Learn about the Confusion Matrix with Real-Life Examples. A confusion matrix is a table that shows how well an AI model makes predictions. It compares the actual results with the predicted ones and tells which are right or wrong. It includes True Positive (TP), False Positive (FP), False Negative (FN), and True Negative (TN).

Firefly Optimization Algorithm

Firefly algorithm is a swarm-based metaheuristic algorithm that was introduced by Yang. Firefly Algorithm is inspired by the FLASHING Behavior of Fireflies. 

Assumptions

  • Fireflies are attracted to each other.
  • Attractiveness is proportional to BRIGHTNESS. 
  • Less Brighter Firefly is attracted to the Brighter Firefly.
  • Attractiveness decrease as the distance between 2 fireflies increase.
  • If brightness for both is the same, fireflies move randomly.
  • New Solutions are generated by Random walks & the Attraction of fireflies.

Firefly Optimization Algorithm Steps
  1. Initialize Parameters.
  2. Generate Population of n Fireflies.
  3. Calculate Fitness Value for Each Firefly.
  4. Check stopping criteria if (CurrentIteration := 1 to MaximumIteration ).
  5.  Update Position and Light Intensity for Each Firefly.
  6. Report the Best Solution.
Initialize Parameters, Population of Fire Fly Swarm.
Population Size (n) = 20;
Maximum Iteration (Maxt) = 50;
Dimension (d) = 10;
Upper Bound [UB] = 100;
Lower Bound [LB] = -100;

Calculate Fitness Value [Light Intensity] for Each FireFly.
The light intensity of Firefly (i.e., 𝐼_𝑖) at 𝑥_𝑖 is computed by the Value of the Objective Function.

Firefly Position Updated as:
For i = 1 to n -1;
For j = i + 1 to n;
  IF ( 𝑰_𝒋 > 𝑰_𝒊 )
      Update Position. [move Firefly i towards Firefly j ];
    End IF
  End For
 End For
