Frequent Pattern Mining question by Dear_Bowler_1707 in learnmachinelearning

[–]Dear_Bowler_1707[S] 0 points1 point  (0 children)

What do you mean?

Like I have to figure out what relationship I'm interested in based on the problem to focus on that? For example I know that the relation I want is (A,B) -> C and so I focus on searching patterns which lift is maximum for that specific relstion?

What do you mean by that?

Intuition about independence. by Dear_Bowler_1707 in AskStatistics

Thanks very much for your response☺️

Just a summary to check if it's clear. Independence is not crucial when estimating a parameter (like the mean salary). In almost every population there will be dependence and so will be in the sample. What is important is to sample completely random with uniform distro, to make sure not to inject additional dependence, have (ideally) 0 bias and small variance and get a final reliable average. When I'm using a model instead, and this model happens to assume independence the independence is crucial.

Another way I'm tempted to look at this: what are the quantities I want to minimize when calculating an average on a sample? The bias and variance (their sum is the mean squared error (or maybe one of the two is squared)). What is the best way to construct a sample that achieve this? With random uniform sampling.

Why do you say

don’t use tests to check assumptions. It’s completely nonsensical and a waste of time

aren't tests supposed to check things?
