CTR prediction in real-world business is a difficult machine learning problem with large scale nonlinear sparse data. In this paper, we introduce an industrial strength solution with model named Large Scale Piece-wise Linear Model (LS-PLM). We formulate the learning problem with $L_1$ and $L_{2,1}$ regularizers, leading to a non-convex and non-smooth optimization problem. Then, we propose a novel algorithm to solve it efficiently, based on directional derivatives and quasi-Newton method. In addition, we design a distributed system which can run on hundreds of machines parallel and provides us with the industrial scalability. LS-PLM model can capture nonlinear patterns from massive sparse data, saving us from heavy feature engineering jobs. Since 2012, LS-PLM has become the main CTR prediction model in Alibaba's online display advertising system, serving hundreds of millions users every day.

Machine Learning, Edge Computing and Serverless are the three key technologies that will redefine the Cloud Computing platforms. Machine Learning (ML) is becoming an integral part of modern applications. From the web to mobile to IoT, ML is powering the new breed of applications through natural user experiences and inbuilt intelligence. After virtualization and containerization, Serverless is emerging as the next wave of compute services. Serverless or Functions as a Service (FaaS) attempts to simplify the developer experience by minimizing the operational overhead in deploying and managing code.

Google has a number of research projects underway aimed at making computers smarter and technically versatile. One of those projects involves teaching machines how to draw. On April 11, Google researchers released a technical paper describing "sketch-rnn", a neural network that has been trained by using thousands of crude human-drawn images to construct basic drawings of its own. One of the goals of the paper is to show that machines can be taught to draw certain things, like the sketch of a house, a tree or a dog, in a manner similar to humans. "As humans, we do not understand the world as a grid of pixels, but rather develop abstract concepts to represent what we see," wrote two of the papers authors, David Ha and Douglas Eck, who are researchers with Google Brain, the company's deep learning research group.

In our world, many of the commonly encountered problems are classification problems. We are often confused between definite values or rigid choices of things. In this article, we will discuss about an algorithm used to solve simple classification problems effectively using Machine Learning. Also, we will analyze a hypothetical Binary Class problem involving Grad-School outcomes based on the Entrance Exam Marks and the Undergrad Marks. Supervised Learning is a machine learning technique in which we associate our inputs with our targets in the given dataset. We already have a definite intuition regarding our final output.

Let's take a breath: Robots and artificial intelligence systems are nowhere near displacing the human workforce. Nevertheless, no less a voice than Bill Gates has asserted just the opposite and called for a counterintuitive, preemptive strike on these innovations. His proposed weapon of choice? Taxes on technology to compensate for losses that haven't happened. David Kenny (@davidwkenny) is IBM's senior vice president for Watson and the company's cloud platform.

This is Deep Learning, Machine Learning, and Data Science Prerequisites: The Numpy Stack in Python. One question or concern I get a lot is that people want to learn deep learning and data science, so they take these courses, but they get left behind because they don't know enough about the Numpy stack in order to turn those concepts into code. Even if I write the code in full, if you don't know Numpy, then it's still very hard to read. This course is designed to remove that obstacle - to show you how to do things in the Numpy stack that are frequently needed in deep learning and data science. This forms the basis for everything else.

Data science and machine learning have long been interests of mine, but now that I'm working on Fuzzy.ai and trying to make AI and machine learning accessible to all developers, I need to keep on top of all the news in both fields. My preferred way to do this is through listening to podcasts. I've listened to a bunch of machine learning and data science podcasts in the last few months, so I thought I'd share my favorites: Every other week, they release a 10–15 minute episode where hosts, Kyle and Linda Polich give a short primer on topics like k-means clustering, natural language processing and decision tree learning, often using analogies related to their pet parrot, Yoshi. This is the only place where you'll learn about k-means clustering via placement of parrot droppings. Hosted by Katie Malone and Ben Jaffe of online education startup Udacity, this weekly podcast covers diverse topics in data science and machine learning: teaching specific concepts like Hidden Markov Models and how they apply to real-world problems and datasets.

Machine Learning means a machine which is learning on itself and is a method of automated data analysis. It is the science that enables computers to analyze data and automatically build models from that data. The machine can feed on data and adapt itself to make more precise predictions and act accordingly. Machine Learning has been there all the time. Do you remember simple pattern recognition algorithms?

With the number of commercial drones expected to soar into the millions in the next few years, operators whose unmanned aircraft malfunction or crash will be looking for places to get them fixed. Some repair shops authorized by manufacturers to fix smaller drones are already having trouble keeping up with demand. For several weeks, a California company had a note posted on its website referring specifically to the Phantom drone: "Temporarily not accepting any new repairs at this time due to high volume. The message was recently removed. While such waits might be frustrating for operators, it spells opportunity for repair shops keen to diversify and budding drone mechanics who could start lucrative careers repairing commercial drones without having to pay for a four-year college degree. "I'm trying to hire two experienced drone technicians at $20 an hour and I can't find anybody," said James Barnes, who founded the New Jersey Drone Academy. "This gives kids in urban areas that can't go to college now a chance to work at a trade and make decent money." Northland Community and Technical College in Minnesota has been teaching unmanned aircraft maintenance for larger military-type drones. It is expanding its program to include smaller drone repair, and school officials are promising a high-paying job after just one or two years. "The reality is, the people coming out of the trade schools, the technical colleges, places like that, are the people out there getting jobs and they're getting paid nicely to do it," said Zack Nicklin, unmanned aircraft instructor at the school in Thief River Falls, Minn. Unmanned aircraft owners basically have three options when their drones need tune-ups or repairs. They can send it back to the manufacturer, send it to a repair shop or fix it themselves. Most smaller shops specialize in hobby grade or low-end commercial grade drones, specific to a few manufacturers. Those drones typically cost a few thousand dollars to buy, and about $150 to fix, not including parts. The more expensive commercial drones generally need repair experts, many of whom have backgrounds in manned aviation. Brad Hayden of Albuquerque, N.M., is president and CEO of Robotic Skies, which is building a network of affiliated repair stations around the world. He currently has more than 120 service stations, most of which work on higher-end drones that cost $10,000 and up, and he plans to recruit more shops, as needed. "The industry is always short of avionics technicians.

The meaning of "work" is changing, and with life expectancies growing, the gig economy taking hold and artificial intelligence taking plenty of people's jobs, millennials will have careers that are worlds away from those of their forebears, says Dr. Linda Sharkey, global managing director of the consulting firm Achieveblue Inc. Sharkey is the author of "The Future-Proof Workplace: Six Strategies to Accelerate Talent Development, Reshape Your Culture and Succeed with Purpose," co-written with Morag Barnett, the chief executive of the business management consultancy SkyeTeam. She talked to International Business Times about the prospects for 21st-century careers, the falling value of a four-year degree and the idea that a robot might be conducting this sort of question-and-answer article in the not-so-far-away future. This interview has been edited and condensed for clarity. One issue you touch on in your book is your expectation that retirement will cease to be a 21st century phenomenon, and that today's young workers are more likely to take sabbaticals than end their careers by their late sixties. Is this something you think will be born of choice -- a desire to work longer -- or a consequence of the unsustainability of Social Security as generations live longer and have fewer children?
