| Challenge: | Disinformation can cause disruption in the share market, panic and anxiety in society, and even death during crises. |
| Approach: | a new dataset is being developed to help combat disinformation . the dataset is a multimodal fake news dataset with 5W question-answering . |
| Outcome: | FACTIFY 3M is the largest dataset and benchmark for multimodal fact verification. |

| Challenge: | Recent studies have found that speech language models fail to capture brain-relevant semantics beyond low-level features. |
| Approach: | They analyze multimodal models to assess their alignment with MEG brain recordings . they find text embeddings from multimodal and unimodal models significantly outperform unilateral models . |
| Outcome: | a new study shows that text-based models outperform unimodal models in alignment with brain recordings during naturalistic story listening. |

| Challenge: | Existing benchmarks fail to test the full range of cognitive skills needed to process long-form videos . |
| Approach: | They propose a benchmark to evaluate models' ability to process long-form videos rigorously. |
| Outcome: | The benchmark measures the cognitive skills of models in understanding long-form videos . it offers the largest set of question-answer pairs for long video comprehension . |

| Challenge: | Training large foundation models for agentic tasks is impractical due to high computational costs, long iteration cycles, and rapid obsolescence as new models are released. |
| Approach: | They propose a method that trains a small LLM to generate supplemental text that helps the larger LLM solve the task more effectively. |
| Outcome: | The proposed approach decouples task-specific optimization from large foundation models . it achieves consistent and significant performance gains across diverse tasks and models - all without gradient access to the actor model. |

| Challenge: | Recent advances in Large Language Models (LLMs) have yielded impressive successes on many language tasks, but efficient processing of long contexts remains a significant challenge. |
| Approach: | They propose a method for processing long contexts in an episodic memory module while holistically attending to semantically-relevant context chunks. |
| Outcome: | The proposed method outperforms baseline decoders on multiple long-context recall and question-answering benchmarks on 16k to 256k tokens. |
