Xuehang Guo; Zhiyong Lu; Tom Hope; Qingyun Wang

Figure 6: Key Error Patterns. Through our case study on 120 samples, we identify seven key error patterns that correspond to the analysis challenges shown in Fig. 1 .

Figure 7: Preliminary Analysis On Failure Patterns. Analyzing on two different data types, table & figure , the agent shows its lack of accurate visual perception and its incapability of writing with proper analysis depth and width.

Figure 8: Preliminary Analysis On Failure Patterns. Analyzing on two data types with different data sources, formats, and domains, the agent generates analysis with significant hallucinated contents, meanwhile incapable of writing with proper analysis depth and width.

Figure 9: Scientific Analysis Workflow. Motivated by how human researchers perform scientific analysis, we decompose the scientific analysis workflow into dedicated stages, which leads to Anagent (Fig. 3 ).
