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...
Question 1: What are your thoughts on machine learning and the role it will play in the data center space? Machine learning has already had a profound impact on some of the larger enterprises that have the scale and resources to not only develop but deploy Machine Learning across their da...
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....
