The surface tension of water is a phenomenon that uses between water molecules (but not the air molecules above) to allow certain organisms to walk across water. 

*What size is the following matrix? Also, is it a square matrix, a column matrix, a row matrix, or none of those? 457{“version”:”1.1″,”math”:”457″} Your answer:  This matrix is a ____ x ____ matrix. It is a _________ matrix. The first two blanks should be filled in with numbers. The third blank should be filled in with one of the following words (or the blank should be left empty if none of these choices are appropriate): square, column, row. 

A witch’s house contains bats and spiders. In total, there are 23 creatures in her house (not counting herself). Altogether, these creatures have 112 legs. Every bat has two legs and every spider has eight legs.  How many bats and how many spiders are in the witch’s house? Fill in the blanks to give me your answer: The farmhouse contains _____ bats and ____ spiders. You must set up a linear system. You may then solve that linear system by any method. I want to see your work for this problem. If you solve the problem using matrices and your calculator, the work I want to see will include the following: the matrix that you put into the calculator, the matrix that you get from the calculator, and also your answer. (That’s three things you must show.) You will need to submit your work for this problem to the Dropbox folder “Work for Test #2”. Failure to follow these instructions will mean that you will get 0 points for this problem, even if you have the right answer.  For example, simply guessing what the answer should be is worth 0 points.

Which type of a and a transfer function is described: operation increases in a line based on condition using an operation such as a=n.

Naïve Bayes is a simple probability-based classification method derived from the Bayes theorem.

Backpropagation requires the of vector pairs, with the pairs consisting of:

Compared to the human brain, artificial neural networks have many more neurons.

Deep neural networks are referred to as “deep” because they are primarily used to evaluate significant philosophical issues.

Which of the following is not a foundation of AI?

The Naïve Bayes method is a powerful tool for representing dependency structure in a graphical, explicit, and intuitive way.
