Comparison Card for Exact Match

Comparison description

Given two model predictions the exact match score is 1 if they are the exact same, and is 0 otherwise. The overall exact match score is the average.

  • Example 1: The exact match score if prediction 1.0 is [0, 1] is 0, given prediction 2 is [0, 1].
  • Example 2: The exact match score if prediction 0.0 is [0, 1] is 0, given prediction 2 is [1, 0].
  • Example 3: The exact match score if prediction 0.5 is [0, 1] is 0, given prediction 2 is [1, 1].

How to use

At minimum, this metric takes as input predictions and references:

>>> exact_match = evaluate.load("exact_match", module_type="comparison")
>>> results = exact_match.compute(predictions1=[0, 1, 1], predictions2=[1, 1, 1])
>>> print(results)
{'exact_match': 0.66}

Output values

Returns a float between 0.0 and 1.0 inclusive.

Examples

>>> exact_match = evaluate.load("exact_match", module_type="comparison")
>>> results = exact_match.compute(predictions1=[0, 0, 0], predictions2=[1, 1, 1])
>>> print(results)
{'exact_match': 1.0}
>>> exact_match = evaluate.load("exact_match", module_type="comparison")
>>> results = exact_match.compute(predictions1=[0, 1, 1], predictions2=[1, 1, 1])
>>> print(results)
{'exact_match': 0.66}
