Applied Sciences, Vol. 16, Pages 9098: Pairwise Classification as a Unified Framework for Offline Reinforcement Learning and Large-Language-Model Alignment

13+ hour, 10+ min ago   (496+ words) Offline reinforcement learning (offline RL) and large-language-model (LLM) alignment are typically studied as independent domains and each has developed its own pairwise comparison technique. Prior studies have validated pairwise classification exclusively within offline RL, leaving open the question of whether it…...

Applied Sciences, Vol. 16, Pages 8993: CDTS2: Causal Downstreamer with Causally Disentangled Trend and Seasonality Time-Series Representations

4+ day, 5+ hour ago   (411+ words) Time-series representation learning decomposes signals into interpretable factors such as trend and seasonality, and disentangled representation learning assigns these factors to distinct latent dimensions, enhancing interpretability and forecasting accuracy. However, existing methods achieve only statistical disentanglement: an intervention on one…...
