Entropy Calculator
Calculate the Shannon entropy of a probability distribution with clarity.
About Entropy Calculator
Welcome to our Entropy Calculator, a user-friendly tool designed to calculate the Shannon entropy of a discrete probability distribution. Entropy measures the unpredictability or average information content within a set of outcomes.
Features of the Entropy Calculator
- Step-by-Step Solutions: View a breakdown of how entropy is calculated.
- Visual Explanation: Two charts help illustrate both the probability distribution and each term of the entropy sum.
- Educational Clarity: Understand the role each outcome plays in total entropy.
- Easy Input: Enter probabilities in a comma-separated list.
- Accurate Computation: Combines symbolic and numeric methods for reliable results.
Understanding Entropy
For a discrete random variable \( X \) with possible outcomes \( x_i \) and corresponding probabilities \( p_i \), the Shannon entropy is given by:
\[ H(X) = - \sum_{i} p_i \log\bigl(p_i\bigr) \]This measures the average level of “surprise” or uncertainty in the distribution.
How to Use the Entropy Calculator
- Enter probabilities in a comma-separated list (e.g., 0.2, 0.3, 0.5).
- Confirm the probabilities sum to 1.
- Click on "Compute Entropy" for a step-by-step solution and charts.
Applications of the Entropy Calculator
- Information Theory: Understand core concepts of randomness and data encoding.
- Data Science & Statistics: Measure uncertainty or diversity in various data sets.
- Educational Use: Teach or learn the fundamentals of entropy calculation.
Why Use Our Entropy Calculator?
- Time-Saving: Rapidly compute entropy without manual summations.
- Intuitive: Clearly see how each probability contributes to the final entropy.
- Visual Learning: Two charts offer a direct sense of the distribution and its entropy terms.
