Question
In deep learning, what is the purpose of a loss function?
To remove data for which no known label values are provided
To evaluate the aggregate difference between predicted and actual label values
To calculate the cost of training a neural network rather than a statistical model
Solution
The purpose of a loss function in deep learning is to evaluate the aggregate difference between predicted and actual label values.
Here's a step-by-step explanation:
-
In deep learning, a model is trained to make predictions on a dataset. These predictions are based on the input data and the current state of the model, which is determined by its parameters.
-
Each prediction made by the model is compared to the actual, known value. This comparison is done using a loss function, which calculates a single numerical value that represents the difference between the predicted and actual values.
-
The goal of training the model is to adjust its parameters in such a way that the value of the loss function is minimized. In other words, the model should make predictions that are as close as possible to the actual values.
