Optimization in Machine Learning

Optimization is a fundamental aspect of machine learning, closely tied to the efficiency and accuracy of models. This chapter moves into the core principles of optimization, a process that involves finding the optimal solution from a set of possible choices. You will look into how calculus, particularly derivatives, plays an important role in refining models by adjusting parameters to minimize errors and maximize performance.

Throughout this chapter, you will get into gradient descent, a widely-used optimization algorithm that makes use of derivatives to iteratively find the minimum of a function. By examining cost functions and how they are minimized, you will learn how machine learning models are trained and improved over time. Additionally, the chapter will introduce more advanced optimization techniques, providing insights into when and how they should be used.

As you progress, you'll see how these optimization strategies are applied to real-world machine learning problems, improving your ability to not only implement models but also to fine-tune them for better results. By the end of the chapter, you'll have a strong set of tools and techniques essential for optimizing machine learning models, laying a solid foundation for further exploration in this area.
