Expected Improvement

Expected Improvement (EI) is a strategy used in decision-making, particularly in optimization problems and machine learning. It estimates how much better a potential choice might perform compared to the current best option. By evaluating different possibilities, EI helps identify which option is most likely to yield the greatest improvement. In essence, it guides you to make smarter choices by focusing on actions that have the best chance of enhancing outcomes, balancing exploration of new possibilities with leveraging existing knowledge.
