Google's DeepMind now learning by challenging Atari
In order to train DeepMind the company elected to show the artificial intelligence platform YouTube videos of games being played, rather than go through the painstaking process of playing against the platform game after game. The aim was to try to strengthen a weakness with artificial intelligence: one of exploration. Most platforms are weak in attempting to find new places to go, and this is a step towards thinking creatively. The gaming platform used to help improve artificial intelligence was classic Atari video games. The main game used was Montezuma's Revenge, which is a 1984 platform game for Atari 8-bit computers.
Demystifying Deep Learning - Back to Basics Vinod Sharma's Blog
This is part 1 of 2 parts story on DeepLearning & basic terms which revolve (may evolve around as well) around it. Deep Learning is a very young field, where theories aren't strongly established and views quickly changes almost on daily basis. Deep Learning is at the cutting edge technology break through. This depicts what machines can do (still very new and at basic level), and developers and business leaders absolutely need to understand what it is and how it works. "I think people needs to understand that deep learning is making a lot of things, behind the scenes, much better" โ Sir Geoffrey Hinton With lots of noise I can say "Deep learning is undeniably mind-blowing" and "deep learning can be used with too much of ease to predict the unpredictable".
Opinion No good reason to create artificial intelligence 'psychopath'
Scientists Pinar Yanardag, Manuel Cebrian and Iyad Rahwan specifically trained Norman to perform image captioning, a "deep learning method" for artificial intelligence to collate images and then spew out corresponding text descriptions. To wit: A standard AI, unpolluted by Reddit, sees in an inkblot "a person holding an umbrella in the air." Norman saw: "Man is electrocuted while attempting to cross busy street." Norman saw: "Man gets pulled into dough machine." Norman saw: "Man killed by speeding driver."
An Augmented Reality Microscope for Cancer Detection - ADR Toolbox
Applications of deep learning to medical disciplines including ophthalmology, dermatology, radiology, and pathology have recently shown great promise to increase both the accuracy and availability of high-quality healthcare to patients around the world. At Google, we have also published results showing that a convolutional neural network is able to detect breast cancer metastases in lymph nodes at a level of accuracy comparable to a trained pathologist. However, because direct tissue visualization using a compound light microscope remains the predominant means by which a pathologist diagnoses illness, a critical barrier to the widespread adoption of deep learning in pathology is the dependence on having a digital representation of the microscopic tissue. Today, in a talk delivered at the Annual Meeting of the American Association for Cancer Research (AACR), with an accompanying paper "An Augmented Reality Microscope for Real-time Automated Detection of Cancer" (under review), we describe a prototype Augmented Reality Microscope (ARM) platform that we believe can possibly help accelerate and democratize the adoption of deep learning tools for pathologists around the world. The platform consists of a modified light microscope that enables real-time image analysis and presentation of the results of machine learning algorithms directly into the field of view.
Intuitively Understanding Convolutions for Deep Learning
The advent of powerful and versatile deep learning frameworks in recent years has made it possible to implement convolution layers into a deep learning model an extremely simple task, often achievable in a single line of code. However, understanding convolutions, especially for the first time can often feel a bit unnerving, with terms like kernels, filters, channels and so on all stacked onto each other. Yet, convolutions as a concept are fascinatingly powerful and highly extensible, and in this post, we'll break down the mechanics of the convolution operation, step-by-step, relate it to the standard fully connected network, and explore just how they build up a strong visual hierarchy, making them powerful feature extractors for images. The 2D convolution is a fairly simple operation at heart: you start with a kernel, which is simply a small matrix of weights. This kernel "slides" over the 2D input data, performing an elementwise multiplication with the part of the input it is currently on, and then summing up the results into a single output pixel.
GDPR is an opportunity for AI companies to build trust
One of the domains where the General Data Protection Regulation (GDPR) will leave its mark prominently is the artificial intelligence industry. Data is the bread and butter of contemporary AI, and under previously lax regulations, tech companies had been helping themselves to users' data without fearing the consequences. This all changed on May 25, when GDPR came into effect. GDPR requires all companies that collect and handle user data in the European Union to be more transparent about their practices and more responsible for the security and privacy of their users. Failure to comply will result in a penalty that amounts to 20 million euros or four percent of the company's revenue, whichever is greater.
Project Hydrogen Unites Apache Spark with DL Frameworks
The folks behind Apache Spark today unveiled Project Hydrogen, a new endeavor that aims to eliminate barriers preventing organizations from using Spark with deep learning frameworks like TensorFlow and MXnet. It's tough to overstate the impact that Apache Spark has had in the emergent big data field. The software not only replaced MapReduce in the Apache Hadoop stack, but it also presented a unified framework for running data transformation, machine learning, SQL query, and streaming analytic workloads. However, the elegance of Spark's "single framework" approach breaks down when one tries to plug other distributed machine learning frameworks into the loop. While Spark MLlib provides solid machine learning functionality, the data science field is moving extraordinary fast and many data scientist want to explore the capabilities of emerging deep learning frameworks, such as TensorFlow, Keras, Caffe2, MXnet, and others.
AI and health care โ Saroj Humagain โ Medium
AI has the ability to gather tons of data and learn from it. Creating the more predictive models AI is booming the stakes. All of this ability of AI has the potential of changing the healthcare industry. Big data and well trained AI system can improve the patient diagnosis, precision medicine, patient data security, clinical decision support and many more. When it comes to AI, we always talk about the rise of intelligent robots and taking our jobs.
DeepMind's latest AI breakthrough is its most significant yet
The firm's latest Go-playing system not only defeated all previous versions of the software, it did it all by itself. "The most striking thing for me is we don't need any human data anymore," says Demis Hassabis, the CEO and co-founder of DeepMind. While the first version of AlphaGo needed to be trained on data from more than 100,000 human games, AlphaGo Zero can learn to play from a blank slate. Not only has DeepMind removed the need for the initial human data input, Zero is also able to learn faster than its predecessor. David Silver, the main programmer on DeepMind's Go project, says the original AlphaGo that defeated 18-time world champion Lee Sedol 4-1 required several months of training.
AI is acquiring a sense of smell that can detect illnesses in human breath
Artificial intelligence (AI) is best known for its ability to see (as in driverless cars) and listen (as in Alexa and other home assistants). My colleagues and I are developing an AI system that can smell human breath and learn how to identify a range of illness-revealing substances that we might breathe out. The sense of smell is used by animals and even plants to identify hundreds of different substances that float in the air. But compared to that of other animals, the human sense of smell is far less developed and certainly not used to carry out daily activities. For this reason, humans aren't particularly aware of the richness of information that can be transmitted through the air, and can be perceived by a highly sensitive olfactory system.
