In machine learning, "the task of identifying what an image represents is
called image classification"
Suppose that an image classification model is trained to recognize images of cats. This
model classifies 95% of cat images correctly (that is, it classifies them as cats) and 70% of
non-cat images correctly (that is, it classifies them as not cats). Assume that the
probability of an image being a cat is 40%.
6.1 What is the probability that an image is a cat if the model classifies it as a cat?
6.2 What is the probability that an image is a cat if the model classifies it as not a cat?
6.3 What is the probability that an image is not a cat if the model classifies it as a cat?
6.4 What is the probability that an image is not a cat if the model classifies it as not a cat?
