Neighbours, margins and rules retrieval

Supplied for this practice

These objects are prepared afresh before your editor runs.

query_id: Supplied query_id; its definition below specifies the values and role.
query_id = 117

Outputs you create

answer: The requested result, with the values, labels and row order described by this task.

Exercise evidence · ML-C-R2-1 · all 4 rows
`case_id`	`x`	`label`
117	2	A
81	1	A
96	3	B
63	4	B

Your task

Remove the query case from the supplied fitting table into answer before fitting or learning a scale.
Keep its row ID as the table index.

Hints

Think: Removing a self-match only from the displayed neighbour list would not repair the original fit. Fit preparation and the classifier on the separated fitting rows.

Tools: Neighbours, margins and rules retrieval: use the supplied case_id, x, label columns and the pandas or model operations introduced in this lesson.

Approach: Compute answer from the supplied evidence. Preserve the requested labels and row order, then inspect the values before checking.

Explained solution

answer = df.loc[df['case_id'] != query_id].set_index('case_id')
print(answer)

Removing a self-match only from the displayed neighbour list would not repair the original fit. Fit preparation and the classifier on the separated fitting rows.
