Through training, they assign numerical values to determine which features are most important. These values are called model weights. <br><br>With millions\u2014or even billions\u2014of such parameters, weights shape how AI generates text, recognizes images, or makes predictions.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 id=\"%f0%9f%8e%af-everyday-analogies\" class=\"wp-block-heading\"><strong>\ud83c\udfaf Everyday Analogies<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-medium-font-size\">\ud83c\udfb9 <strong>Music<\/strong>: Imagine AI as a pianist and the sheet music as its architecture.
