This dataset contains the test splits used to evaluate the Memory Decoder model across three specialized domains: biomedical, legal, and finance. The test data was randomly sampled from publicly available datasets to assess the model's performance in domain-specific language understanding.
GitHub: https://github.com/LUMIA-Group/MemoryDecoder
The test data is sampled randomly from the following source datasets:
The dataset consists of test splits only, randomly sampled from the source datasets:
βββ biomed/ # Biomedical domain test split
βββ law/ # Legal domain test split
βββ finance/ # Finance domain test split
