There didn't seem to be anything strange about the new teaching assistant, Jill Watson, who messaged students about assignments and due dates in professor Ashok Goel's artificial intelligence class at the Georgia Institute of Technology. Her responses were brief but informative, and it wasn't until the semester ended that the students learned Jill wasn't actually a "she" at all, let alone a human being. Jill was a chatbot, built by Goel to help lighten the load on his eight other human TAs. "We thought that if an AI TA would automatically answer routine questions that typically have crisp answers, then the (human) teaching staff could engage the students on the more open-ended questions," Goel told Digital Trends. "It is only later that we became motivated by the goal of building human-like AI TAs so that the students cannot easily tell the difference between human and AI TAs. Now we are interested in building AI TAs that enhance student engagement, retention, performance, and learning."

As more companies begin to experiment with and deploy machine learning in different settings, it's good to look ahead at what future systems might look like. Today, the typical sequence is to gather data, learn some underlying structure, and deploy an algorithm that systematically captures what you've learned. Gathering, preparing, and enriching the right data--particularly training data--is essential and remains a key bottleneck among companies wanting to use machine learning. I take for granted that future AI systems will rely on continuous learning as opposed to algorithms that are trained offline. Humans learn this way, and AI systems will increasingly have the capacity to do the same.

Hi! I'm Jose Portilla and I'm an instructor on Udemy with over 250,000 students enrolled across various courses on Python for Data Science and Machine Learning, R Programming for Data Science, Python for Big Data, and many more. What should I do to become a data scientist? In this post, I'll try my best to help answer this question and point to resources that can help guide you to an answer, also hopefully this post serves as something I can quickly link to my students:) I've broken down the steps into some key topics and discussed helpful details for each. "The secret of getting ahead is getting started." If you are interested in becoming a data scientist the best advice is to begin preparing for your journey now!

When I was studying political science in college, I had no intention of going into the field of technology. I had friends in STEM, but I was sure I either wanted to pursue a career in politics or business. However, when I saw an opportunity to enter a rotational program at IBM Watson starting in the summer of 2014, I knew I had to pursue it. I got the job and rotated through the sales and marketing departments, where I began learning more about AI technology. As I talked to developers both inside and outside of the company, I found myself wanting to learn how to code with the Watson API's and create a new product or app.

Two Los Angeles Unified teachers play a tabletop game created during a two-day professional development workshop last week at the Annenberg Space for Photography's Skylight Studios. About 1,000 middle and high school students in Los Angeles are expected to design video games this school year that expose players to the importance of kindness, wildlife conservation or news literacy. The best student gamemakers could earn scholarships and other prizes. With the gaming effort, it recruited Riot Games, the Los Angeles company behind the hit computer game "League of Legends," to host participants on upcoming field trips.

Over the years, Andrew Ng has worn many hats -- Coursera co-founder, former Baidu chief scientist, founding lead of Google Brain team, and Stanford University adjunct professor. But lately, he has emerged as the leading influencer championing artificial intelligence (AI). Well over 1.5 million people have enrolled in his AI courses in Coursera. In a chat with ET, Ng talks about recent AI controversies: Elon Musk Versus Mark Zuckerberg spat on dangers of AI, Facebook AI chatbots creating their own language and job displacements. Edited excerpts: In an experiment recently, Facebook chatbots created their own language and had to be shut down.

Scientists who build artificial intelligence and autonomous systems need a strong ethical understanding of the impact their work could have. More than 100 technology pioneers recently published an open letter to the United Nations on the topic of lethal autonomous weapons, or "killer robots". These people, including the entrepreneur Elon Musk and the founders of several robotics companies, are part of an effort that began in 2015. The original letter called for an end to an arms race that it claimed could be the "third revolution in warfare, after gunpowder and nuclear arms". The UN has a role to play, but responsibility for the future of these systems also needs to begin in the lab. The education system that trains our AI researchers needs to school them in ethics as well as coding.

In many real-world machine learning problems the same data is comprised of several different representations or views. For example, same documents may be available in multiple languages [1] or different descriptors can be constructed from the same images [2]. Although each of these individual views may be sufficient to perform a learning task, integrating complementary information from different views can reduce the complexity of a given task [3]. Multi-view clustering seeks to partition data points based on multiple representations by assuming that the same cluster structure is shared across views. By combining information from different views, multi-view clustering algorithms attempt to achieve more accurate cluster assignments than one can get by simply concatenating features from different views. In practice, high-dimensional data often reside in a low-dimensional subspace. When all data points lie in a single subspace, the problem can be set as finding a basis of a subspace and a low-dimensional representation of data points. Depending on the constraints imposed on the lowdimensional representation, this problem can be solved using e.g.

Large-scale deep neural networks (DNNs) are both compute and memory intensive. As the size of DNNs continues to grow, it is critical to improve the energy efficiency and performance while maintaining accuracy. For DNNs, the model size is an important factor affecting performance, scalability and energy efficiency. Weight pruning achieves good compression ratios but suffers from three drawbacks: 1) the irregular network structure after pruning; 2) the increased training complexity; and 3) the lack of rigorous guarantee of compression ratio and inference accuracy. To overcome these limitations, this paper proposes CirCNN, a principled approach to represent weights and process neural networks using block-circulant matrices. CirCNN utilizes the Fast Fourier Transform (FFT)-based fast multiplication, simultaneously reducing the computational complexity (both in inference and training) from O(n2) to O(nlogn) and the storage complexity from O(n2) to O(n), with negligible accuracy loss. Compared to other approaches, CirCNN is distinct due to its mathematical rigor: it can converge to the same effectiveness as DNNs without compression. The CirCNN architecture, a universal DNN inference engine that can be implemented on various hardware/software platforms with configurable network architecture. To demonstrate the performance and energy efficiency, we test CirCNN in FPGA, ASIC and embedded processors. Our results show that CirCNN architecture achieves very high energy efficiency and performance with a small hardware footprint. Based on the FPGA implementation and ASIC synthesis results, CirCNN achieves 6-102X energy efficiency improvements compared with the best state-of-the-art results.
