(Infinite Data) Assume that your training data $\mathcal{S}=\left\{\left(\mathbf{x}_{n}, y_{n}\right)\right\}$ is iid and comes from a fixed distribution $\mathcal{D}$ that is unknown but is known to have bounded support. Assume that your family of models contains a finite number of elements and that you choose the best such element according to the training data. You then evaluate the risk for this chosen model. Call this the training risk. As $|\mathcal{S}|$ tends to infinity, this training risk converges to the true (according to the distribution $\mathcal{D}$ ) risk of the best model in this family.

purpose of which is to detect whether a tweet is offensive. For each Tweet processed, such a system outputs one of the following classes: "hateful",
"offensive" and "neutral".To perform your evaluation, you
collect a large set of Tweets and have it annotated by two human
annotators. This corpus contains 1% of "hateful" and 4% of
"offensive" Tweets.What metrics do you think are appropriate to evaluate such a system?(penalty for wrong ticks)
