WHAT IS MACHINE LEARNING?

-

Machine learning is a branch QH CTVKƂEKCN KPVGNNKIGP­EG VJCV borrows heavily from other ƂGNFU UWEJ CU UVCVKUVKEU mathematic­s, physics and theoretica­l computer science. Machine-learning algorithms enable computers to perform tasks without human interventi­on. With this technique, machines can be taught to make their own programs. Every time you ask your virtual assistant Alexa QT 5KTK VQ RGTHQTO C URGEKƂE task, that’s machine learning in action.

More complex uses of machine learning include KOCIG ENCUUKƂECV­KQP (QT example, Adobe has developed a feature called Smart Tags for its program Experience Manager. It can add tags to images automatica­lly. For example, to an image of the Washington Memorial, it would slap tags such as ‘architectu­re’, ‘memorial’, and ‘Washington Memorial’. If someone searched for architectu­re images on their system, the Washington Memorial photo would show up. AI art tools developed by Mario Klingemann, Dan Ventura and Simon Colton all make use of machine learning.
