Powerful antibiotics discovered using AI

#artificialintelligence

A pioneering machine-learning approach has identified powerful new types of antibiotic from a pool of more than 100 million molecules -- including one that works against a wide range of bacteria, including tuberculosis and strains considered untreatable. The researchers say the antibiotic, called halicin, is the first discovered with artificial intelligence (AI). Although AI has been used to aid parts of the antibiotic-discovery process before, they say that this is the first time it has identified completely new kinds of antibiotic from scratch, without using any previous human assumptions. The work, led by synthetic biologist Jim Collins at the Massachusetts Institute of Technology in Cambridge, is published in Cell1. The study is remarkable, says Jacob Durrant, a computational biologist at the University of Pittsburgh, Pennsylvania.

Causality based Feature Fusion for Brain Neuro-Developmental Analysis

REPLACE THIS LINE WITH YOUR PAPER IDENTIFICATION NUMBER (DOUBLE - CLICK HERE TO EDIT) 1 Abstract -- Human brain development is a complex and dynamic process that is affected by several factors such as genetic s, sex hormones, and environmental changes . A number of recent studies on brain development have examined functional connectivity (FC) defi ned by the temporal correlation between time series of different brain regions. We propose to add the directional flow of information during brain maturation . To do so, w e extract effective connectivity (EC) through Granger causality (GC) for two different groups of subjects, i.e., children and young adults. The motivation is that the inclusion of causal interaction may further discriminate brain connections between two age groups and help to discover new conn ections between brain regions. The contributions of this study are three fold. First, t here has been a lack of attention to EC - based feature extraction in the context of brain development . T o this end, we propose a new kernel - based GC ( K GC) method to learn nonlinearity of complex brain network, where a reduced Sine hyperbolic polynomial ( RSP) neural network wa s used as our proposed learner . S econd, we use d causality values as the weight for the directional connectivity between brain regions . Our f indings indicate d that the strength of connections was significantly higher in young adult s relative to children. In addition, our new EC - based feature outperform ed FC - based analysis from Philadelphia neurocohort (PNC) study wi th better discrimination of the different age groups . Moreover, the fusion of these two sets of features (FC EC) improve d brain age prediction accuracy by more than 4 %, indicating that they should be used together for brain development stud ies . I NTRODUCTION uman brain development is a prolonged process that is initiated from the third gestational week (GW) to late adolescence, and presumably to the entire lifespan [ 1 ].


These are the top 15 emerging jobs of 2020, according to LinkedIn

LinkedIn also notes that Washington DC and the surrounding metros are attracting new tech talent, including cybersecurity, data science, and artificial intelligence experts, "nearly in line" with the major tech hubs of San Francisco and New York. And mid-size US metros such as Austin, Texas, Raleigh-Durham, North Carolina, and Pittsburgh, Pennsylvania, are continuing to attract tech talent thanks in part to lower costs of living and increased remote-work opportunities.


Incremental Monoidal Grammars

arXiv.org Artificial Intelligence

In this work we define formal grammars in terms of free monoidal categories, along with a functor from the category of formal grammars to the category of automata. Generalising from the Booleans to arbitrary semirings, we extend our construction to weighted formal grammars and weighted automata. This allows us to link the categorical viewpoint on natural language to the standard machine learning notion of probabilistic language model.


AI So Expansive You Can Drive A Truck Through It - RTInsights

#artificialintelligence

With full autonomy, operating costs would decline by about 45 percent, saving the US for-hire trucking industry between $85 billion and $125 billion. Just recently, it was reported that a driverless truck made a cross-country trip, running 40,000 pounds of butter from Tulare, California to Quakertown, Pennsylvania. The 2,800-mile-trip took three days. Of course, the truck did not travel entirely on its own -- a technician rode on board to keep an eye on things. But are we ready to have huge, autonomous tractor-trailers thundering down the interstates?


Army, Navy investigators find hand gestures made during football broadcast weren't racist

FOX News

President Trump and Defense Secretary Mark Esper visit the Army-Navy locker rooms to deliver words of encouragement before the 120th Army-Navy football game in Philadelphia. A probe into hand gestures flashed by West Point cadets and Naval Academy midshipmen at last weekend's televised Army-Navy college football in Philidelphia game were not racist, separate military investigations conducted by the military academies found. Clips of the "OK" hand gestures by the service-academy students during a Dec. 14, ESPN College GameDay broadcast game went viral and raised concerns over whether the signs were associated with white nationalism. The gesture, which features the thumb and forefinger that touch in a circle with the other fingers outstretched, has been appropriated as a signal for white supremacy in recent years. The Naval Academy found that two of its midshipmen were participating in a "sophomoric game" and had no racist intent behind the hand signs.


A Self-Driving Truck Delivered Butter from California to Pennsylvania in Three Days

#artificialintelligence

An autonomou truck from startup Plus.ai took three days to drive 2,800 miles, from Tulare, CA, to Quakertown, PA, to deliver 40,000 pounds of butter for Land O'Lakes. Startup Plus.ai has completed what is being called the first commercial freight cross-country trip by an autonomous truck, a 2,800-mile-run from Tulare, CA, to Quakertown, PA, that took three days to deliver 40,000 pounds of butter for Land O'Lakes. A human safety driver was aboard the autonomous 18-wheeler to take over if needed, accompanied by a safety engineer. The company said the trip was a smooth one with zero "disengagements," which occur when a self-driving system has to be suspended because of a problem. Ten to 15 companies in the U.S. are working on autonomous freight delivery, said Dan Ives of Wedbush Securities, who believes the trucking industry will be the first to adopt autonomous technology on a mass scale.


Faces of digital health

The idea that AI will replace radiologists comes from the fact that today's AI models models are very good at pattern recognition. The interesting thing in radiology are the NLP models mining radiology reports,says Woojin Kim, Chief Medical Information Officer at Nuance, former Chief of Radiography Modality, Director of Center for Translational Imaging Informatics, Associate Director of Imaging Informatics, and Assistant Professor of Radiology at the Hospital of the University of Pennsylvania.


Self-driving truck completes FIRST EVER cross-country trip from California to Pennsylvania

Daily Mail - Science & tech

A self-driving truck has completed the first cross-country commercial freight run. Plus.ai, announced its truck traveled 2,800 miles autonomously from California to Pennsylvania hauling a fully-loaded refrigerated trailer of perishable cargo. The vehicle is fitted with advanced autonomous driving system that utilizes multimodal sensor fusion, deep learning visual algorithms and simultaneous location and mapping (SLAM) technologies. The truck drove in autonomous mode across interstate 17 and interstate 70, while traveling through different terrains and weather conditions. Although a safety driver and engineer were on-board, this journey, according to Plus.ai, validates'the system's ability to safely handle a wide range of weather and road conditions.'
