Shannon Entropy Calculator. Enter the string: Calculate. Named after Claude Shannon, the father of information theory, this calculator applies the principles of Shannon’s entropy formula to quantify the average amount of information contained in each event or symbol within a dataset.
Entropy Calculator: Accurate Thermodynamics Results Online. Use this entropy calculator to determine the level of disorder or randomness in a system based on your input values.
In terms of your particular question on potential use of standard deviation (SD) as a substitute measure for decision trees, I have to say the following: yes, it is possible to use SD as a substitute for entropy (information gain, to be more accurate);
How to Calculate Shannon Entropy. Exactly how you calculate entropy is very field specific. For example, you wouldn’t calculate nutrition in the same way you calculate entropy in thermodynamics. However, all formulas are based on Shannon’s original metric, which was calculated as follows: Where: H = Shannon Entropy,

Jan 25, 2014 · Entropy and Standard Deviation are certainly not the same, but Entropy in most cases (if not all) depends on the Standard Deviation of the distribution. Two examples: For the Exponential distribution with density function λe − λx, x ≥ 0, SD = 1 / λ we have. H(X) = 1 − lnλ = 1 + lnSD.
