Study Notes
AI Project Cycle
- The AI Project Cycle is a step-by-step process to derive value from an AI project and solve problems.
- The cycle has five stages: Problem Scoping, Data Acquisition, Data Preprocessing, Model Training, and Model Evaluation and Deployment.
Problem Scoping
- Problem scoping is defining the project's goal and identifying the problem's different aspects.
- The '4Ws' help identify and understand the problem: Who, What, Where, and Why.
- Who identifies the stakeholders directly and indirectly affected by the problem.
- What analyzes the problem's nature, gathering evidence to confirm its existence.
- Where identifies the situation and where the problem arises.
- Why explains the need to address the problem and the advantages for stakeholders after solving it.
- The problem statement template summarizes the key points gathered from the '4Ws'.
Data Acquisition
- Data acquisition involves collecting accurate and reliable data for analysis.
- Data can be structured, unstructured, or both.
- Structured data is organized in a standardized format, easily accessible by humans and programs. It includes numbers, characters, and special characters.
- Unstructured data doesn't follow traditional data models, making it difficult to store and manage. Examples include videos, audio, images, and log files.
- Dataset is a collection of data in tabular format related to a specific subject.
- Datasets are divided into training and test datasets.
- Training dataset (usually 80%) teaches a machine learning model to make judgments or perform tasks.
- Test dataset (usually 20%) is used to evaluate the model's performance on unseen data.
Acquiring Data from Reliable Sources
- Surveys gather data through questionnaires from a predetermined sample to gain insights.
- Cameras collect visual data (unstructured) that can be analyzed by machine learning.
- Web Scripting collects structured data from the internet, such as market research or price tracking.
- Observation provides data through attentive monitoring and noticing patterns.
- Sensors collect data about physical properties using devices like biometrics.
- Application Program Interface (API) allows two applications to communicate and exchange data.
System Map
- A System Map visually represents the relationships between components within a system.
- The map depicts cause and effect relationships using arrows to connect elements.
- An example is the Water Cycle System Map, where all constituents are circled, and arrows show their interactions.
Studying That Suits You
