💡Calculus
Calculus is a branch of mathematics that deals with the study of change and motion, focusing on the concepts of limits, derivatives, integrals, and infinite series. In the context of the video, calculus is foundational for understanding how to optimize machine learning algorithms, as it provides the mathematical framework for computing derivatives which are essential for learning from training data.
💡Limits
Limits are a fundamental concept in calculus that describe the behavior of a function as its input approaches a certain value. They are used to define continuity, derivatives, and integrals. In the video, limits are introduced as a prerequisite for understanding differentiation, which is critical for machine learning algorithms to learn from data.
💡Derivatives
Derivatives in calculus represent the rate at which a quantity changes with respect to another quantity. They are crucial for optimization and are used to find the maximum or minimum values of functions. In the video, derivatives are key to machine learning as they form the basis of algorithms like backpropagation and stochastic gradient descent.
💡Differentiation
Differentiation is the process of finding the derivative of a function. It is a method used to analyze the sensitivity of the output of a function to a small change in its input. In the video, differentiation is central to the study of calculus as it is the primary means of computing derivatives, which are essential for optimizing machine learning models.
