Google teaches robots to learn from each other

#artificialintelligence

The robots of the world are uniting โ€“ and that's either a great thing or a terrifying thing depending on your view. Google has a plan to speed up robotic learning, and it involves getting robots to share their experiences โ€“ via the cloud โ€“ and collectively improve their capabilities โ€“ via deep learning. Sergey Levine from the Google Brain team, along with collaborators from Alphabet subsidiaries DeepMind and GoogleX, published a blog post on Monday describing an approach for "general-purpose skill learning across multiple robots." Teaching robots how to do even the most basic tasks in real world settings such as homes and offices has vexed roboticists for decades. To tackle this challenge, the Google researchers decided to combine two recent technology advances.


AI collaboration will let robots think for themselves - Drives and Controls Magazine

The Japanese robot-maker Fanuc has teamed up with the computer technology specialist Nvidia to apply artificial intelligence (AI) to robotics to boost productivity and to bring new capabilities to automated factories. The partners will use AI to give robots the ability to teach themselves to perform tasks faster and more efficiently, and to work together, so that a task that would previously have taken one robot eight hours to complete, could now be done by eight robots in an hour. The robots will be able to learn on their own, instead of being programmed painstakingly--for each function they need to perform. The technology is based on --deep learning"--software, accelerated using Nvidia GPUs (graphics processing units), which will support AI in the cloud, in data centres and embedded in devices. The AI will be implemented on Fanuc--s Field (Fanuc Intelligent Edge Link and Drive) platform, which combines AI with edge computing to process --edge-heavy-- sensor data from machines to allow them to collaborate intelligently and flexibly.

Neural networking with advanced parallel processing is beginning to take root in a number of markets ranging from predicting earthquakes and hurricanes to parsing MRI image datasets in order to identify and classify tumors. As this approach gets implemented in more places, it is being customized and parsed in ways that many experts never envisioned. And it is driving new research into how else these kinds of compute architectures can be applied. Fjodor van Veen, deep learning researcher at The Asimov Institute in the Netherlands, has identified 27 distinct neural net architecture types. The differences are largely application-specific. Neural networking is based on the concept of threshold logic algorithms, which were first proposed in 1943 by Warren McCulloch, a neurophysiologist, and Walter Pitts, a logician.

Here we propose a reimplementation of their method and discuss future applications of the technology. Convolutional neural networks (CNN) are now standard neural network layers for computer vision. Transposed convolutions (sometimes referred to as deconvolution) are the GRADIENTS of a convolutional layer. Transposed convolutions were, as far as we know first used by Zeiler and Fergus [2] for visualization purposes while improving their AlexNet model. For visualization purposes let us check out that convolutions in the present subject are a sequence of inner product of a given filter (or kernel) with pieces of a larger image.


Unlocking the power of AI for all developers

#artificialintelligence

The use of artificial intelligence (AI) in the form of artificial neural networks -- in particular, deep neural networks (DNNs) -- is poised to experience exponential growth in a wide variety of embedded systems, but who is going to define, create, and train these little scamps? Before we plunge into the fray with gusto and abandon, it's worth noting that many people think of DNNs only in the context of computer/machine/embedded vision applications. In reality, however, these little rascals are applicable to a wide variety of tasks (see Deep learning hits a sweet note). There are several steps involved in creating a DNN. The first is to define and implement the network architecture and topology.



Revisiting Multiple Instance Neural Networks

arXiv.org Machine Learning

Recently neural networks and multiple instance learning are both attractive topics in Artificial Intelligence related research fields. Deep neural networks have achieved great success in supervised learning problems, and multiple instance learning as a typical weakly-supervised learning method is effective for many applications in computer vision, biometrics, nature language processing, etc. In this paper, we revisit the problem of solving multiple instance learning problems using neural networks. Neural networks are appealing for solving multiple instance learning problem. The multiple instance neural networks perform multiple instance learning in an end-to-end way, which take a bag with various number of instances as input and directly output bag label. All of the parameters in a multiple instance network are able to be optimized via back-propagation. We propose a new multiple instance neural network to learn bag representations, which is different from the existing multiple instance neural networks that focus on estimating instance label. In addition, recent tricks developed in deep learning have been studied in multiple instance networks, we find deep supervision is effective for boosting bag classification accuracy. In the experiments, the proposed multiple instance networks achieve state-of-the-art or competitive performance on several MIL benchmarks. Moreover, it is extremely fast for both testing and training, e.g., it takes only 0.0003 second to predict a bag and a few seconds to train on a MIL datasets on a moderate CPU.


Attribute2Image: Conditional Image Generation from Visual Attributes

arXiv.org Artificial Intelligence

This paper investigates a novel problem of generating images from visual attributes. We model the image as a composite of foreground and background and develop a layered generative model with disentangled latent variables that can be learned end-to-end using a variational auto-encoder. We experiment with natural images of faces and birds and demonstrate that the proposed models are capable of generating realistic and diverse samples with disentangled latent representations. We use a general energy minimization algorithm for posterior inference of latent variables given novel images. Therefore, the learned generative models show excellent quantitative and visual results in the tasks of attribute-conditioned image reconstruction and completion.


Demystifying Artificial Intelligence buzzwords

#artificialintelligence

Much research in this field has led to new advances and improvements in this space, leading to the new research in the areas of machine intelligence, machine learning and deep learning. But what do these words and terms mean? How are they related to each other? This is the overarching term which encompasses all of these research areas. It is usually defined as the science of making computers complete tasks which usually require human intelligence, like learning, decision making and problem solving.


Why This Skeptic Believes in Artificial Intelligence

#artificialintelligence

"Unicorn," for example, a rare private company valued at more than 1 billion, is a description that outwore its welcome once there were so many of them. In other words, I need convincing that the latest hot topic in Silicon Valley is worth the effort to understand. Reading Roger Parloff's insightful feature in the current issue of Fortune, "Why Deep Learning Is Suddenly Changing Your Life," I became convinced about the catch-all phrase artificial intelligence and its subset fields of study, including machine learning and deep learning, also knowns as deep neural nets. There isn't space here to do justice to this complex topic. But one quote from Parloff's masterful story might convince you to take the time to go deeper.
