Artificial Intelligence: Searching Do you know the different way AI uses for searching? A search strategy is defined by picking the order of the node expansion: Strategies are evaluated along the following dimensions: 1)Completeness Does it always find a solution if one exists? 2)Time Complexity A number of nodes generated/expanded. 3)Space Complexity Maximum no of nodes in memory 4)Optimality Does it always find the least cost Solution?                                        Time and Space complexity is measured in terms of B: Maximum branching factor if the search tree D:Depth of the solution M: maximum depth of the state space(maybe infinity) Type of Searches available: Uninformed Search are the search agent that do not require domain knowledge to search through the search space. Breadth First search are the type of the search...

Logistic Regression Let’s first understand what is Regression Analysis? Regression analysis is a technique in which we predict value of independent variable given the value of dependent variable. It is a predictive modelling technique and estimates the relation between a dependent and an independent variable that we need to predict. Regression is classified in three types:- 1.     Logistic Regression 2.     Linear Regression 3.     Polynomial Regression Logistic Regression produces result in binary format which is used to predict the outcome of a categorical dependent variable. So, the outcome should be discrete/categorical such as: ·        0 or 1 ·        Yes or No ·        True or False ·        High and Low We use logistic regression when we need the output to be in ...
