelligence are the most booming topics in every industry now. Some of these popular MOOC providers offer some in-depth artificial intelligence programs. The list of the Best Artificial Intelligence Certification is often taught by industry top AI researchers or experts and you will learn the best applications of artificial intelligence.

Like anything in life, the best way to learn about anything is to get your feet wet. Watch some TedTalks on YouTube, read some blog posts, find forums and groups on social media platforms, and read some books on the subject. But, ultimately, you must be realistic as to whether the subject actually interests you or not. Before you do decide to take the plunge, complete some free courses on the subject or if possible, paid ones and see if it really is for you. Another good piece of advice is to find someone who has done what you are intending to do. Pick their brains and find out how they did it, and whether they would recommend it or not.

Analysis of log data generated by online educational systems is an essential task to better the educational systems and increase our understanding of how students learn. In this study we investigate previously unseen data from Clio Online, the largest provider of digital learning content for primary schools in Denmark. We consider data for 14,810 students with 3 million sessions in the period 2015-2017. We analyze student activity in periods of one week. By using non-negative matrix factorization techniques, we obtain soft clusterings, revealing dependencies among time of day, subject, activity type, activity complexity (measured by Bloom's taxonomy), and performance. Furthermore, our method allows for tracking behavioral changes of individual students over time, as well as general behavioral changes in the educational system. Based on the results, we give suggestions for behavioral changes, in order to optimize the learning experience and improve performance.

Have you ever wondered whom to thank for some of the modern conveniences you might have started taking for granted, like Siri, Cortana or Alexa (assuming you agree these are conveniences)? The people at the Association for Computing Machinery (ACM) decided to thank Geoffrey Hinton, Yoshua Bengio and Yann LeCun in April of this year by honoring them with the Turing Award for their contributions to deep learning and neural networks. These contributions are put to use every time you log into your smartphone using fingerprint or facial recognition or when you use Google Photos or a voice assistant, and likely every time you use Amazon, Netflix, Facebook or Instagram. The advances in automatic language translation and autonomous cars in recent years arguably wouldn't have progressed as rapidly had it not been for the contributions of these three researchers. All of that is still an understatement of their contributions to artificial intelligence (AI).
