Chapter 1: AI Project Cycle Class 8

1.1 Introduction to AI Project Cycle

Artificial Intelligence (AI) aims to build systems that can think, learn, and make decisions like humans.
But how do we actually develop an AI solution?

To make this process structured and efficient, AI experts follow a step-by-step process called the AI Project Cycle.

It is similar to how we plan a school project — from identifying the problem, gathering information, designing the solution, testing it, and then presenting it.


💡 Definition:

The AI Project Cycle is a systematic process that guides the development of an AI solution — from understanding the problem to deploying the final model.


🔄 Why AI Project Cycle is Important

PurposeDescription
StructureIt organizes AI project development in clear steps.
AccuracyEnsures that the problem is correctly defined and solved.
EfficiencySaves time and resources.
EvaluationHelps in measuring the performance of AI models.

🧠 Analogy Example:

Think of it like preparing for your science exhibition project:

  1. Decide your topic → Problem Scoping
  2. Collect information → Data Acquisition
  3. Analyze what you found → Data Exploration
  4. Build your model/project → Modelling
  5. Test your project → Evaluation
  6. Present it in the exhibition → Deployment

1.2 AI Project Cycle — A Brief Discussion

The AI Project Cycle usually consists of 5 major stages, and sometimes a 6th stage (Deployment) is added.

StageNamePurpose
1Problem ScopingUnderstanding and defining the problem clearly.
2Data AcquisitionCollecting relevant data to solve the problem.
3Data ExplorationAnalysing and understanding data patterns.
4ModellingBuilding and training AI models using data.
5EvaluationTesting model accuracy and performance.
6Deployment(Optional) Making the model available for use.

1.3 AI Project Cycle — A Detailed Approach

Let’s study each stage in detail 👇


1.3.1 Understanding Problem Scoping

💡 Definition:

Problem Scoping means clearly identifying what problem you want your AI system to solve.


📋 Steps in Problem Scoping:

StepDescriptionExample
1Identify the ProblemTraffic jams in the city.
2Understand the NeedPeople face delays and pollution.
3Define the GoalPredict traffic and suggest alternate routes.
4Set the Success CriteriaAccuracy of traffic prediction model.

🧠 Mind Map: Problem Scoping

Problem Scoping
   |
   |-- Identify Problem
   |-- Understand Need
   |-- Define Goal
   |-- Set Success Criteria
   |-- Identify Stakeholders

🧩 Stakeholders:

People or groups who are affected by or interested in the project (e.g., drivers, police, government).


1.3.2 Data Acquisition

💡 Definition:

The process of collecting relevant and accurate data that helps the AI system learn.


📦 Sources of Data:

Source TypeExample
Primary DataSurveys, sensors, cameras, experiments
Secondary DataWebsites, databases, research papers

⚙️ Data Collection Tools:

  • Online forms and surveys
  • Web scraping tools
  • IoT sensors
  • Open-source datasets (like Kaggle, UCI ML Repository)

⚠️ Important:

Data must be reliable, relevant, and unbiased.
Bad data = Bad AI model.


1.3.3 Data Exploration

💡 Definition:

Data Exploration involves analyzing and visualizing data to find patterns, errors, or relationships.


📊 Activities in Data Exploration:

StepDescription
Data CleaningRemoving missing or incorrect values.
Data VisualizationUsing graphs, charts to understand data trends.
Feature IdentificationFinding which variables affect the outcome.

🧠 Example:

If you’re building an AI to predict student grades,
you might explore data like attendance, test scores, and homework completion.


📈 Common Tools:

  • Python (Pandas, Matplotlib)
  • Excel
  • Google Sheets
  • Tableau

1.3.4 Modelling

💡 Definition:

Modelling is the stage where you train the AI model using data to make predictions or decisions.


⚙️ Steps in Modelling:

StepDescription
Data SplittingDivide data into training and testing sets.
Model SelectionChoose algorithm (e.g., Decision Tree, Neural Network).
Model TrainingFeed data to model to learn patterns.
Model TestingCheck how well it performs on new data.

🧠 Example:

If you feed your AI model data of 1000 students’ grades,
it learns from 800 (training data) and predicts for 200 (testing data).


💬 Types of Models:

TypeExamplePurpose
ClassificationSpam or Not SpamCategorical prediction
RegressionHouse Price PredictionContinuous value prediction

1.3.5 Evaluation

💡 Definition:

Evaluation means testing and measuring the performance of the AI model.


📏 Common Evaluation Metrics:

MetricDescription
AccuracyHow often the model gives the right result.
PrecisionCorrectness of positive predictions.
RecallAbility to find all positive cases.
F1 ScoreBalance between precision and recall.

🧠 Example:

If your traffic prediction model correctly predicts 90 out of 100 traffic jams,
its accuracy = 90%.


⚠️ Note:

If performance is poor → go back, improve data or model.


1.3.6 Deployment — The 6th Stage of AI Project Cycle

💡 Definition:

Deployment means putting the AI model into real-world use so people can access its results.


🧰 Deployment Examples:

AI SystemDeployment Example
ChatbotAvailable on a website for customer queries
Face RecognitionUsed in security systems
Weather PredictionShown in mobile apps or websites

🧩 Post-Deployment Activities:

  • Monitoring performance
  • Collecting feedback
  • Updating the model with new data
