Python for Artificial Intelligence: Introduction to Machine Learning
Machine learning is a branch of artificial intelligence (AI) focused on creating algorithms that learn from data and make predictions or decisions without explicit programming. Here’s a simple breakdown of how machine learning works:
- Data Collection: Machine learning algorithms need data to learn patterns. This data can be in structured, semi-structured, or unstructured formats.
- Data Preprocessing: Raw data often needs to be cleaned, transformed, and prepared before it can be used to train machine learning models.
- Model Training: Models learn patterns and relationships from labeled training data. They adjust internal parameters based on input data to minimize errors between predicted and actual values.
- Model Deployment and Monitoring: Trained models can be deployed to make predictions on new data. It’s important to monitor and periodically retrain the model with new data to maintain its accuracy.
By following these steps, machine learning enables computers to learn and improve their performance on specific tasks over time.
