Hi Guys,
I am playing around MLP classifier lately. So i have about 450 inputs to
classify. Each input is a vector of array size 50. I am trying to fit the
model with 90% as train data.
Size of training data: (398, 50)
Size of testing data: (45, 50)
MLP instantiation:
gen_class =
MLPClassifier(hidden_layer_sizes=(200,),max_iter=3000,learning_rate='adaptive',alpha=0.025,warm_start=True)
Batch size is auto so it is taking 200 as batch_size. But when i am fitting
the classifier model, i am getting following error:
Traceback (most recent call last):
File "intent_detection_classifier_selection.py", line 452, in <module>

Thanks,
