## How do you reduce expected loss?

For a given input vector x, our uncertainty in the correct class is expressed through the joint probability distribution p(x, Ck). to eliminate the common factor p(x). Therefore, the decision rule that minimizes the expected loss is one that assigns x to the class for which the quantity: is minimum.

## Why do we calculate expected loss?

The loss given default (LGD) is an important calculation for financial institutions projecting out their expected losses due to borrowers defaulting on loans. The expected loss of a given loan is calculated as the LGD multiplied by both the probability of default and the exposure at default.

## Which increases the frequency of loss?

Hazard: Condition that increases the probability of loss.

## What is an example of loss control?

This includes risks from fire and crime to chemical spills, slips and falls, auto accidents, cyber threats, and legal issues. Loss controls include proactive measures like policies, procedures, training, and tools that help reduce the frequency and severity of losses.

## What is the difference between loss prevention and loss control?

Loss control (a.k.a. risk reduction) can either be effected through loss prevention, by reducing the probability of risk, or loss reduction, by minimizing the loss.

## What is expected loss in machine learning?
