A.I. is everywhere at the moment, and it’s responsible for everything from the virtual assistants on our smartphones to the self-driving cars soon to be filling our roads to the cutting-edge image recognition systems reported on by yours truly. Unless you’ve been living under a rock for the past decade, there’s good a chance you’ve heard of it before — and probably even used it. Right now, artificial intelligence is to Silicon Valley what One Direction is to 13-year-old girls: an omnipresent source of obsession to throw all your cash at, while daydreaming about getting married whenever Harry Styles is finally ready to settle down. (Okay, so we’re still working on the analogy!) But what exactly is A.I.? — and can terms like “machine learning,” “artificial neural networks,” “artificial intelligence” and “Zayn Malik” (we’re still working on that analogy…) be used … [Read more...] about Machine learning? Neural networks? Here’s your guide to the many flavors of A.I.

September 10, 2018 - Written By Daniel Fuller A new simulator simply called Evolution, which is available in a desktop browser and on the Play Store, uses a neural network to bring to life any creatures you can think to cobble together from an assortment of joints, bones and muscles that you can place wherever and link however you see fit. The creatures all spawn and learn across multiple generations, with two specimens chosen per generation to pass on their genes. No two simulations will ever be the same thanks to the wiles of the random mating, The created species will try their hands at three tasks to determine their fitness score; walking, jumping, and climbing stairs.The simulation is actually pretty simple on the surface, despite the complex neural networking and artificial intelligence operations happening just beneath. All you have to do is tap or click where you want to place joints, connect those using bones, then link the bones with muscles. Muscles can expand and … [Read more...] about Evolution Simulator Is Driven By A Neural Network
What is deep learning?Deep learning is a subset of machine learning, which itself falls within the field of artificial intelligence.What is the difference between deep learning, machine learning and AI?Artificial intelligence is the study of how to build machines capable of carrying out tasks that would typically require human intelligence.That rather loose definition means that AI encompasses many fields of research, from genetic algorithms to expert systems, and provides scope for arguments over what constitutes AI.Within the field of AI research, machine learning has enjoyed remarkable success in recent years -- allowing computers to surpass or come close to matching human performance in areas ranging from facial recognition to speech and language recognition.Machine learning is the process of teaching a computer to carry out a task, rather than programming it how to carry that task out step by step. At the end of training, a machine-learning system will be able to make … [Read more...] about What is deep learning? Everything you need to know
Neural networks have a reputation for being computationally expensive. But only the training portion of things really stresses most computer hardware, since it involves regular evaluations of performance and constant trips back and forth to memory to tweak the connections among its artificial neurons. Using a trained neural network, in contrast, is a much simpler process, one that isn't nearly as computationally complex. In fact, the training and execution stages can be performed on completely different hardware. And there seems to be a fair bit of flexibility in the hardware that can be used for either of these two processes. For example, it's possible to train neural networks using a specialized form of memory called a memristor or execute trained neural networks using custom silicon chips. Now, researchers at UCLA have done something a bit more radical. After training a neural network using traditional computing hardware, they 3D printed a set of panels that manipulated light in a … [Read more...] about Neural network implemented with light instead of electrons
IBM today announced the launch of its Adversarial Robustness Toolbox for AI developers. The open-source kit contains everything a machine learning programmer needs to attack their own deep learning neural networks (DNN) to ensure they’re able to withstand real-world conditions. The toolbox comes in the form of a code library which includes attack agents, defense utilities, and benchmarking tools that allow developers to integrate baked-in resilience to adversarial attacks. The company says it’s the first of its kind. According to IBM Security Systems CTO Sridhar Muppidi: One of the biggest challenges with some of the existing models to defend against adversarial AI is they are very platform specific. The IBM team designed their Adversarial Robustness Toolbox to be platform agnostic. Whether you’re coding/developing in Keras or TensorFlow, you can apply the same library to build defenses in. It’s like a mixed martial arts trainer for AI that assesses a … [Read more...] about IBM’s new AI toolbox puts your deep learning network to the test
