Latent Autoregression in GP-VAE Language Models: Ablation Study
Analysis
This paper investigates the impact of latent autoregression in GP-VAE language models. It's important because it provides insights into how the latent space structure affects the model's performance and long-range dependencies. The ablation study helps understand the contribution of latent autoregression compared to token-level autoregression and independent latent variables. This is valuable for understanding the design choices in language models and how they influence the representation of sequential data.
Key Takeaways
- •Latent autoregression in GP-VAE models improves long-range structure and stability.
- •Removing latent autoregression degrades latent structure and leads to unstable behavior.
- •The study highlights the role of latent autoregression in organizing long-range dependencies.
- •The findings are an empirical analysis of representational structure, not a new architectural proposal.
Reference
“Latent autoregression induces latent trajectories that are significantly more compatible with the Gaussian-process prior and exhibit greater long-horizon stability.”
