FAQs 

1. What is the difference between machine learning and deep learning?
Machine learning focuses on algorithms that learn patterns from data to make predictions or decisions. Deep learning is a subset of machine learning that uses neural networks with multiple layers to process more complex patterns, usually in large datasets.

2. Do I need to know programming to work with machine learning?
Basic programming skills are essential for most machine learning tasks. Python is the most common language due to its ease of use and extensive ML libraries. Some platforms offer low-code or no-code solutions, but deeper customizations require coding knowledge.

3. How important is data quality in machine learning projects?
Data quality is critical because models learn patterns directly from the data they are trained on. Poor-quality data can lead to inaccurate predictions and unreliable results.

4. Can machine learning models work in real time?
Yes, with the right setup, models can process and respond to data in real time. This is common in applications like fraud detection and recommendation systems.

5. What hardware is best for training machine learning models?
The choice depends on the complexity of the model and dataset size. CPUs work for smaller models. On the other side, GPUs or TPUs are preferred for deep learning tasks due to faster processing.
