# Language Modeling on WikiText-2 10K-word evaluator standardized Source: [Language Modeling on WikiText-2 10K-word evaluator standardized]() Collection index: [llms.txt]() Data updated: 2026-05-18T09:28:33.783Z Evaluation of language modeling performance using the specific 10K-word evaluator standardized subset of the WikiText-2 dataset, measured by the change in Perplexity (PPL Delta). A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. | Scope | Recorded value | | --- | --- | | Task | Language Modeling | | Dataset (including any stated split) | WikiText-2 10K-word evaluator standardized | | Metric | PPL Delta (%) | | Unit | SCALAR | | Direction | Lower is better | | Results loaded | 18 of 18 | | Coverage | All results currently returned for this benchmark | Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol. ## Metrics - [PPL Delta (%)](): Lower is better; unit: SCALAR. ## Recorded results | Method | PPL Delta (%) | Result date | Report paper | | --- | --- | --- | --- | | BI-guided | 11.9 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | SLEB-one-shot | 13.6 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | SLEB-iterative | 13.6 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | Taylor importance | 13.6 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | CKA-guided | 18.1 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | SLEB-one-shot | 31.5 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | SLEB-iterative | 31.5 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | BI-guided | 33.2 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | CKA-guided | 50.9 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | Taylor importance | 56.3 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | Random | 74.1 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | BI-guided | 74.3 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | SLEB-iterative | 79.3 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | CKA-guided | 88 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | SLEB-one-shot | 116.5 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | Random | 152.8 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | Taylor importance | 199.2 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | | Random | 206.3 | Not recorded | 6a0a9d3adbc836b87d82b5e8 | ### BI-guided PPL Delta (%): 11.9.
