Long Ans Questions

Q.1: Explain the five stages of the AI Project Cycle.
Ans: The AI Project Cycle consists of five stages:  

  1. Problem Scoping: Define the problem and set the project goal by analyzing parameters affecting the problem using tools like the 4Ws Problem Canvas.  
  2. Data Acquisition: Collect data that forms the base of the project, identifying data features relevant to the problem.  
  3. Data Exploration: Represent data graphically to identify trends and patterns, making it understandable for humans.  
  4. Modeling: Develop AI models using mathematical representations, either through rule-based or learning-based approaches, to analyze data and make predictions.  
  5. Evaluation: Test the trained model with testing data to calculate its efficiency using metrics like accuracy, precision, recall, and F1 score.

Q.2: Describe the 4Ws Problem Canvas and how each block contributes to problem scoping.
Ans: The 4Ws Problem Canvas helps identify key elements of a problem:  

  • Who: Identifies stakeholders affected by the problem and details about them, ensuring focus on those who will benefit from the solution.  
  • What: Determines the nature of the problem and gathers evidence (e.g., media or articles) to confirm its existence, clarifying the problem’s scope.  
  • Where: Analyzes the context, situation, and location where the problem is prominent, providing situational clarity for solution deployment.  
  • Why: Lists the benefits of solving the problem for stakeholders and society, justifying the need for a solution.
    These blocks collectively provide a structured approach to understanding and summarizing the problem for effective scoping.

Q.3: Discuss the difference between supervised and unsupervised learning models with examples.
Ans: Supervised learning uses labeled data to train models, where each data point is tagged with a label. For example, a dataset with images of apples and bananas labeled as such allows the model to predict whether a new image is an apple or banana. Unsupervised learning uses unlabeled data to identify patterns, such as clustering or dimensionality reduction. For instance, clustering can group unknown data based on patterns, while dimensionality reduction simplifies high-dimensional data like words in NLP. Supervised learning relies on predefined labels, while unsupervised learning discovers patterns independently.  

Q.4: Explain how neural networks work, including the roles of the input, hidden, and output layers.
Ans: Neural networks mimic human brain neurons to process data and solve tasks, especially with large datasets like images. They consist of:  

  • Input Layer: Acquires raw data and feeds it into the network without processing, acting as the entry point.  
  • Hidden Layers: Process the data using machine learning algorithms, with each node executing specific tasks and passing results to the next layer. Multiple hidden layers may exist depending on task complexity.  
  • Output Layer: Receives the final processed data from the last hidden layer and presents it to the user without further processing, serving as the user interface.
    Neural networks automatically extract features, making them efficient for complex tasks.

Q.5: Evaluate the importance of creating a virtual environment for Python projects and how it is done using Anaconda.
Ans: Virtual environments are critical for Python projects because they isolate project dependencies, preventing conflicts between projects with different requirements, such as different Python versions. This ensures that dependencies do not affect the base environment or other projects, maintaining stability and compatibility. Using Anaconda, a virtual environment is created as follows:  

  1. Open the Anaconda Prompt, which starts in the base environment.  
  2. Create a new environment with a specific Python version, e.g., conda create -n env python=3.7.  
  3. Confirm the installation by typing Y when prompted.  
  4. Activate the environment using conda activate env, changing the prompt to indicate the active environment.  
  5. Install Jupyter Notebook dependencies with conda install ipykernel nb_conda jupyter to enable Jupyter Notebook usage in the environment.
    This process ensures a clean, isolated workspace for AI project development, enhancing project organization and reliability.
