Financial Services

Advanced AI to Help Prevent Credit Card Fraud

Visa is launching a platform to help its engineers quickly test AI algorithms designed to detect and prevent credit card fraud. The platform is an example of the broader financial services industry trend toward using AI to detect patterns in transactions that could be a sign of criminal behaviour. The new platform, which is cloud-based, will test algorithms that use deep learning to sift through data to find anomalies in an effort to prevent fraudulent transactions that involve billions of dollars every year.

AI to Help Manage Elevated Blood Sugar During Surgery

Researchers at the University of Washington in Seattle have built a new AI tool that can predict, prior to surgery, which patients will have the problem of elevated glucose levels while under the knife. The researchers built and validated several separate prediction tools using a dataset of perioperative records from more than 6,500 patients. Comparing the tools against one another, the team found all those using machine learning were more accurate than a conventional linear regression model. The best of the machine-learning algorithms, an extreme gradient boosting model, had the smallest median prediction error and the narrowest interquartile error range. Read More

Healthcare

AI to Help Prevent Sepsis

Sentara Healthcare is now deploying AI to use vital medical data to stop patients from contracting life-threatening sepsis. The new AI tool grabs about 4,500 pieces of data about a patient that live in the electronic record — body temperature, heart rate, blood tests, past medical history, gender, where they live and so on — and runs it all through an algorithm that assesses risk for developing sepsis. If a patient is deemed high risk, the tool spits out an alert that notifies a doctor or nurse the next time they open the medical chart. The alert also links to clinical guidance to help the provider determine what to do next. Read More

Healthcare

AI to Help Spot Brain Aneurysms

GE Healthcare signed on to a new Australian research collaboration to develop AI tools to quickly and automatically diagnose brain aneurysms. The AI algorithm will be trained to look for abnormalities within the brain including in blood vessels within the circle of Willis, the arterial ring at the base of the brain. The system also will be designed to help track and monitor aneurysms over the long term. An additional focus of the project will include a surgical planning tool for intervention with a stent and applying fluid modeling to predict the risk of rupturing the aneurysm. Read More

AI to Help Protect Bananas from Diseases and Pests

A new smartphone tool called Tumaini helps banana farmers scan plants for signs of five major diseases and one common pest. To build it, researchers uploaded 20,000 images that depicted various visible banana disease and pest symptoms. With this information, the app scans photos of parts of the fruit, bunch, or plant to determine the nature of the disease or pest. It then provides the steps necessary to address the specific disease. In addition, the app also records the data, including geographic location and feeds it into a larger database. Read More

AI Validates Evolution's Oldest Mathematical Model

Researchers from the UK and Japan have used modern AI to validate what is considered evolutionary biology's oldest mathematical model – that of Müllerian mimicry. The team from the University of Cambridge, the University of Essex and the Natural History Museum, from the UK along with the Tokyo Institute of Technology used a machine learning algorithm to test whether butterfly species can co-evolve similar wing patterns for mutual benefit. Using 2,400 photographs from the Natural History Museum, they trained their algorithm, ButterflyNet, to quantify variations between different subspecies. The researchers found that Müllerian mimicry can generate entirely new patterns by combining features from different lineages. Read More
