[scikit-learn] Calculating prediction probability per each predicted outcome

Hi Suranga,

if you are using the MLPClassifier class, it should have a predict_proba() method.
predicted = neural_network.predict_proba(test_data)

Best regards,

Hi everyone,

I'm currently using Scikit learn to train and test multiple neural networks.

My issue - I'm breaking my dataset into 90/10, training on the 90%, and testing on the 10%.

For the 10% trained data, I get outcomes as follows:

predicted = neural_network.predict(test_data)

Here, the predicted variable is basically either 1 or 0, which is what i'm feeding in as the outcome.

But how can I get the prediction probability per each predicted outcome? back in the day when I used weka it produced a single prediction, followed by a prediction probability between 1 and 0 for each outcome.

Best Regards,
