How someone might identify a dog. Important inputs that are given a lot of weight are highlighted in red. Notice how the neurons are organized into layers, where the further right the neurons are, the more abstract the input? In other words, the neurons on the left ask questions about general shapes and lines, whereas the neurons on the right ask questions about objects such as eyes or fur. Trained neural networks function in a very similar way, although they arrive at this conclusion after training with a lot of data.

As a input, we're given a simulator, a video-game. We use keyboard or joystick to drive around the circuit. The simulator records screen shots of the images and the decisions we made: steering angles, throttle and brake. The mission is to create a deep neural network to emulate the behavior of the human being, and the put this network to run the simulator autonomously. Look at my first attempt to do this project.

A Samsung Simband displays real-time results on conversational narrative and tone. In the past few years, wearables have offered to track many things, to predict illness, and even to give us rudimentary advice on staying healthy. The makers of a new device hope to expand the role that wearables can play in helping with day-to-day life, however, by adding'conversational wing-person' and'social coach' to their list of skills. Researchers from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) and Institute of Medical Engineering and Science (IMES) have developed programming to help those for whom conversation is difficult to navigate it with ease, and they've put it all in a wearable for real-time assistance. According to the team, the results of their study, "Predicting Latent Narrative Mood using Audio and Physiologic Data" [PDF], suggest that using such technology to pin down the tone of conversation as it happens is nearly within our reach--a potential boon for persons who experience anxiety, aspects of autism spectrum disorder, or other conditions that can make chewing the fat an intimidating prospect.

I also decided to add the following picture below, as it illustrates a method that was very popular 30 years ago but that seems to have been forgotten recently: mixture of Gaussian. In the example below, it is used to separate the data set into two clusters. Note that you can use a mixture of any distributions, not just Gaussian, for instance, (data-driven) estimated distributions such as those based on kernel density destination.

The University of Southern California has recently created the Center on Artificial Intelligence for Social Solutions or CAISS, specifically to develop uses of artificial intelligence--AI--for use cases of interest to social entrepreneurs. The Center is a collaboration between the USC Viterbi School of Engineering and the USC Suzanne Dworak-Peck School of Social Work. Eric Rice, an Associate Professor from the School of Social Work, has been tapped to lead CAISS. The potential for AI to be an effective tool for entrepreneurs with no background in technology is confirmed by Rice himself. When asked about his LinkedIn profile URL, he acknowledged not only that he doesn't have one, but also said, "I'm a bit of a Luddite."

The Cambridge Centre for Risk Studies in collaboration with the United Nations programme on Journalism and Public Information (UNICRI) present a workshop on the Risks and Benefits of Artificial Intelligence and Robotics. From sensing, finance, medicine, transportation and security, a technological revolution is taking place. Artificial Intelligence (AI) has been a feature of science fiction for almost a century, but it is only in more recent years that the prospect of autonomous robotics and artificially intelligent systems has really become viable. While this will potentially provide great opportunities, these developments are likely to have significant impacts upon the very functioning of society, posing practical, ethical, legal and security challenges – much of which is as of yet not fully appreciated or understood. The media and other sources of public information are central in ensuring that citizens and institutions have a realistic and balanced understanding of such technologies.

Today, Mark takes on that ongoing tension of artificial intelligence and jobs, looking at how things are looking for jobs in Government administration, healthcare, and education. Public sector jobs could be under threat by robots in the next 15 years, according to a new report by The Reform think-tank. As technology is advancing at an unprecedented rate, the report explains, there is a growing opportunity to improve efficiency to the tune of billions of pounds by engaging robots to undertake certain tasks. The tasks that these bots can undertake, however, may have ramifications for civil servants' jobs. The co-author of the report, Alexander Hitchcock, has put this caveat on The Reform's think-tank: "Such a rapid advance in the use of technology may seem controversial, and any job losses must be handled sensitively. But the result will be public services that are better, safer, smarter, and more affordable."

Jupyter notebook is a tool that helps you create readable ML code and results, as you can keep code, images, comments, formulae and plots together. It helps you keep the code, comments(in markdown) and results(as graphs/plots) together in a very presentable way. It also provides line by line code execution like scala/nodejs repls do. And autocompletion is thrown into the goodness mix as well. The presentability and ease of use of notebooks make them an ideal environment for learning a new language as well as Machine learning concepts.

Writing in the Economist newspaper on 8 October 2016, US President Barack Obama called out artificial intelligence (AI) as one of several areas where'in recent years we have seen incredible technological advances'.2 Long a backroom area of computer science, AI has captured the popular imagination over the last two years as the range and impact of practical AI applications have expanded at a dizzying pace: a quick search on ft.com for'artificial intelligence and robotics' returned 4 stories from September and October 2014, 16 for the same period in 2015 and 54 in 2016. AI is one of several areas of digital innovation that are all both developing increasingly rapidly and interacting with each other in ways whose consequences are challenging to foresee. A useful portmanteau for these changes is the'fourth industrial revolution'. After steam, electricity and computing, this is the term coined3 by Davos founder Klaus Schwab for the deep digital transformation now upon us.
