Researchers have developed ReconSpan, a novel method for adaptive latent tokenization that maps fine-grained text inputs to shorter sequences of continuous representations. This approach divides text into chunks, using a backward decoder to reconstruct them from a single contextual prefix code, which is then retained as the latent token for each chunk. The reconstruction criterion, applied during chunk formation, allows a single trained autoencoder to achieve average chunk lengths between 6.5 and 12.2, preserving more text than random boundaries at matched lengths. While readers can reliably extract topic information from the resulting latent sequences, they face challenges in recalling exact details. AI
IMPACT This method could lead to more efficient processing of text data in AI models by reducing sequence length while preserving topic information.
