Researchers have introduced Lapras, a novel post-training framework designed to enhance the reasoning capabilities of Time Series Language Models (TSLMs). This framework enables TSLMs to perform latent reasoning within the joint time series-language space, generating text only for the final answer. Lapras achieves this through a teacher-student self-distillation process, where a student model aligns its internal states with a teacher model trained on explicit Chain-of-Thought (CoT) traces. Evaluations on multiple benchmarks show that Lapras significantly improves performance, reducing token generation by over 23 times while maintaining interpretability through decodable reasoning traces.
