Data Science: NLP : Sentiment Analysis – Model Building

In this course I will cover, how to develop a Sentiment Analysis model to categorize a tweet as Positive or Negative using NLP techniques and Machine Learning Models. This is a hands on project where I will teach you the step by step process in creating and evaluating a machine learning model and finally deploying the same on Cloud platforms to let your customers interact with your model via an user interface.

This course will walk you through the initial data exploration and understanding, data analysis, data pre-processing, data preparation, model building, evaluation and deployment techniques. We will explore NLP concepts and then use multiple ML algorithms to create our model and finally focus into one which performs the best on the given dataset.

At the end we will learn to create an User Interface to interact with our created model and finally deploy the same on Cloud.

I have splitted and segregated the entire course in Tasks below, for ease of understanding of what will be covered.

Task 1  :  Installing Packages.

Task 2  :  Importing Libraries.

Task 3  :  Loading the data from source.

Task 4  :  Understanding the data

Task 5  :  Preparing the data for pre-processing

Task 6  :  Pre-processing steps overview

Task 7  :  Custom Pre-processing functions

Task 8  :  About POS tagging and Lemmatization

Task 9  :  POS tagging and lemmatization in action.

Task 10 :  Creating a word cloud of positive and negative tweets.

Task 11 :  Identifying the most frequent set of words in the dataset for positive and negative cases.

Task 12 :  Train Test Split

Task 13 :  About TF-IDF Vectorizer

Task 14 :  TF-IDF Vectorizer in action

Task 15 :  About Confusion Matrix

Task 16 :  About Classification Report

Task 17 :  About AUC-ROC

Task 18 :  Creating a common Model Evaluation function

Task 19 :  Checking for model performance across a wide range of models

Task 20 :  Final Inference and saving the models

Task 21 :  Testing the model on unknown datasets

Task 22 :  Testing the model on unknown datasets – Excel option

Task 23 :  What is Streamlit and Installation steps.

Frequently Asked Questions

How long do I have access to the course materials?

You can view and review the lecture materials indefinitely, like an on-demand channel.

Can I take my courses with me wherever I go?

Definitely! If you have an internet connection, courses on Udemy are available on any device at any time. If you don’t have an internet connection, some instructors also let their students download course lectures. That’s up to the instructor though, so make sure you get on their good side!
