If you are looking for an answer to the question What is Artificial Intelligence? and you only have a minute, then here's the definition the Association for the Advancement of Artificial Intelligence offers on its home page: "the scientific understanding of the mechanisms underlying thought and intelligent behavior and their embodiment in machines."
However, if you are fortunate enough to have more than a minute, then please get ready to embark upon an exciting journey exploring AI (but beware, it could last a lifetime) …
At this point, we all know of XGBoost due to the massive success it has had in numerous Data Science competitions held on platforms like Kaggle. Along with its success, we have seen several variations such as CatBoost and LightGBM. All of these implementations are based on the Gradient Boosting algorithm developed by Friedman¹, which involves iteratively building an ensemble of weak learners (usually decision trees) where each subsequent learner is trained on the previous learner's errors. Let's take a look at some general pseudo-code for the algorithm from Elements of Statistical Learning²: However, this is not complete! A core mechanism which allows boosting to work is a shrinkage parameter that penalizes each learner at each boosting round that is commonly called the'learning rate'.
The Feinstein Institutes for Medical Research has spun out a startup whose artificial-intelligence device could help paralyzed patients regain the use of their hands. Earlier this month, the startup, Neuvotion Inc., announced a $1.1 million funding round from the Long Island Angel Network and the Good Shepherd Rehabilitation Network based in Allentown, Pennsylvania. The Darien, Connecticut, startup is in the process of transferring research developed in the laboratory of Chad Bouton, vice president of advanced engineering at the Feinstein Institutes, a unit of Northwell Health. Bouton also is founder of Neuvotion. The company's initial device, NeuStim, is worn as a patch on the patient's forearm and is being positioned for use in clinics and at home.
Breastfeeding can have long-term cognitive benefits for the mother, a new study has found. Researchers at the University of California, Los Angeles, conducted a study that found women over the age of 50 who had breastfed their babies performed better on cognitive tests compared to women who had never breastfed. "While many studies have found that breastfeeding improves a child's long-term health and well-being, our study is one of very few that has looked at the long-term health effects for women who had breastfed their babies," Molly Fox, the study's author, said in a news release. "Our findings, which show superior cognitive performance among women over 50 who had breastfed, suggest that breastfeeding may be'neuroprotective' later in life," she added. The study, titled, "Women who breastfeed exhibit cognitive benefits after age 50," asserts that breastfeeding's biological effects and psychosocial effects, such as improved stress regulation, could exert long-term benefits for the mother's brain.
Torc Robotics and Daimler Truck kick off their third year of partnership poised to commercialize the first scalable, profitable Level 4 autonomous truck that will help fleets improve their operations while bolstering the backbone of the U.S. economy. Torc is currently testing the Level 4 trucks on public roads in Virginia, New Mexico, and Texas, with continued route expansion in the works. The two companies are pursuing a focused, safety-oriented approach to market that also seeks to build trust among fleets and the drivers of vehicles who will share the road. Introducing a world-changing technology into an existing infrastructure, where human drivers will share the road with automated trucks, requires credibility and responsibility, according to Dr. Peter Vaughan Schmidt, Head of Daimler Truck's Autonomous Technology Group. "As the inventor of the truck, Daimler Truck has many decades of experience in testing and validation of commercial vehicles. Nevertheless, to develop a safe autonomous level 4 truck remains a complex task and resembles a marathon, not a sprint. Two years together with Torc Robotics, we have accomplished a lot, collaboratively pursuing a common goal of leading the logistics sector into the future and making road traffic safer for society. I am convinced that we are optimally positioned as a company and together with Torc we have the right partner at our side to achieve our goals."
