NLP and PySpark Project using TF_IDF, Tokenizer and some NLP package Project is to create a Spam filter using NaiveBayes classifier.  NLP Project using PySpark.  Preprocessing Data and Clean it.  Using TF_IDF, Tokenizer, NaiveBayes classifier model.  Accuracy F1_Score.

nlp_text_representation icon nlp_text_representation

In Natural Language Processing (NLP) the conversion of raw-text to numerical form is called Text Representation and believe me this step is one of the most important steps in the NLP pipeline as if we feed in poor features in ML Model, we will get poor results. In computer science, this is often called “garbage in, garbage out.” I observed in NLP feeding a good text representation to an ordinary algorithm will get you much farther compared to applying a topnotch algorithm to an ordinary text representation. In this notebook, I will discuss various text-representation schemes with their advantages and disadvantages so that you can choose one of the schemes which suit your task most. Our main objective is to transform a given text into numerical form so that it can be fed into NLP and ML algorithms.

it some work and practise on pyspark (big_data)

tweets_sentiment_analysis icon tweets_sentiment_analysis

In this notebook I used 2 different text representation teqniques (cout_vectorizer , TF-IDF) , with 2 diff ML models (logestic regression , SVM classifier) , and at least i used CNN technique
