Probability & Naïve Bayes Classifier

Probability is simply how likely something is to happen. Whenever we’re unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are. The analysis of events governed by probability is called statistics.   The best example for understanding probability is flipping a coin: There are two possible outcomes—heads or tails. What’s the probability of the coin landing on Heads? We can find out using the equation  P(H) = ? P ( H ) = ? P, left parenthesis, H, right parenthesis, equals, question mark .You might intuitively know that the likelihood is half/half, or 50%.  But how do we work that out?  Probability = Formula for calculating the probability of certain outcomes for an event In this case: Probability of a coin landing on heads Probability of an event = (# of ways it can happen) / (total number of outcomes) P(A) = (# of ways A can happen) / (Total number of outcomes) Example 1 There are six different outcomes. Differ...

AI Definitions

Artificial Intelligence Humankind has given itself the scientific name  homo sapiens --man the wise--because our mental capacities are so important to our everyday lives and our sense of self.  The field of  artificial intelligence , or AI, attempts to understand intelligent entities. Thus, one reason to study it is to learn more about ourselves. But unlike philosophy and psychology, which are also concerned with intelligence, AI strives to  build  intelligent entities as well as understand them. Another reason to study AI is that these constructed intelligent entities are interesting and useful in their own right. AI has produced many significant and impressive products even at this early stage in its development. Although no one can predict the future in detail, it is clear that computers with human-level intelligence (or better) would have a huge impact on our everyday lives and on the future course of civilization. What is AI? We have now explained why AI is...

Introduction to Artificial Intelligence

Introduction to Artificial Intelligence Artificial Intelligence is simply the ability of a computer to exhibit “intelligence”. This intelligence can either mimic human intelligence or observe real-world problems and intelligently find solutions for them.
