Calculating Output Probabilities from Model Scores
A model produces the raw output scores [2.0, 1.0, 0.1] for three possible classes. To convert these scores into a probability distribution, each score is exponentiated, and then each exponentiated score is divided by the sum of all the exponentiated scores. Calculate the resulting probability for each class. Show the main steps of your calculation and explain what the final probabilities indicate about the model's certainty.

Softmax Function Definition
A vector of raw, unnormalized scores
[1000, 1002, 999]is passed as input to a computational function that converts these scores into a probability distribution. A common technique to prevent numerical errors is to first subtract the maximum value of the vector from every element before applying the main transformation (exponentiation). Why is this subtraction step crucial for handling large input values?Calculating Output Probabilities from Model Scores
A model outputs the following raw, unnormalized scores for three classes:
[2.0, 1.0, 0.1]. If a constant value of 5.0 is added to each of these scores, resulting in a new score vector of[7.0, 6.0, 5.1], how will the resulting probability distribution calculated by the function that converts these scores to probabilities change?Order Preservation of the Softmax Function
