Researchers have introduced VTBench, a novel framework designed to enhance time-series classification by integrating chart-based visualizations with raw numerical data. This multimodal approach generates interpretable plots like line, area, bar, and scatter charts to offer complementary views of signals. Experiments across 31 datasets indicate that chart-only models can be competitive, especially with smaller datasets, and combining multiple chart types can improve accuracy by capturing diverse visual cues. The framework also provides guidelines for selecting optimal chart types and fusion strategies for improved interpretability and effectiveness. AI
