Few-Shot Learning: Unlocking AI’s Potential in Data-Scarce Worlds
Latest 69 papers on few-shot learning: Aug. 25, 2025
In the rapidly evolving landscape of AI and Machine Learning, the quest for models that can learn effectively from minimal data is more critical than ever. This challenge, known as Few-Shot Learning (FSL), is the cornerstone for building adaptable and efficient AI systems, especially in domains where labeled data is scarce or expensive to acquire. Recent breakthroughs, as highlighted by a collection of compelling research papers, are pushing the boundaries of what’s possible, enabling AI to generalize from a handful of examples and tackle complex real-world problems.
The Big Idea(s) & Core Innovations
The overarching theme uniting recent FSL advancements is the ingenious use of pre-trained models, meta-learning, and novel architectural designs to bridge the gap between abundant general knowledge and sparse domain-specific insights. Researchers are moving beyond brute-force data collection, focusing instead on how models learn and transfer knowledge.
One significant innovation comes from the integration of Large Language Models (LLMs) and Vision-Language Models (VLMs) into FSL pipelines. For instance, the University of Virginia team in their paper, “Instruction-based Time Series Editing”, introduces InstructTime, allowing users to modify time series data using natural language instructions. Similarly, “Integrating Time Series into LLMs via Multi-layer Steerable Embedding Fusion for Enhanced Forecasting” by Zhuomin Chen et al. from Sun Yat-Sen University introduces MSEF, enabling LLMs to directly access and retain complex time series patterns across all layers, leading to a remarkable 31.8% reduction in Mean Squared Error (MSE) in forecasting tasks. This is further echoed by East China Normal University and Aalborg University’s “CC-Time: Cross-Model and Cross-Modality Time Series Forecasting”, which fuses PLMs with time-series-specific models for superior accuracy in few-shot scenarios by leveraging textual descriptions.
In computer vision, where data scarcity is a perennial issue, several papers present groundbreaking solutions. Cornell University and Weill Cornell Medicine’s “CoFi: A Fast Coarse-to-Fine Few-Shot Pipeline for Glomerular Basement Membrane Segmentation” leverages lightweight models and automated prompt generation using SAM (Segment Anything Model) for efficient and accurate medical image segmentation with limited data. Addressing fine-grained classification, New York University and Vanderbilt University’s “Glo-VLMs: Leveraging Vision-Language Models for Fine-Grained Diseased Glomerulus Classification” demonstrates that fine-tuning large VLMs can achieve high accuracy with as few as 8 shots per class, especially with pathology-aware backbones.
Meta-learning approaches are also seeing significant innovation. “Overcoming classic challenges for artificial neural networks by providing incentives and practice” by Kazuki Irie and Brenden M. Lake from Harvard and Princeton Universities introduces the Problem of Incentive and Practice (PIP) framework, utilizing metalearning to tackle systematic generalization, catastrophic forgetting, and FSL. This framework also underpins the robustness of LLMs. For a more generalized approach, Usman Anjum et al. from Ottawa University and University of Cincinnati introduce “Domain-Generalization to Improve Learning in Meta-Learning Algorithms” (DGS-MAML), which combines gradient matching with sharpness-aware minimization to boost generalization and convergence in FSL.
Robotics is another area benefiting immensely. Google Research and MIT CSAIL’s “In-Context Iterative Policy Improvement for Dynamic Manipulation” shows how pre-trained LLMs can iteratively improve robotic policies without fine-tuning, outperforming Bayesian Optimization in low-data regimes. Similarly, Tsinghua University’s “H-RDT: Human Manipulation Enhanced Bimanual Robotic Manipulation” uses human manipulation data and a diffusion transformer to achieve substantial improvements in robotic tasks, particularly in few-shot settings.

Impact & The Road Ahead
These advancements in few-shot learning are poised to democratize AI development, making advanced capabilities accessible even in data-scarce sectors like healthcare, robotics, and environmental monitoring. The ability of models to learn from minimal examples means faster deployment, reduced annotation costs, and more robust systems that can adapt quickly to changing environments or new tasks.
The trend of leveraging pre-trained large models (LLMs, VLMs) and meta-learning for rapid adaptation is particularly exciting. This paradigm shift suggests that future AI systems will be less about training monolithic models from scratch and more about intelligently transferring and fine-tuning existing knowledge. Key challenges remain, such as ensuring generalization robustness across extreme domain shifts (as explored in “Multiple Stochastic Prompt Tuning for Few-shot Adaptation under Extreme Domain Shift” and “Cross-Domain Few-Shot Learning with Coalescent Projections and Latent Space Reservation”), improving model interpretability (“Closed-Form Feedback-Free Learning with Forward Projection”), and safeguarding against vulnerabilities like tool poisoning attacks (“MCPTox: A Benchmark for Tool Poisoning Attack on Real-World MCP Servers”).
