5.4 Error Analysis

We look into GPT-4V prediction traces and attempt to categorize common types of errors that cause mismatching between GPT-4V predictions and human annotations.

We notice false negative cases where the mismatches are rooted in inaccurate Set-ofMark (Yang et al., 2023b) annotation parsing or imperfect dataset annotation. In these cases, the predictions made by GPT-4V are correct after manual justification, but are classified as wrong predictions in automatic evaluation because the target regions are over-segmented (e.g., Figure 5(a)(b)), or because the ground-truth annotation only covers one of the many valid actions (e.g., Figure 6(a) has two Google Play logo; Figure 6(b) has multiple ways of accessing Google Search; and users may lookup “Setting” by direct search as GPT-4V, or by scrolling down as the human annotation in Figure 6(c)).

Figure 7 shows a few true negative examples of GPT-4V failing the designated tasks. In our zeroshot testing setup, GPT-4V is not provided with demonstrative examples to learn user action patterns. In this case, while users may scroll down or up to explore the GUI, we notice GPT-4V is more likely to perform the action of “click” on each screen, leading it to occasionally make short sighted decisions. In Figure 7(a), GPT-4V attempts to look for “improve location accuracy” in “Network&Internet” among the listed visible tabs, while the user decides to scroll down and look for more aligned setting tabs. In Figure 7(b), GPT-4V clicks on “Accept All”, which is not a button. In Figure 7(c), GPT-4V also shows a more literal understanding of the instruction and the current observation as in (b), clicking the “News” tab in the Google Search platform instead of actually visiting the news website.
