| contents | This study aims to understand how statistical biases affect the model's ability to generalize to in-distribution and out-of-distribution data on algorithmic tasks. Prior research indicates that transformers may inadvertently learn to rely on these spurious correlations, leading to an overestimation of their generalization capabilities. To investigate this, we evaluate transformer models on several synthetic algorithmic tasks, systematically introducing and varying the presence of these biases. We also analyze how different components of the transformer models impact their generalization. Our findings suggest that statistical biases impair the model's performance on out-of-distribution data, providing a overestimation of its generalization capabilities. The models rely heavily on these spurious correlations for inference, as indicated by their performance on tasks including such biases. |
