A big thank you to you ❤️❤️❤️... This tutorial is very very Really thanks alottt❤️
U have done a great job

[shibbirahmed]

thank you so much. Learned a lot. I have a few question. Please help me.
1. I am also getting 74% accuracy using SVM. which parameters can I use to increase accuracy of SVM ?
2. I am getting an error said" UndefinedMetricWarning: Precision and F-score are ill-defined and being set to 0.0 in labels with no predicted samples. Use `zero_division` parameter to control this behavior" while getting classification report using MultinomialNB Classifier. How can I solve this error???

[dinkan]

Is this done using naive bayes classification??

[kkamit]

Could you share some hypertuning and data cleaning tips for tweets Analysis

[NurulIstiqamahnoe]

Hello sir, I have a question, how to make label for the sentiment dataset which no have label before? Have there some tools or I have to labeling manually?

[ayencoscolfield]

please can you post video on sentiment analysis on suicidal classification using twitter data

[chithrakishore]

Thank you.
I got an error, ValueError: X has 9 features, but LinearSVC is expecting 10000 features as input. When I run
x= 'congratulations, you have done it'
vec = tfidf.fit_transform([x])
clf.predict(vec)

[mohithshivu]

Sir my name is mohith I am final year BE student can you help me out some doubt on nlp I am working on data generalization and data sanitization our task is identifying given text weather it is sanitized or not generalized or not how it work in python can you help out sir please.... it is helpfull to me

[carloslopez]

I think to make a prediction you also need to save tfidf object to transform word in vectors.
