Cross-Regional Grapevine Cold Hardiness Prediction via Learned Multimodal Latent Representations

The paper introduces a new framework for predicting grapevine cold hardiness that learns transferable latent representations capturing region-specific variation. By inferring embeddings from cultivar descriptions, growing region text, and limited historical data, the method supports zero‑shot and few‑shot transfer to unseen regions. Experiments across six North American regions show that this approach outperforms existing models, delivering more accurate predictions and better performance in data‑scarce areas.

A Dataset-Centric Benchmark of Deep Learning Methods for Grape Leaf Disease Classification and Detection

The paper introduces a dataset‑centric benchmark for deep learning approaches to grape leaf disease classification and detection. It evaluates publicly available datasets on disease categories, annotations, acquisition conditions, and class distributions, and tests representative models across image‑level classification, region‑level classification, and object detection. Results reveal high accuracy on controlled datasets but significant performance drops on heterogeneous, real‑world data, especially in cross‑dataset transfer and object detection tasks.

PlantC2USeg: Cross-Scale Consistent Pre-Training for Few-Shot Unified Plant Point Cloud Segmentation

PlantC2USeg is a deep transfer‑learning framework that uses cross‑scale consistency learning and an information‑restricted decoder to improve plant point cloud segmentation. It achieves state‑of‑the‑art performance on Soybean3D and ShapeNet Part, and demonstrates strong few‑shot generalization across species and sensing conditions. The method reduces the need for large annotated datasets and lowers adaptation overhead for new plant species.

Multibranch Ensemble Head in Vision Foundation Models for Efficient Cucumber Phenological Stage Classification

The paper introduces a multibranch ensemble head that pairs low- and high-capacity branches for Vision Foundation Models, sampling one branch during training and averaging both at inference. This lightweight design adds negligible parameters and inference overhead while improving accuracy-efficiency trade-offs on data-scarce tasks. Applied to cucumber phenological stage classification, the DINOv2 ViT-S with the multibranch head achieves a Macro F1 of 0.978 and Cohen's Kappa of 0.971, matching larger models but with only 12.2 GFlops and 22.3 M parameters, enabling deployment on smartphones and edge devices.

GenoBERT: A Language Model for Accurate Genotype Imputation

GenoBERT is a transformer-based, reference‑free model that tokenizes phased genotypes and uses self‑attention to capture short‑ and long‑range linkage disequilibrium. Benchmarking on the Louisiana Osteoporosis Study and the 1000 Genomes Project shows GenoBERT outperforms four baseline methods, achieving an overall imputation accuracy of about 0.98 at up to 25% missing data and maintaining r² > 0.90 even at 50% missingness across multiple ancestries. The model’s 128‑SNP context window is sufficient to capture local correlation structures, and it remains robust to small sample sizes and weak LD, offering a scalable solution for genotype imputation without relying on reference panels.
