In my opinion, two innovations have reached clear "tipping points" in 2014 and herald the beginning of new times in the field of money and personal transportation. Software companies are taking leadership positions in established economies and will transform them in a durable manner. In less than a century, money will have gone from physical to plastic to digital. Driving will evolve from an art, mechanically operated by humans, to a science programmed by machine learning algorithms. Digital currency is pushing our economy squarely into the influence of the algorithm. In the case of driving, a new era is emerging – the era of machine learning. It's now become quite realistic that machines are able to execute functions at similar, if not higher, levels than humans. I'd like to propose we append Andreessen memo: "Software might eat the world, Marc, but, algorithms will end up digesting it." And since "money fuels our economy", I couldn't resist lumping both predictions in the same piece and proposing an appendix to Marc's memo.

UPDATE: Mar 20, 2016 - Added my new follow-up course on Deep Learning, which covers ways to speed up and improve vanilla backpropagation: momentum and Nesterov momentum, adaptive learning rate algorithms like AdaGrad and RMSProp, utilizing the GPU on AWS EC2, and stochastic batch gradient descent. We look at TensorFlow and Theano starting from the basics - variables, functions, expressions, and simple optimizations - from there, building a neural network seems simple! Deep learning is all the rage these days. What exactly is deep learning? Well, it all boils down to neural networks.

In this post you discovered artificial neural networks for machine learning. How neural networks are not models of the brain but are instead computational models for solving complex machine learning problems. That neural networks are comprised of neurons that have weights and activation functions. The networks are organized into layers of neurons and are trained using stochastic gradient descent. That it is a good idea to prepare your data before training a neural network model.

In recent years, we've seen a resurgence in AI, or artificial intelligence, and machine learning. Machine learning has led to some amazing results, like being able to analyze medical images and predict diseases on-par with human experts. Google's AlphaGo program was able to beat a world champion in the strategy game go using deep reinforcement learning. Machine learning is even being used to program self driving cars, which is going to change the automotive industry forever. Imagine a world with drastically reduced car accidents, simply by removing the element of human error.

About 20 percent of youth in the United States live with a mental health condition, according to the National Institute of Mental Health. The good news is that mental health professionals have smarter tools than ever before, with artificial intelligence-related technology coming to the forefront to help diagnose patients, often with much greater accuracy than humans. A new study published in the journal Suicide and Life-Threatening Behavior, for example, showed that machine learning is up to 93 percent accurate in identifying a suicidal person. The research, led by John Pestian, a professor at Cincinnati Children's Hospital Medical Center, involved 379 teenage patients from three area hospitals. Each patient completed standardized behavioral rating scales and participated in a semi-structured interview, answering five open-ended questions such as "Are you angry?" to stimulate conversation, according to a press release from the university.

Artificial intelligence and machine learning are predicted to be part of the next industrial revolution and could help business and industry save billions of dollars by the next decade. The tech giants Google, Facebook, Apple, IBM and others are applying artificial intelligence to all sorts of data. Machine learning methods are being used in areas such as translating language almost in real time, and even to identify images of cats on the internet. So why haven't we seen artificial intelligence used to the same extent in healthcare? Radiologists still rely on visual inspection of magnetic resonance imaging (MRI) or X-ray scans – although IBM and others are working on this issue – and doctors have no access to AI for guiding and supporting their diagnoses.

This was a week of tremendous loss. America said goodbye to John Glenn, the first American to orbit the Earth, Twitter accidentally murdered @-replies for a day, Fitbit cannibalized its new acquisition of Pebble and new studies suggest that robots are probably going to decimate retail jobs right after they finish working over those manufacturing and shipping positions. Numbers, because how else will you know how many survivors remain?

At KDnuggets, we try to keep our finger on the pulse of main events and developments in industry, academia, and technology. We also do our best to look forward to key trends on the horizon. We recently asked some of the leading experts in Big Data, Data Science, Artificial Intelligence, and Machine Learning for their opinion on the most important developments of 2016 and key trends they 2017. We generally asked participants to keep their responses to within 100 words or so, but were amenable to longer answers if the situation warranted. Without further delay, here is what we found.

No discussion of ML would be complete without at least mentioning neural networks. Not only do neural nets offer an extremely powerful tool to solve very tough problems, but they also offer fascinating hints at the workings of our own brains, and intriguing possibilities for one day creating truly intelligent machines. Neural networks are well suited to machine learning problems where the number of inputs is gigantic. The computational cost of handling such a problem is just too overwhelming for the types of systems we've discussed above. As it turns out, however, neural networks can be effectively tuned using techniques that are strikingly similar to gradient descent in principle. A thorough discussion of neural networks is beyond the scope of this tutorial, but I recommend checking out our previous post on the subject.

This is the 3rd part in my Data Science and Machine Learning series on Deep Learning in Python. At this point, you already know a lot about neural networks and deep learning, including not just the basics like backpropagation, but how to improve it using modern techniques like momentum and adaptive learning rates. You've already written deep neural networks in Theano and TensorFlow, and you know how to run code using the GPU. This course is all about how to use deep learning for computer vision using convolutional neural networks. These are the state of the art when it comes to image classification and they beat vanilla deep networks at tasks like MNIST.
