Logistic regression tuning parameters

WitrynaTwo Simple Strategies to Optimize/Tune the Hyperparameters: Models can have many hyperparameters and finding the best combination of parameters can be treated as a search problem. Although there are many hyperparameter optimization/tuning algorithms now, this post discusses two simple strategies: 1. grid search and 2. WitrynaIn the context of Linear Regression, Logistic Regression, and Support Vector Machines, we would think of parameters as the weight vector coefficients found by the learning algorithm. On the other hand, “hyperparameters” are normally set by a human designer or tuned via algorithmic approaches.
