Loss Function
A loss function is a specific type of objective function where the convention is that lower values indicate better model performance. Optimization algorithms actively seek to minimize the loss function to improve the model; any objective where higher is better can be converted into a loss function by simply flipping its sign.

Logistic Regression Cost Function
A machine learning model is being trained for a prediction task. A key metric, the objective function, is tracked over time. The value of this function represents the magnitude of the model's error. A graph of this process shows the objective function's value consistently decreasing as the number of training iterations increases. What is the most accurate interpretation of this trend?
