Logs

Introduction

Like all things I have learned or not learned, I need a pages so I can say, yes I remember this.

Going in Gaussian Naive Bayes I was redirected to logs. This showed how log number lines show the size of the differences. If for instance we take 1 and 8, 8 is 8 times the distance from 1 but if we do this with 1/8th and 1 which is also 8 times the distance the number line does not show this. But a log number line does

Fold Change is defined as Ratio that describes a change in a measured value

Second Time around

So thought I might go around this again so I to not forget. The above information is probably the useful part of all this but a simple diagram demonstrates I do know this, I just forget.

To

The logarithm of 8 in base 2 = 3
Because 2U+00B3 is 8
