Project Title: Machine Learning Based Error Detection in Transient Susceptibility Tests
#
Project Overview
This project aims to develop a sophisticated machine learning (ML) system for the automatic detection of errors in transient susceptibility tests used in electrical engineering applications. Transient susceptibility tests are critical for ensuring that electronic devices can withstand transient voltage conditions and operate reliably. Accurate error detection in these tests is essential for maintaining the quality and reliability of electronic devices, particularly as they become more complex and integrated.
#
Objectives
1. Data Acquisition: Collect a diverse dataset of transient susceptibility test results, including both successful tests and those with known errors.
2. Preprocessing: Implement data preprocessing techniques to clean and prepare the data, eliminating noise and normalizing input features.
3. Feature Engineering: Identify and extract relevant features from the time-domain signals obtained from the tests, which are indicative of possible errors.
4. Model Development: Develop machine learning models that can effectively classify test results as either ‘successful’ or ‘error-prone.’ This includes exploring various algorithms such as decision trees, support vector machines, and neural networks.
5. Model Training and Testing: Train the models on a portion of the data while validating their performance on a separate test set to ensure robustness and reliability.
6. Error Classification: Implement techniques to not only detect errors but also classify the types of errors based on their characteristics.
7. Evaluation Metrics: Evaluate model performance using metrics such as accuracy, precision, recall, and the F1 score to ensure the deployed model meets industry standards.
8. Integration and Deployment: Develop a user-friendly interface for engineers to use the machine learning model in real-time during testing, providing automated feedback on test results.
9. Continuous Learning: Establish a framework for the model to learn from new data over time, improving its accuracy and adapting to new testing conditions.
