Welcome to Yet Another ML Recipe! In this Medium guide, I'll walk you through a simple yet comprehensive approach to understanding the core concepts of Machine Learning (ML). Whether you're a novice developer taking your first steps into the world of ML or a seasoned professional seeking to deepen your knowledge, this guide is tailored for you. We'll be focusing on sentiment analysis, a fundamental task in ML, where we predict whether a given sentence expresses a positive or negative sentiment.
This guide is designed for:
- New developers eager to write their first ML code.
- Seasoned professionals looking to explore the domain of ML.
- Movie enthusiasts curious about how sentiment analysis can gauge audience reactions.
- Anyone with a keen interest in understanding the basics of ML.
You will embark on a journey to predict the sentiment of movie reviews using a simple ML algorithm. Through step-by-step instructions, you'll gain hands-on experience in data collection, preprocessing, model training, and evaluation.
Before diving into the code, ensure you have:
- A stable internet connection.
- Basic knowledge of the Python programming language (though I'll guide you through the process).
We'll be using Google Colab, a hassle-free platform for running Jupyter notebooks without any prior setup.
- Data Collection: Download the IMDB Dataset of 50K Movie Reviews from Kaggle.
- Importing the Data: Store the dataset in a Pandas DataFrame for further processing.
- Visualizing the Data: Gain insights into the distribution of positive and negative sentiments.
- Data Preprocessing: Clean the data by removing unnecessary elements and standardizing text.
- Train-Test Split: Divide the data into training and testing sets for model evaluation.
- Vectorization: Convert text data into numerical vectors using TF-IDF vectorization.
- Model Training: Train a Logistic Regression model on the training data.
- Testing the Model: Evaluate the model's performance on the testing data.
- Hyperparameter Tuning: Fine-tune model hyperparameters for optimal performance.
- Model Comparison: Compare the accuracies of different models to choose the best one.
- Explore alternative ML models like k-Nearest Neighbors (kNN) for sentiment analysis.
- Experiment with different hyperparameters to optimize model performance.
- Extend the application of ML beyond sentiment analysis to various domains.
