Yes. Nevertheless, P(H|E) still equals (P(E|H)*P(H))\/P(E). That is somewhat of an inconvenient truth, but that is the way it is.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">We move onward as Intel creates yet another generation of processors with more multiplications per second at a lower $ per everything. With this, <em>n<\/em> becomes larger, hardware budgets fall, and some of those equations become possible. That is, of course, if we understand those equations in the back of that green hardback book.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In my opinion\u2014this is, after all, my blog\u2014you cannot be a data scientist without knowing who Duda and Hart are and what they did. Then again, I am old\u2014apparently too old to be hired in such a new profession as Data Scientist.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>by Dwayne Phillips Are you a data scientist?
