👉 Approximation is a process of finding an exact match between two sets of values, or in other words, comparing them to achieve consistency. It involves using algorithms and mathematical theories to approximate the value of one variable with respect to another. In the context of machine learning, approximations are used to find the best fit for a model based on its predictions. Approximation is crucial in many fields such as artificial intelligence (AI), computer vision, natural language processing, speech recognition, and more. It helps
