binary jensen shannon divergence calculator online

Use binary jensen shannon divergence online for p p, q p. Equal mixture and probabilities strictly inside the unit interval. Finite floating-point calculation with the displayed domain; large integer counts can lose exact precision.

How to use it

Enter p p. Set q p. Select Calculate and check the labeled output. Copy or download the JSON result.

Options and example settings

OptionChoices / valueExample default
p pMain input. Zero or positive values. Maximum 1.0.3
q pOption. Zero or positive values. Maximum 1.0.7

Calculation method

divergence_bits = (entropytwo(p_p,(p_p+q_p)/2)+entropytwo(q_p,(p_p+q_p)/2))/2 (^ means exponentiation; trig functions ending in d use degrees).

Worked examples

Apply binary jensen shannon divergence to the case below, keeping the displayed units and assumptions. Equal mixture and probabilities strictly inside the unit interval.

Binary Jensen Shannon Divergence — worked case

Settings: q p: 0.7

Input:

0.3

Calculated result for these inputs:

Output:

{
  "divergence_bits": 0.11870910076930731
}

Choose the right tool

Choose number theory for exact integer relationships, distribution tools for a declared random model, and geometry tools for coordinates. A density is not a probability and a statistical model does not establish a real-world outcome.

Limitations and common mistakes

  • Equal mixture and probabilities strictly inside the unit interval. Finite floating-point calculation with the displayed domain; large integer counts can lose exact precision.
  • Use the displayed unit in every field. Ratios and percentages are different inputs; percent fields use values such as 25 rather than 0.25.
