The exceptional efficiency of language fashions (LMs) means that large-scale next-word prediction may successfully distill information from textual content corpora into interactive brokers. LMs have achieved spectacular outcomes on varied pure language processing benchmarks, surpassing state-of-the-art strategies and even outperforming people in duties requiring complicated reasoning. Nevertheless, it’s essential to find out whether or not their success stems from task-general reasoning abilities or from recognizing and recalling particular duties encountered throughout pre-training.
Prior analysis has primarily targeted on instance-level generalization, which information contamination points can complicate. On this examine, the researchers examine the generalizability of LMs to new process variants by altering the situations or guidelines below which well-performing duties are carried out. The final reasoning process for these duties stays unchanged, however the particular input-output mappings are modified. These new duties termed counterfactual duties, deviate from the default situations and measure the mannequin’s task-level generalizability.
The researchers suggest a collection of 11 counterfactual analysis duties spanning a number of classes and domains. These duties embody deductive reasoning, code era, drawing, and spatial reasoning. Whereas the reasoning process stays constant throughout the unique duties and their counterfactual variants, the input-output mappings differ. This analysis goals to evaluate the pliability of LMs in adapting to new process variations.
The efficiency of GPT-4, GPT-3.5, Claude, and PaLM-2 is evaluated on each the default and counterfactual situations of the duties. The outcomes point out that whereas LMs present above-random counterfactual efficiency, their efficiency persistently degrades in comparison with the default settings; this implies that the fashions’ success on these duties might be attributed partly to default-condition-specific behaviors quite than summary, generalizable reasoning abilities.
The findings additionally reveal thrilling relationships between mannequin habits on default and counterfactual duties. Correlations between default and counterfactual efficiency, the effectiveness of zero-shot chain-of-thought prompting, and interactions between task- and instance-level frequency results are noticed. Total, slight variations within the default instantiations of duties current challenges for LMs, indicating that the success of present fashions shouldn’t be solely attributed to their common capability for the goal process.
