Initialize weights in sklearn.neural_network

I want to initialize weights in a MLPclassifier, but when i use sample_weight in .fit()
method,
it says that TypeError: fit() got an unexpected keyword argument 'sample_weight'
import sklearn.neural_network as SKNN
mlp_classifier = SKNN.MLPClassifier((10,), learning_rate="invscaling",solver="lbfgs")
fit_model = mlp_classifier.fit(train_data,train_target, sample_weight = weight)
i also read What does `sample_weight` do to the way a `DecisionTreeClassifier` works in sklearn?, it said that you should use sample_weight in the .fit()
method.
is there any way to use sample_weight
for MLPclassifier
like the one used in Decisiontreeclassifier
?

That is because MLPClassifier
unlike DecisionTreeClassifier
doesn't have a fit()
method with a sample_weight
parameter.
See the documentation.
Maybe some of the answers to this similar question can help:
How to set initial weights in MLPClassifier?
is there any way to use something likesample_weight
forMLPclassifier
like the one used inDecisiontreeclassifier

I don't think so - not unless one of the suggested work-arounds in the link I gave works. You might consider using Keras instead, as shown here: towardsdatascience.com/….

Also, you might be able to get something useful out of this conversation about adding a pre-training functionality from scikit's Github page: github.com/scikit-learn/scikit-learn/pull/3281

There are no sample weights in sklearn NN yet. But you can as the start:
- find it in Keras: https://keras.io/models/sequential/
- write the NN in numpy and implement sample_weight by yourself
