Web10 mrt. 2024 · So we need to compare our models and choose the one which best suits the task at hand. Please note, accuracy need not always be the best metric to choose a model. More about this in later tutorials. Using the sklearn library we can find out the scores of our ML Model and thus choose the algorithm with a higher score to predict our output. WebPlan: Discuss the Mistake Bound model. The Mistake Bound model In this lecture we study the online learning protocol. In this setting, the following scenario is repeated inde nitely: 1. The algorithm receives an unlabeled example. 2. The algorithm predicts a classi cation of this example. 3. The algorithm is then told the correct answer.

Using the standard conversion techniques from the mistake-bound model to the PAC model, our algorithms can also be used for learning k-parities in the PAC model. In particular, this implies a slight improvement over the results of Klivans and Servedio [KS04] for learning k-parities in the PAC model.
