Well done. Semi-supervised learning is sometimes used in recommendation systems when only a small subset of user data is labelled, and a larger portion is unlabelled.
Correct, well done! Planning is the first step in the machine learning lifecycle. This phase involves understanding the problem, setting objectives and determining the data and resources needed for the project.
That's correct, great job! In supervised learning, the key feature is labelled data. Each input has a corresponding output label, allowing the model to learn from this input-output relationship and generalise to new data.
That's right. Well done. Reinforcement learning is a methodology where an agent learns to take actions in an environment based on feedback received in the form of rewards or penalties, improving its decision-making over time.
Great work! That's correct. Recommendation systems are designed to personalise the user experience, which helps increase customer engagement, retention and ultimately sales by recommending relevant products and services.
Awesome job! Data sparsity refers to the challenge of not having enough data on new users or products to make accurate recommendations.
Good job! John McCarthy is credited with coining the term 'artificial intelligence' in 1956, and he was instrumental in promoting symbolic reasoning as a core element of early AI research.
Great answer! Yes, machine learning is a subset of AI, which focuses on algorithms that improve with experience (data). AI encompasses a wider range of techniques for simulating human-like intelligence.
Way to go! Model evaluation and validation take place during the model development phase. In this phase, the model is trained, tested and validated to ensure it performs well.
You got this! Data preparation is the stage where raw data is collected, cleaned and transformed into a format suitable for training machine learning models.
Here is the updated code:
