Diffusion models face a fundamental trade-off between generation quality and computational efficiency. Latent Diffusion Models (LDMs) offer an efficient solution but suffer from potential information loss and non-end-to-end training. In contrast, existing pixel space models bypass VAEs but are compu
Regional prompting, or compositional generation, which enables fine-grained spatial control, has gained increasing attention for its practicality in real-world applications. However, previous methods either introduce additional trainable modules, thus only applicable to specific models, or manipulat…
Long-term series forecasting is crucial in real-world applications. Existing works have leveraged self-attention mechanisms and multi-scale temporal data to learn complex dependencies and patterns in long-term series prediction. However, most prediction models directly aggregate together multi-scale…
Recent studies have shown that reinforcement learning (RL) methods have brought significant performance gains for stock portfolio management (PM) because they effectively utilize historical price information and directly generate portfolio weights. We found, however, that there is still great room f…
