Researchers have developed CANDLE, a novel system for character-level Arabic noise deduplication. This system utilizes Connectionist Temporal Classification (CTC) to frame normalization as a sequence alignment problem, a method not previously applied to character deduplication. Evaluated on various benchmarks, CANDLE achieved a Sentence Error Rate as low as 5.37% and significantly outperformed a classification-based baseline. The system was further distilled into a smaller, 2-layer model with minimal performance loss, offering practical benefits such as a reduction in tokenizer fertility for Arabic LLMs, thereby lowering inference costs and improving context window utilization.
