How Robots Are Getting Better at Making Sense of the World

#artificialintelligence

The papers drilled down into topics that ranged from how to make robots more conversational and help them understand language ambiguities to helping them see and navigate through complex spaces. Ben Burchfiel, a graduate student at Duke University, and his thesis advisor George Konidaris, an assistant professor of computer science at Brown University, developed an algorithm to enable machines to see the world more like humans. In the paper, Burchfiel and Konidaris demonstrate how they can teach robots to identify and possibly manipulate three-dimensional objects even when they might be obscured or sitting in unfamiliar positions, such as a teapot that has been tipped over. The research, led by Dilip Arumugam and Siddharth Karamcheti, addressed how to train a robot to understand nuances of natural language and then follow instructions correctly and efficiently.


Soon, your most important security expert won't be a person

#artificialintelligence

Automated security systems now apply AI techniques to massive databases of security logs, building baseline behavioural models for different days and times of the week; if particular activity strays too far from this norm, it can be instantly flagged, investigated, and actioned in real time. This has led firms like IBM, Amazon Web Services, Microsoft Azure, Unisys and startups like BigML, Ersatz and DataRobot and to offer machine learning as a service (MLaaS), providing API-based access to the core libraries necessary to apply machine learning techniques to large data sets. In the short term, however, AI is still on a short leash within many security environments: a recent Carbon Black survey of 410 cybersecurity researchers found that 74 percent still see AI-driven cybersecurity solutions as flawed and 70 percent said they can be bypassed by attackers. Over time, tools will become more sophisticated and ever-larger security data sets help learning algorithms add ever more nuance to their detection mechanisms.


10 Algorithms Machine Learning Engineers Need To Know About 7wData

#artificialintelligence

Where Artificial Intelligence aims to make computers smarter and intelligent, Machine Learning has come up with ways to do that. With the use of algorithms, that iteratively learn from data, machine learning improves the functionality of computers without being explicitly programmed. If you are a Data Scientist or a machine learning passionate, you can work your way around machine learning projects using categories in which the algorithms of machine learning have been broken down. All three techniques are employed in the ten common machine learning algorithms.


Big Data and Machine Learning

#artificialintelligence

Gary Angel, Principal, Advisory Services, Advanced Analytics - Digital Analytics, EY, Digital Analytics Center of Excellence Considered one of the leading digital measurement experts in the world, Gary leads EY's Digital Analyt... With machine learning you just dump all your data into a fancy algorithm and everything gets sorted out. Supervised machine learning techniques require data that tells them what the right answer is. Many traditional machine learning techniques like regression and clustering don't handle this type of data well. How much data you have, whether you have a "right" answer, and how your data is structured all make an important difference in the potential for machine learning and appropriate machine learning technique to use.


Using AI for new visual storytelling techniques in VR

#artificialintelligence

Two frequently used techniques are generative adversarial networks (GANs), which can generate visually realistic images, and style transfer, which can turn photos or videos into works of art by applying the artistic qualities of one image style -- such as a painting -- to other images and videos. Evaluating the quality of generated images and effects by AI models is a complicated task for researchers, since there is no clear metric of success. We selected 17 target styles in total, modeled after paintings by Julien Drevelle -- whose artwork also appears in the film -- and corrupted noise images. Our style transfer algorithm was compact enough to work on a mobile phone, but we needed to scale style transfer to a professional VR setting.


Machine Learning Popularity Grows

#artificialintelligence

Both machine learning (ML) and deep learning (DL) have been successfully used for image recognition in autonomous driving, speech recognition in natural language processing applications, and for multiple uses in the health care industry. In that sense, there is an opportunity both in the IP for supplying various engines that do this, and in fact, also in the tools -- just as EDA supplies tools that allow people to build traditional, non-statistical computing systems. Deep learning adds multi-layer artificial neural networks to applications involving large amounts of input data and draws inferences that can be applied to new data. So the combination of vectors from the design input is increasing, in addition to multiple switching scenarios and multiple ports.


Hacker-Proof Coding

Communications of the ACM

The radiotherapy system team uses powerful verification methods ranging from automated theorem proving tools to manual proofs written by hand and checked by a proof assistant (a program that checks the correctness of proofs in expressive logic). To do this, DeepSpec is building tools for verifying that programs conform to deep specifications--granular, precise descriptions of how software behaves based on formal logic and mathematics--and that software components such as OS kernels provably conform to their deep specifications. Another DeepSpec member, Yale University computer science professor Zhong Shao, along with a team of researchers there, wrote an operating system called CertiKOS which uses formal verification to ensure the code behaves exactly as is intended. DeepSpec is building tools for verifying programs, and software components such as OS kernels, conform to deep specifications.


Lasers reactivate 'lost' memories in mice with Alzheimer's

New Scientist

They genetically engineered mice with neurons that glow yellow when activated during memory storage, and red when activated during memory recall. But in the Alzheimer's mice, different cells glowed red during recall, suggesting that they were calling up the wrong memories. Using a genetic engineering technique called optogenetics, Denny's team went on to reactivate the lemon-shock memory in the Alzheimer's mice. The next step will be to confirm that the same memory storage and retrieval mechanisms exist in people with Alzheimer's disease, because mouse models do not perfectly reflect the condition in humans, says Martins.


Why businesses should pay attention to deep learning

#artificialintelligence

I think the future of Alluxio is much brighter when you flip the adjective and the noun and say that it's actually a storage-backed distributed memory system, a shared memory. For example, not every company has an image-recognition problem of scale, but I'll bet every company has transactional data, time series, a transaction log. Let's divide the world into before deep learning on time series and after deep learning on time series. With deep learning, particularly recurrent neural networks like Long Short-term Memories (LSTM), relatively new applied techniques that can model time series in a much more natural way, you don't have to specify arbitrary windows.


How Artificial Intelligence benefits companies and ups their game

#artificialintelligence

Royal Bank of Scotland (RBS) launched Luvo, a natural language processing AI bot which answers RBS, Natwest and Ulster bank customer queries and perform simple banking tasks like money transfers. Compared to the progress of natural language processing solutions, computer vision-based AI solutions are still in developmental stage, primarily due to the lack of large, structured data sets and the significant amount of computational power required to train the algorithms. Other than online and IT companies, which are early adopters and proponents of various AI technologies, banks, financial services and healthcare are the leading non-core technology verticals that are adopting AI. AI, thus, can go beyond changing business processes to changing entire business models with winner-takes-all dynamics.
