Keratoconus Severity Classification Using Features Selection and Machine Learning Algorithms
Input data: | i. Dataset D. | ii. A distance calculation function. | iii. A number K | To predict a new observation X, do: | 1. Calculate all distances of this observation with the other observations in the dataset D. | 2. Retain the K observations from the dataset close to X using the selected distance calculation function. | 3. Take the values of retained observations: | a. if regression: Calculate the average of retained observations values. | b. if classification: Calculate the mode of retained observations values. | 4. Return the value calculated in step 3 as a predicted value by K-NN for the observation X. |
