# Metric Card for FBeta_Score

***Module Card Instructions:*** *Fill out the following subsections. Feel free to take a look at existing metric cards if you'd like examples.*

## Metric Description
*Compute the F-beta score.
The F-beta score is the weighted harmonic mean of precision and recall, reaching its optimal value at 1 and its worst value at 0.
The beta parameter determines the weight of recall in the combined score. beta < 1 lends more weight to precision, while beta > 1 favors recall (beta -> 0 considers only precision, beta -> +inf only recall).*

## How to Use
``` python

f_beta = evaluate.load("leslyarun/f_beta")
results = f_beta.compute(references=[0, 1], predictions=[0, 1], beta=0.5)
print(results)
{'f_beta_score': 1.0}   

```
