Randomized trial evaluates tea grading accuracy via a novel deep learning model, suggesting improvements for quality control.

This research aims to develop a high-accuracy grading model for Chunmee tea using advanced deep learning techniques.
Improved DeepSpectra model was developed, integrating Inception module and residual connections for feature extraction.
360 samples of Chunmee tea were collected and preprocessed using multiplicative scatter correction.
Model performance was assessed through a 7:1:2 train-validation-test split with five-fold cross-validation.
The DeepSpectra model achieved an average test accuracy of 96.39 ± 1.63%.
It significantly outperformed alternative models with p < 0.05.
Demonstrated low inference latency of 2.2 ms, suitable for real-time applications.
