What's new this week?

AI in motorsport, racing, and surfing. AI that finds relationships between people, skills, and projects. Fraud detection with Machine Learning. A new look at AI ethics, and AI that fights aging.

AI is applied in every industry nowadays, even in sports. From motosport and racing to surfing and curling, sports teams are working hard to glean actionable insights from data. This is the case with:

  • Envision Virgin Racing that takes advantage of data science to hone performance on race day. AI analyzes data and finds trends that are impossible for the human brain to detect.
  • The Olympics' surfing teams: AI generates artificial waves and helps tracks sleep and other vitals to help coaches fine-tune athletes' training and recovery.
  • Drone racing:  New control algorithms developed at the University of Zurich calculate the optimal route at every point in the flight, rather than doing it section by section, having helped them to beat experienced human pilots for the first time.

In the meantime, NASA employs AI to build a talent mapping database using Neo4j technology that shows the relationships between people, skills, and projects, to search for talent and job opportunities. The University of Surrey has built an AI model that identifies chemical compounds that promote healthy aging, paving the way towards pharmaceutical innovations that extend a person's lifespan.

Another large area of research is anomaly detection. Here we have American Express that has been experimenting with AI-generated fake fraud patterns to sharpen its models’ ability to detect rare or uncommon swindles, thus helping detect fraud more accurately.

And finally, AI ethics. To get it right, organizations should consider these six strategies: 1) remove the fear of not getting it right away, 2) tailor your message to your audience, 3) tie your efforts to your company purpose, 4) define what ethics means in an operational way, 5) lean on trusted and influential individuals, 6) never stop educating.
