14 – Solution Sensitivty And Specificity

Let me use these medical words because it makes sense. A algorithm is deemed to be sensitive to cancer if it finds cancer. So to make your algorithm maximally sensitive, you classify everything as cancer. And it finds all the cancer, it gets 100 percent sensitivity. Now, that’s not a good algorithm, because now you cut out every single mole you find. The opposite of this is specificity, and so you want 100 percent specificity because you only want to send things so the lab that are actually cancer.
