Apply SVM on LDA in python
Following your code in your other thread:

# Use tf (raw term count) features for LDA.
print("Extracting tf features for LDA...")
tf_vectorizer = CountVectorizer(max_df=0.95, min_df=2,
                                max_features=n_features,
                                stop_words='english')
t0 = time()
tf = tf_vectorizer.fit_transform(data_samples)
print("done in %0.3fs." % (time() - t0))

print("Topic modelling with LDA...")
lda = LatentDirichletAllocation(n_topics=n_topics, max_iter=5,
                                learning_method='online',
                                learning_offset=50.,
                                random_state=0)

lda_x = lda.fit_transform(tf)
# so lda_x is your doc-topic distribution that you can use for feature vector to your SVM model.
# lda.components_ is your topic-word distribution.


Hope this helps!
