👉 Semidigitigrade is a term used in mathematics and computer science to describe a mathematical or computational model that has both positive and negative outputs for inputs. It's often used in fields such as machine learning, where it helps in creating models with both positive and negative examples. For example, the semidigitigrade function could be represented mathematically as: f(x) = x^2 - 1 This function takes a real number as input and returns its square minus one.
