喜樂美語
  1. 1(數學/AI)張量; (解剖學)張肌

    This word shows up in two very different places. In math, physics, and especially in AI/computer science, a tensor is a way of organizing numbers into a grid that can have many dimensions - it could be just one number, a list, a table, or something even bigger. You've probably heard the word from 'TensorFlow,' a famous tool for building AI. In the human body, a 'tensor' is a muscle whose job is to pull something tight or straight, like the tensor muscle near your hip.

組成From the Latin word 'tendere,' meaning to stretch. A tensor is something that stretches or makes tight.

同家族的字
