Google DeepMind AI teaches itself using snippets of video
Google's DeepMind has developed an AI that identifies pictures and sounds in snippets of video before being told by a human what it is watching. The incredible system uses an algorithm to recognise things such as crowds, people dancing and water, without seeing a specific label for any of them. Currently most algorithms need to be told what images are to tell them apart - for example they need to be told something is a dog before understanding it as such. This research takes AI closer to being able to teach itself by watching the world around it - just like humans do everyday. This advanced algorithm was created by combing one network that was expert at recognising images and another that could identify audio.
How Convolutional Neural Networks Accomplish Image Recognition?
What is Image Recognition and why is it Used? In the context of machine vision, image recognition is the capability of a software to identify people, places, objects, actions and writing in images. To achieve image recognition, the computers can utilise machine vision technologies in combination with artificial intelligence software and a camera. While it is very easy for human and animal brains to recognize objects, the computers have difficulty with the same task. When we look at something like a tree or a car or our friend, we usually don't have to study it consciously before we can tell what it is.
Google's Tensor2Tensor makes it easier to conduct deep learning experiments
Google's brain team is open sourcing Tensor2Tensor, a new deep learning library designed to help researchers replicate results from recent papers in the field and push the boundaries of what's possible by trying new combinations of models, datasets and other parameters. The sheer number of variables in AI research combined with the fast pace of new developments makes it difficult for experiments run in two distinct settings to match. This is a pain for researchers and a drag on research progress. The Tensor2Tensor library makes it easier to maintain best practices while conducting AI research. It comes equipped with key ingredients including hyperparameters, data-sets, model architectures and learning rate decay schemes.
Six years later, Coursera's Andrew Ng returns with new Deep Learning courses
The Deep Learning Specialization consists of five different courses. The courses are free to take, but you need to sign up for a subscription of $49/month if you want access to the graded assignments or earn certificates. There is a seven day free trial. The individual courses are free, but you need to visit the course pages separately (you can't sign up to them from the Specialization page). Though the courses officially start on 15 August, the course materials for the first three courses are already available.
What is machine learning? Software derived from data
You've probably encountered the term "machine learning" more than a few times lately. Often used interchangeably with artificial intelligence, machine learning is in fact a subset of AI, both of which can trace their roots to MIT in the late 1950s. Machine learning is something you probably encounter every day, whether you know it or not. The Siri and Alexa voice assistants, Facebook's and Microsoft's facial recognition, Amazon and Netflix recommendations, the technology that keeps self-driving cars from crashing into things โ all are a result of advances in machine learning. While still nowhere near as complex as a human brain, systems based on machine learning have achieved some impressive feats, like defeating human challengers at chess, Jeopardy, Go, and Texas Hold'em.
D.I.Y. Artificial Intelligence Comes to a Japanese Family Farm
Not much about Makoto Koike's adult life suggests that he would be a farmer. Trained as an engineer, he spent most of his career in a busy urban section of Aichi Prefecture, Japan, near the headquarters of the Toyota Motor Corporation, writing software to control cars. Koike's longtime hobby is tinkering with electronic kits and machines; he is not naturally an outdoorsy type. Yet, in 2014, at the age of thirty-three, he left his job and city life to move to his parents' cucumber farm, in the greener prefecture of Shizuoka. "I thought I was getting old," Koike told me.
Google DeepMind AI Declares Galactic War on StarCraft
Tic-tac-toe, checkers, chess, Go, poker. Artificial intelligence rolled over each of these games like a relentless tide. No one expects the robot to win anytime soon. But when it does, it will be a far greater achievement than DeepMind's conquest of Go--and not just because StarCraft is a professional e-sport watched by fans for millions of hours each month. DeepMind and Blizzard Entertainment, the company behind StarCraft, just released the tools to let AI researchers create bots capable of competing in a galactic war against humans.
McKinsey Analytics: What can deep learning do for your business?
Organizations have been sitting on mountains of valuable data with no efficient way to unlock its potential. A powerful type of machine learning, called deep learning, can now unleash the power of data to drive competitive advantage.

Time Series Analysis With Generalized Additive Models
These correlations between past and present values demonstrate temporal dependence, which forms the basis of a popular time series analysis technique called ARIMA (Autoregressive Integrated Moving Average). Long short-term memory (LSTM) networks are a type of neural networks that builds models based on temporal dependence. Therefore, google search trends for persimmons could well be modeled by adding a seasonal trend to an increasing growth trend, in what's called a generalized additive model (GAM). The principle behind GAMs is similar to that of regression, except that instead of summing effects of individual predictors, GAMs are a sum of smooth functions.
Get the Most out of LSTMs on Your Sequence Prediction Problem - Machine Learning Mastery
Long Short-Term Memory (LSTM) Recurrent Neural Networks are a powerful type of deep learning suited for sequence prediction problems. A possible concern when using LSTMs is if the added complexity of the model is improving the skill of your model or is in fact resulting in lower skill than simpler models. In this post, you will discover simple experiments you can run to ensure you are getting the most out of LSTMs on your sequence prediction problem.

The LSTM recurrent neural network has a few key capabilities that give the method its impressive power on a wide range of sequence prediction problems.
