Details

The PVT project implements a robust deep learning architecture centered around the Pyramid Vision Transformer (PVT) for diverse computer vision tasks. The system is structured into six key components: a Data Pipeline for efficient data preparation, a PVT Model Core providing the foundational feature extraction, and Task-Specific Heads that adapt the core features for classification, detection, or segmentation. The Training & Experiment Orchestrator manages the entire model lifecycle, from distributed training to checkpointing, while the Model Evaluation & Analysis component rigorously assesses performance. All operational parameters are centrally managed by the Configuration Manager, ensuring reproducibility and streamlined experimentation. This modular design promotes clear data flow and component interaction, making it suitable for scalable development and deployment.

Data Pipeline [Expand]

Manages the entire data lifecycle, from loading raw image datasets to applying necessary transformations (e.g., resizing, normalization, augmentation) and batching. It ensures data is efficiently prepared for model consumption across various tasks (classification, detection, segmentation).
