Researchers have developed SketchMamba, a novel lightweight state-space model designed for real-time sketch classification and stroke auto-completion. Unlike previous models that handle recognition and generation separately, SketchMamba processes a sketch as a single causal sequence, enabling it to classify drawings progressively as they are being made and simultaneously predict their continuation. Tested on a subset of the Quick, Draw! dataset, SketchMamba achieved 94.93% final-step accuracy and demonstrated a strong progressive-accuracy AUC of 0.706, reaching over 90% of its final accuracy with only 70% of the strokes drawn. The model's effectiveness is attributed to a dense per-step classification loss applied to its selective state-space backbone, outperforming Transformer, recurrent, and convolutional baselines in matched-budget comparisons.
