Linear regression

anchor

Fits a straight-line relationship between a predictor and an outcome. Used here to test whether a model's response varies systematically with a continuous quantity such as distance.

Findings

• IC-1553GPT-J, GPT-2-XL, and Llama-13B decode approximately 48% of tested relations via a linear transformation on the subject representation, and this structure causally influences predictions [compared-to]
• SY-002Sybil responds more weakly to nodules near the pleura, where adenocarcinoma tends to appear [primary]
