28. Neural Networks

#artificialintelligence

In the context of this course, we view neural networks as "just" another nonlinear hypothesis space. On the practical side, unlike trees and tree-based ensembles (our other major nonlinear hypothesis spaces), neural networks can be fit using gradient-based optimization methods. We discuss the specific case of the multilayer perceptron for multiclass classification, which we view as a generalization of multinomial logistic regression from linear to nonlinear score functions.


Focus on 'Augmented Intelligence' for next level of digital transformation: Analyst- Technology News, Firstpost

#artificialintelligence

Companies should focus on "Augmented Intelligence", digital product management, and in creating a digital twin of an organisation (DTO) for their next level of digital transformation and boost in growth, a top Gartner analyst has said. Augmented Intelligence is the step beyond Artificial Intelligence (AI), where you marry AI with human capability, Partha Iyengar, Vice President and Gartner Fellow, told IANS in a telephonic interaction. The concept refers to the implementation of AI not just as a replacement of human work through automation, but as a means to augment their abilities. "Augmented Intelligence could be applied across processes, across verticals and even across job functions," Iyengar said, adding that some organisations in India, including Indian Oil, have already started focusing on AI augmentation in a big way. Globally, Singapore is at the forefront of implementing AI augmentation, according to Iyengar.

Concise Research Paper :: Four Laws of Artificial Intelligence (AI)

#artificialintelligence

Nobody can predict future correctly. Present is outcome of past and future is outcome of present. Present, past and future--all three events--lie on the same straight line. Keeping this in mind--three laws of Robotics--pioneered by Russian Scientist--Isaac Asimov is incomplete one and therefore, I humbly challenge Isaac Asimov and propose Four Laws of AI (FLAI)--which encompass robotics just as one of the branch of AI and borrows some of the concepts from Asimov as well. It also incorporate nature and harmony of universe--to be fully align with natural laws of universe.


Head of R&D Jia Li Leaves Google Cloud AI

#artificialintelligence

Head of R&D of Google Cloud AI Jia Li has left her position with the company. Li informed Synced in a text message yesterday and the Google team confirmed her departure this morning. An Adjunct Professor at Stanford University's School of Medicine and a widely respected AI researcher, Li told Synced "I'm now pursuing the impact of AI for good in healthcare and working full-time at Stanford University's AIMI (Center for Artificial Intelligence in Medicine & Imaging). In healthcare, I am interested in how AI can improve the outcomes of individual patients as well as hospitals." Chinese media is reporting that Li will start her own AI company with the aim of bringing machine learning solutions to the healthcare industry; and that a number of leading global venture capitals are interested.


The Human Brain Is a Time Traveler

#artificialintelligence

Randy Buckner was a graduate student at Washington University in st. Louis in 1991 when he stumbled across one of the most important discoveries of modern brain science. For Buckner -- as for many of his peers during the early '90s -- the discovery was so counterintuitive that it took years to recognize its significance. Buckner's lab, run by the neuroscientists Marcus Raichle and Steven Petersen, was exploring what the new technology of PET scanning could show about the connection between language and memory in the human brain. The promise of the PET machine lay in how it measured blood flow to different parts of the brain, allowing researchers for the first time to see detailed neural activity, not just anatomy. In Buckner's study, the subjects were asked to recall words from a memorized list; by tracking where the brain was consuming the most energy during the task, Buckner and his colleagues hoped to understand which parts of the brain were engaged in that kind of memory. But there was a catch. Different regions of the brain vary widely in how much energy they consume no matter what the brain is doing; if you ask someone to do mental math while scanning her brain in a PET machine, you won't learn anything from that scan on its own, because the subtle changes that reflect the mental math task will be drowned out by the broader patterns of blood flow throughout the brain. To see the specific regions activated by a specific task, researchers needed a baseline comparison, a control. At first, this seemed simple enough: Put the subjects in the PET scanner, ask them to sit there and do nothing -- what the researchers sometimes called a resting state -- and then ask them to perform the task under study.


Artificial Intelligence Makes Waves in Breast Cancer Research & Awareness Your Medical Imaging Cloud Ambra Health

#artificialintelligence

We're excited to share an interview with Dr. Mark Traill, who is the owner of MammoBot LLC. Mammobot is a cloud-based startup that offers a double reading of screening 2D or 3D mammograms using artificial intelligence algorithms. Clients can upload mammogram studies that become part of the investigational protocol prior to pending FDA approval of the algorithm. Review of the mammogram study by AI algorithms has the potential of detecting early breast cancer that was missed on the initial human review of images. Ambra Health: When did Mammobot begin?


Artificial Intelligence In Healthcare - Can It Replace The Doctor?

#artificialintelligence

Just imagine a scenario wherein with your MRI of the knee joint, a software can predict your risk of developing a disease like osteoarthritis, based on pattern profiling of million of other MRIs to predict whether you are at risk and also offer preventive options for the same. A new kind of doctor has entered the consultation chamber but doesn't have a name. In fact, these doctors don't even have faces. Artificial intelligence has made its way into hospitals around the world or maybe just, in the near future. Artificial Intelligence (AI) is a general term that implies the use of a computer to model intelligent behaviour with minimal human intervention.


Weapons Upgraded for Third Annual Hill City Robot Battle

U.S. News

Some battles saw pieces of robots smashed off during collisions causing the audience watching on the ground and the upper level to shout. After really destructive battles, someone would use a broom to brush the pieces to the side so competitors could gather their bots scattered remains.
