Four miles north of Los Altos is the Googleplex. Seven more miles brings you to Facebook’s headquarters, and eight miles south is the Apple Campus — welcome to the Silicon Valley. Mall cop robots are commonplace, and we see self-driving cars everywhere. While the rest of the world views such cars as incredible feats of technology, many in the area see them as less of a feat and more of a nuisance to drive behind when in a rush. Self-driving cars are not only one of many science-fiction-esque technologies that we take for granted but also perhaps the most widely known application of machine learning. Machine learning is a subfield of artificial intelligence (AI) that allows computers to make decisions without being explicitly programmed. It uses pattern recognition to learn from large sets of data and apply “knowledge” to new tasks based on previous situations. Machine learning is versatile and applicable to a variety of subjects and professions. It is the Silicon Valley’s newest tech craze, and it should not be dismissed as a mere nuisance.
