  • What are prerequisites to start learning machine learning?

    Machine learning is a subset of artificial intelligence that involves the development of algorithms and statistical models that enable computers to learn from and make predictions or decisions based on data, without being explicitly programmed to perform a specific task. In essence, machine learning algorithms use patterns and inference to make sense of data and improve their performance over time.
