Literally speaking, as the exercise solution explains, it does improves around 5% in comparison to the dummy higher frequency classifier.
Is this a correct assumption for a day-to-day use case? I.e., would 5% improvement / 82% accuracy be reasonable for real world use cases?
On my exercise I ended up concluding that although it was better, it was still quite close to just predicting the higher frequency, therefore not considering it “good”.
Toughts?
