I need to identify the main categorical columns and find their most common values with frequencies. Let me start by examining the dataset structure. ```json { "action": "tool_call", "reasoning": "The dataset card shows many classifier columns. I'll inspect the raw.ae table to understand the categorical columns better, focusing on those with reasonable cardinality (not too many distinct values). From the card, columns like AESEV, AESER, AEOUT, AEREL, AEBODSYS, AESOC appear to be key categorical fields with manageable distinct counts.", "tool": "inspect_columns", "args": { "table": "raw.ae", "columns": ["AESEV", "AESER", "AEOUT", "AEREL", "AEBODSYS", "AESOC", "AELLT", "AEDECOD"] } } ```
