The text discusses the importance of selecting high-quality data examples for training classifiers using Large Language Models (LLMs), particularly in scenarios where only a few labeled examples are available, known as few-shot classification. It highlights that simple, consistent, and clear data examples lead to better model performance, while complex or nuanced examples can hinder effectiveness. The piece examines datasets like the Stanford Sentiment Treebank v2 (SST2) and Surge AI’s Toxicity Dataset, demonstrating how varying the training data can significantly impact model accuracy, with performance differences of up to 32% observed. It provides insights into what constitutes good and bad examples for few-shot learning, emphasizing the role of straightforwardness and consistency, while advising against the use of idiomatic expressions, negations, and overly similar class structures. The article underscores the critical role of data selection in enhancing model capabilities and encourages experimentation within a classification playground to apply these findings.
