Machine learning, a subset of artificial intelligence, also heavily relies on probability and statistics. Machine learning algorithms learn from past data and use that knowledge to make predictions or decisions. Probability is used to find the most likely outcome, while statistical models help in training and evaluating machine learning algorithms.
For example, in image recognition tasks, probability and statistics are used to classify images into different categories. The algorithm compares the features of the image with the probabilities of each category to determine the most likely classification. Statistical models are then used to optimize and improve the accuracy of the algorithm.
Network modeling is another area of computer science where probability and statistics come into play. Networks, such as social networks or computer networks, are complex systems with interconnected entities. Probability is used to model the behavior of these networks and predict outcomes.
For example, in network security, probability is used to analyze the likelihood of a cyber-attack happening and the potential impact it could have. By understanding the probabilities, computer scientists can develop strategies to protect the network and mitigate the risks.
