From 7f2f0466d735424e886c1db88f76b7c5dd1716c1 Mon Sep 17 00:00:00 2001 From: ritesh313 Date: Wed, 4 Feb 2026 16:32:54 -0500 Subject: [PATCH 1/5] feat: add inference module with taxonomic level classification support MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Major addition: - Complete inference API for loading models and making predictions - Support for species-level (167 classes) and genus-level (60 classes) classification - TreeClassifier class with from_checkpoint() and predict() methods - Label mapping system with JSON metadata files - Image preprocessing pipeline for various input formats Core enhancements: - DataModule now supports taxonomic_level parameter ('species' or 'genus') - Genus extraction via species_name.split()[0] for 60-class classification - WeightedRandomSampler support for class balancing - External test set with species overlap filtering Documentation: - Comprehensive docs/taxonomic_levels.md guide (314 lines) - Label inspection script for validation - Test scripts for inference verification - Examples of progressive training (genus → species) Files added: - neon_tree_classification/inference/ (complete module) - docs/taxonomic_levels.md - scripts/create_label_mappings.py - scripts/test_inference.py - processing/misc/inspect_labels.py Modified: - neon_tree_classification/core/datamodule.py (+163 lines) - neon_tree_classification/core/dataset.py (+77 lines) - examples/train.py (+21 lines) - docs/training.md (+18 lines) This enables: 1. Quick model deployment with TreeClassifier.from_checkpoint() 2. Flexible training at species or genus level 3. Production-ready inference with batch prediction 4.
