Questions and answers designated by tag: Data Labeling

Given that I want to train a model to recognize plastic types correctly, 1. What should be the correct model? 2. How should the data be labeled? 3. How do I ensure the data collected represents a real-world scenario of dirty samples?

Monday, 23 March 2026 by Reuben Amedalor

To address the problem of training a machine learning model for the recognition of plastic types, especially within the context of real-world scenarios where samples may be dirty or contaminated, it is necessary to approach the problem with a comprehensive understanding of the requirements and constraints associated with both data and model choice. The process
