| Challenge: | Existing methods for learning target side syntactic structure are greedy and only allow them to explore a limited portion of the latent space. |
| Approach: | They propose a new latent variable model, LaSyn, that captures the co-dependence between syntax and semantics while allowing for effective inference over the latent space. |
| Outcome: | The proposed model captures the co-dependence between syntax and semantics while allowing for efficient inference over the latent space. |

| Challenge: | APEX optimizes for text-to-image generation by combining learning potential, conflict penalty, and progress need. |
| Approach: | They propose an algorithm that stabilizes heterogeneous rewards and dynamically schedules objectives . they propose a method that achieves better Pareto trade-offs across four heterogenous objectives based on P3 Adaptive Priorities . |
| Outcome: | The proposed algorithm achieves better pareto trade-offs across four heterogeneous objectives while maintaining competitive OCR accuracy. |
