The model’s verdict

The Transformer retrained from the notebook (the 2024 weights were never saved), shown three ways. The first is how the notebook evaluated it.

Notebook protocol

Dev claims predicted in batches of 16, in file order, from the 2024 retrieved evidence, as the notebook does.

Retrieved vs gold evidence

Gold passages were picked by the dataset’s annotators. Retrieved passages are what the TF-IDF rule returned from all 1.19M passages. Switch between the submitted 2024 output and the re-runs.

2024 submission

The passages the team actually retrieved and submitted in 2024 (their saved output file). The file records only passage ids, so scores are recomputed with the submission rule.

    The essay stated the analysis was to test the hypothesis that the drafting of reports and statements by societies such as the Intergovernmental Panel on Climate Change, American Association for the Advancement of Science and National Academy of Sciences might downplay legitimate dissenting opinions on anthropogenic climate change.

    As the Earth's climate warms, we are seeing many changes: stronger, more destructive hurricanes; heavier rainfall; more disastrous flooding; more areas of the world experiencing severe drought; and more heat waves."

    This could lead to changing, and for all emissions scenarios more unpredictable, weather patterns around the world, less frost days, more extreme events (droughts and storm or flood disasters), and warmer sea temperatures and melting glaciers causing sea levels to rise.
