| Challenge: | Large language models generate long chain of thoughts but memory footprint grows with output length . prior work on KV cache optimization focused on compressing long input context . |
| Approach: | They propose a new approach that compresses verbose reasoning thoughts into summaries . they use a dynamic KV cache selection policy that leverages these summary keys . |
| Outcome: | The proposed approach reduces memory usage while avoiding full-cache attention at each step. |
Chinese-Portuguese Machine Translation: A Study on Building Parallel Corpora from Comparable Texts (L18-1)
Copied to clipboard
| Challenge: | Chinese and Portuguese are very populous languages, but there is not much parallel corpora in the Chinese-Portuguese language pair. |
| Approach: | They propose to curate Chinese-Portuguese parallel corpora and evaluate their quality . they extract bilingual data from government websites and use Phrased-Based Machine Translation (PBMT) and Neural Machine Translation models to build large corpus. |
| Outcome: | The proposed method can be used as a benchmark for future Chinese-Portuguese MT systems. |

| Challenge: | Existing approaches to training agents for visual-language models trap them in local optima, hindering exploration and error correction with the environment. |
| Approach: | They propose a hierarchical training recipe that bridges atomic action execution and strategic task completion. |
| Outcome: | The proposed training recipe bridges atomic action execution and strategic task completion. |
