Large Concept Models: Language Modeling in a Sentence Representation Space [paper] [code]This paper introduces Large Concept Models (LCM) that process whole sentences at once (instead of tokens), like how humans naturally think in complete ideas rather than individual words. They used the encoder-decoder SONAR model as frozen components, with the LCM model in the middle. So, first, the LCM model receives the sentence embedding from the SONARs encoder. Then, LCM generates the new embedding, which will be passed to SONARs decoder for generation.The selected architecture for LCM was named Two-Tower, which consists of two components: contextualizer and denoiser, that are implemented using transformer layers. They experimented with different architectures, but Two-Tower proved to be more effective. This approach provides strong performance across languages Read the full blog for free on Medium.Join thousands of data leaders on the AI newsletter.
