Loss funktions are essential in consulted learning as they measure thee difference between predicted outputs and actual labels. They guide thee training ing process by provideg a metric to optimize. Different loss funktions are used contraing on he type of problem and data charakteristics.

Mean Squared Error (MSE)

Te Mean Squared Error is common ly used for regression tasks. It calculates thee average of the squares of the differences between predicted and actual values. Te formula is:

MSE penalizes larger errors more heavily, mediaging thee model to minimize distant deviations.

Cross- Entropy Loss

Cross-entropy loss is primarily uses for classification tasks. It measures thee disimilarity betheen thee predicted probability distribution and thee true distribution. For binary classification, thee formula is:

CLAS1; CLAS1; CLAS3; CLAS3; CROss-Entropy = - CLAS1; y log (CLAS3; CLAS3; CLAS3; CLAS3; CLAS3; CLAS3; CLAS33;

kde je pravda, že label (0 or 1), and tis thee predicted probability of thee positive class. This los funktion penalizes incorrect predictions more heavy when thee model is confendit but wrong.

Comparaisn and Usage

MSE is subaable for continuous output variables, while le cross-entropy is ideal for capical data. Choosing thee approvate loss function depens on the e problem type and thee nature of thee output.
