Curriculum
Data Science with Python Basics
16 Hours
Foundational Module
Python for Data Science
A beginner-friendly module that teaches you how to code in Python and work efficiently with big datasets using Google’s Colab. Understand how businesses store, extract and manipulate data through industry use cases and case studies.
Analyzing Data with Python
Learn how to analyze and harvest clean data sets and create data frames to run basic analysis as well as to perform data reporting using powerful data science libraries like Pandas and Numpy to gain actionable insights for your business.
Web Scraping with APIs
Learn how to navigate, collect and organize data from various sources like CSV files, APIs. You’ll leverage on existing datasets, scrape web data and learn to access useful information in these data structures.
Intro to Data Visualization
Understand how data scientists present and visualize large datasets across industries. Leverage on Matplotlib to create descriptive and interpretable visuals, enabling you to easily extract relevant information, better understand the data, and make effective decisions.
Advanced Data Analysis and Data Engineering
16 Hours
Intermediate Module
Data Crawling and Data Mining
Learn how to extract and save any data on any websites like Google and Yahoo, process the HTML codes, and build automated tools to crawl the web at scale. From texts to images, fetch and display desired information for your own use with libraries like BeautifulSoup.
Advanced Data Visualisation
Bridge the gap between data and insights and create informative and striking statistical graphics with libraries like Seaborn and Plotly. Draw effective conclusions and analysis by visualizing the multidimensional relationships among the data samples, conduct correlation analysis and even statistical data exploration.
Data Engineering and Regression Modeling
16 Hours
Intermediate Module
Data Cleaning and Supervised Learning
Learn how to explore, clean and model data for supervised machine learning using preprocessing techniques. Implement linear and logistic regression, and build classification models with decision trees like Random Forest to make predictions with Python machine learning library sci-kit learn and k-nearest neighbors algorithm.
Unsupervised Learning
Learn how to find associations, patterns, and relationships present in data using clustering techniques and dimensionality reduction techniques as well as matrix factorization to break dataset in groups.
Generalization and Overfitting in Machine Learning
Determine whether a model is good or not by implementing both a training set and a test set to ensure its ability to adapt and generalize to new, unseen data. Learn how the reward-punishment mechanism works to penalize models to prevent overfitting using regularization and cross-validation methods to improve model accuracy.
Deep Learning and Neural Networks
16 Hours
Advanced Module
NLP and Image Classification
Learn how to extract and identify information from unstructured text using text mining and Natural Language processing (NLP) techniques to make sense out of data, e.g. how Siri is powered. Know how to pre-process raw image data using normalisation and standardisation techniques as a part of data preparation for deep learning.
Neural Networks
Understand the architecture and key parameters in a neural network and apply different forms of machine learning algorithm like Recurrent Neural Networks (RNNs) for sequential data such as time series and financial data; Natural Language Processing (NLP) for text classification and generation and Convolutional Neural Networks (CNN) for image classification.
Deep Learning with Keras
Hands-on with popular machine learning tools like Google’s Tensorflow; and leverage on the Keras Library to build, train and test your first deep learning model.
Deployment of Machine Learning
16 Hours
Advanced Module
Final Project
In this final module, you’ll have equipped yourself with skills to comb over available data and be able to implement practical machine learning techniques to make predictions as well as deliver insights as well as communicate findings using data visualisation techniques.
It's your time to build, train and deploy your model at scale now and change the world!

Proud Preface Grads
Feedbacks from happy learners inspire us everyday
As a startup founder without technical background, Preface's programming course gave me solid understanding & practical skills about coding, and enabled me to build an effective communication channel with my engineers. Preface is definitely the go-to upskill platform for anyone in the field.
Vincent So
Founder at Inspect Element
I used to think coding is the new & hip trend that only fits young people, but Preface has proven me wrong. The systematic & practical learning system helped me to get my hands on programming seamlessly, and to actually apply to work. How much I love Preface? I applied to both courses.
