⭐⭐⭐⭐⭐
score is between 0 and 5
Optimization algorithms in machine learning are mathematical procedures used to adjust the parameters of models to minimize or maximize a specific objective function, such as loss or error. These algorithms are essential for training machine learning models effectively, enabling them to learn patterns from data and improve performance over time. Common optimization techniques include gradient descent, stochastic gradient descent, Adam, RMSprop, and advanced methods like second-order approaches and evolutionary algorithms.
