Does the preprocessing of one algorithm change the conditions of the experiment? Question: As an example, We have two algorithms that utilize the same dataset and the same train and test data: 1 – uses k-NN and returns the accuracy; 2 -applies preprocessing before k-NN and adds a few more things, before returning the accuracy. …

Thus PYTHON conforms well to the Type Completeness Principle. I still didn’t get it. Asked By: Still Learning || Source Answers: The Type Completeness Principle: No …
"Flat is better than nested" – for data as well as code? Question: This question got me thinking: should we apply the principle that “flat is better than nested” to data as well as to code? Even when there is a “logical tree structure” to the data? In this case, I suppose it would mean …
