1. Problem Identification: Define the problem AI will solve.
2. Data Collection: Gather relevant data from various sources.
3. Data Preparation: Clean, preprocess, and transform data for model training.
4. Model Selection: Choose the right AI/ML model based on problem type.
5. Model Training & Testing: Train the model on data and test its performance.
6. Evaluation: Measure accuracy using metrics like precision, recall, and F1-score.
7. Deployment: Integrate the model into an application for real-world use.
Q2. Why is data important in AI projects?
Answer : AI models learn patterns from data to make predictions. If the data is incomplete or biased, the model will be inaccurate.
Example: A self-driving car needs high-quality road and traffic data to function safely.
Q3. What is the role of machine learning in AI projects?
Answer : Machine Learning (ML) is a core component of AI that allows models to improve over time. It identifies patterns from historical data and applies them to new inputs.
Example: A spam filter in emails uses ML to classify messages as spam or not.

in speech, then infer meaning and provide a useful response.
➢ Fraud and Risk Detection by Banks and Finance companies through
customer profiling, past expenditures, and other essential variables to
analyse the probabilities of risk and default.
➢ Medical Imaging helps to understand patient’s health condition and
diseases.
Machine Learning (ML):
