An Association Rule is an implication of form A ⇒ B, where A ⊂ I, B ⊂ I , and A ∩B = φ. The rule A ⇒ B holds in the data set (transactions) D with supports, where ‘s’ is the percentage of transactions in D that contain A ∪ B (i.e., the union of set A and set B, or both A and B). This is taken as the probability, P (A ∪ B).By simple linear equation y=mx+b we can calculate MSE as: Let’s y = actual values, yi = predicted values. Using the MSE function, we will change the values of a0 and a1 such that the MSE value settles at the minima. Model parameters xi, b (a0,a1) can be manipulated to minimize the cost function.Pandas stores categorical variables as ‘object’ and, on the other hand, continuous variables are stored as int or float.
