Over the last year, companies such asKraft HeinzandThomson Reutershave done just that. “We wanted to carve out the time and the space for employees to build knowledge and skills,” saysAbby Pinto, who leads the enterprise learning and development team at Thomson Reuters. “AI...
Everyone’s talking about machine learning these days. But what exactly is it? And will we be seeing more of it in the future? Well, we recently sat down with Raritan’s Technical Product Manager, Paul Mott, to discuss this growing trend and the potential effects it could have on the...
Put in another way, how well the model has learned true patterns versus having simply memorized the training data. Holdout data and cross-validation are effective techniques to make sure that your model isn’t just memorizing but is actually learning generalized patterns....
