The exceptional efficiency of language fashions (LMs) means that large-scale next-word prediction may successfully distill data from textual content corpora into interactive brokers. LMs have achieved spectacular outcomes on numerous pure language processing benchmarks, surpassing state-of-the-art strategies and even outperforming people in duties requiring advanced reasoning. Nevertheless, it’s essential to find out whether or not their success stems from task-general reasoning expertise 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 research, the researchers examine the generalizability of LMs to new job variants by altering the situations or guidelines underneath which well-performing duties are carried out. The overall 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 embrace 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 job 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 somewhat than summary, generalizable reasoning expertise.
The findings additionally reveal thrilling relationships between mannequin conduct 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. General, slight variations within the default instantiations of duties current challenges for LMs, indicating that the success of current fashions shouldn’t be solely attributed to their basic capability for the goal job.
