What is cost?
A measure of the resources or value spent to achieve a goal or complete a task
cost explained in plain English
Analogy
Think of cost like the price of a trip. Just as you need to consider the cost of gas, food, and lodging to plan a trip, AI systems need to consider the cost of computational resources, data, and time to complete a task.
Example
Self-driving cars use cost functions to optimize their routes and avoid obstacles, minimizing the cost of time, fuel, and safety risks.
How is cost used?
Cost is used in AI to optimize performance, make decisions, and allocate resources. For example, a machine learning model may be designed to minimize the cost of predicting a outcome, such as the cost of misclassifying a sample.
Common misconceptions about cost
Some people think that cost only refers to financial expenses, but in AI, it can also refer to other types of resources, such as computational power or data.
