Following the keras tutorial MLP classification here: https://keras.io/examples/nlp/multi_label_classification/.
I am able to successfully train a model and print out the top 3 predicted labels using the code below. I would also like to print out the prediction scores too. I can't seem to find how to do that in the documentation.
# Create a model for inference.
model_for_inference = keras.Sequential([text_vectorizer, shallow_mlp_model])
# Create a small dataset just for demoing inference.
inference_dataset = make_dataset(test_df.sample(100), is_train=False)
text_batch, label_batch = next(iter(inference_dataset))
predicted_probabilities = model_for_inference.predict(text_batch)
# Perform inference.
for i, text in enumerate(text_batch[:5]):
label = label_batch[i].numpy()[None, ...]
print(f"Abstract: {text}")
predicted_proba = [proba for proba in predicted_probabilities[i]]
top_3_labels = [
x
for _, x in sorted(
zip(predicted_probabilities[i], lookup.get_vocabulary()),
key=lambda pair: pair[0],
reverse=True,
)
][:3]
print(f"Predicted Label(s): ({', '.join([label for label in top_3_labels])})")
print(" ")
To access probabilities change this part:
top_3_labels = [
x
for _, x in sorted(
zip(predicted_probabilities[i], lookup.get_vocabulary()),
key=lambda pair: pair[0],
reverse=True,
)
][:3]
print(f"Predicted Label(s): ({', '.join([label for label in top_3_labels])})")
print(" ")
to this:
top_3_labels = [
(p, x)
for p, x in sorted(
zip(predicted_probabilities[i], lookup.get_vocabulary()),
key=lambda pair: pair[0],
reverse=True,
)
][:3]
print(f"Predicted Label(s): ({', '.join([l[1] for l in top_3_labels])})")
print(f"Predicted Probabilities(s): ({', '.join([l[0] for l in top_3_labels])})")
print(" ")
