Python for Data Science

Learn programming in Python, how to work with Jupyter Notebook and to use powerful Python libraries like Pandas and NumPy to explore and analyse big data sets. Collect data from various sources, including CSV files, SQL queries on relational databases, Google Big Query, APIs and Web scraping.

Relational Database & SQL

Learn how to formulate a good question and how to answer it by building the right SQL query. This module will cover schema architecture and then dive deep into the advanced manipulation of SELECT to extract useful information from a stand-alone database or using a SQL client software like DBeaver.

Data Visualization

Make your data analyses more visual and understandable by including data visualisations in your Notebook. Learn how to plot your data frames using Python libraries such as matplotlib and seaborn and transform your data into actionable insights.

Statistics, Probability, Linear Algebra

In Tokyo you will learn about the underlying math behind all the libraries and models used in the bootcamp. Become comfortable with the basic concepts of statistics & probabilities (mean, variance, random variable, Bayes’s Theorem, etc.) and with matrix computation, at the core of numerical operations in libraries like Pandas and Numpy.

c pulse Statistical inferences

You'll learn how to structure a Python repository with object-oriented programming in order to clean your code and make it re-usable, how to survive the data preparation phase of a vast dataset, and how to find and interpret meaningful statistical results based on multivariate regression models.

speaker Communication

Data analysts are meant to communicate their findings to non-technical audiences: You will learn how to create impact by explaining your technical insights and turn them into business decisions using cost/benefits analysis. You'll be able to share your progress, present and compare your results to your teammates.

Preprocessing and Supervised Learning

Learn how to explore, clean, and prepare your dataset through preprocessing techniques like vectorisation. Get familiar with the classic models of supervised learning - linear and logistic regressions. Learn how to solve prediction and classification tasks with the Python library scikit-learn using learning algorithms like KNN (k-nearest neighbors).

Generalisation and Overfitting

Implement training and testing phases to make sure your model can be generalised to unseen data and deployed in production with predictable accuracy. Learn how to prevent overfitting using regularization methods and how to chose the right loss function to improve your model's accuracy.

Performance Metrics

Evaluate your model's performance by defining what to optimise and the right error metrics in order to assess your business impact. Improve your model's performance with validation methods such as cross validation or hyperparameter tuning. Finally, discover a powerful supervised learning method called SVM (Support Vector Machines).

Unsupervised Learning & Advanced Methods

Move to unsupervised learning and implement methods like PCA for dimensionality reduction or clustering for discovering groups in a data set. Complete your toolbelt with ensemble method that combine other models to improve performance, such as Random Forest or Gradient Boosting.

Neural Networks

Unveil the magic behind Deep Learning by understanding the architecture of neural networks (neurons, layers, stacks) and their parameters (activations, losses, optimisers). Become autonomous to build your own networks, especially to work with images, times and text, while learning the techniques and tricks that make Deep Learning work.

Computer Vision

Go further into computer vision with Convolutional Neural Networks, architectures designed to make the most out of images. Improve your model generalisation thanks to data augmentation techniques and implement advanced methods to benefit from state-of-the-art architectures thanks to Transfer Learning methods.

Times-Series & Text data

Get comfortable into managing sequential data and text (sequence of words) by transforming them into appropriate inputs. Leverage the power of Recurrent Neural Networks to forecast future values and perform valuable Natural Language Processing.

Deep Learning made easy

Discover the Keras Deep Learning library which enables you to prototype easily while having the flexibility to tune precisely your neural network. Moreover, Google Colab will greatly speed up the computational time thanks to dedicated GPUs.

Machine Learning Pipeline

Move from Jupyter Notebook to a code editor and learn how to set up a machine learning project in the right way in order to quickly and confidently iterate. Learn how to convert a machine learning model into a model with a robust and scalable pipeline with sklearn-pipeline using encoders and transformers.

Machine Learning workflow with MLflow

Building a machine learning model from start to finish requires a lot of data preparation, experimentation, iteration, and tuning. We'll teach you how to do your feature engineering and hyperparameter tuning in order to build the best model. For this, we will leverage a library called MLflow.

Deploying to production with Google Cloud Platform

Finally, we'll show you how to deploy your code and model to production. Using Google Cloud AI Platform, you'll be able to train your model at scale, package it and make it available to the world. Cherry on top, you will use a Docker environment to deploy your own RESTful Flask API which could be plugged into any front-end interface.

Solve real-world problems with Data!

The final weeks of the course will culminate in the delivery of your capstone project! Working collaboratively in small teams, the project will allow you to utilise all the skills you have learned throughout the bootcamp in order to solve a real world data science problem.

  • Collaborate efficiently in teams of 3-4 people on a real data science project through a common Python repository.
  • Use a mix of your own datasets (if you have any from your company / non-profit organisation) and open-data repositories (Government initiatives, Kaggle, etc.)
  • Put into practice all the tools, techniques, and methodologies covered in the Data Science Course.
  • Invent, pitch, design, code, and deploy your fully functioning Data Project, to be used in real-life scenarios and as a portfolio-ready application to showcase your new data science skill set.

Admission & prep work

Our Data Science course requires a basic level of Python & Mathematics. As we want all of our students to succeed, you'll be able to test your level and refresh your skills before the Bootcamp starts.

Admission prerequisites in Python & Maths
  • Python prerequisites

    You'll need to be comfortable with data types & variables, conditions, loops, functions and data structures (List & Dictionary).

  • Mathematics prerequisites

    You'll need a High School level of Maths, meaning you will be comfortable with functions, derivatives, and systems of linear equations.

  • Testing your skills

    After a chat with our Admissions team, you will receive a Python & Mathematics Quiz to help you and the Admissions team better understand your current level in Python & Maths. We'll also provide you with a set of additional free learning resources to help you match the prerequisite level for the Bootcamp.

Post-admission prep work

Once you have been accepted onto the Data Science Bootcamp (congrats!), you'll receive ~ 40h of online learning resources. We require all of our students to complete this before the Bootcamp starts, either at their own pace or during our Data Prep Week.

For part-time Data Science students, the Data Prep Week can be stretched over 2 weeks (evenings and Saturdays) prior to the start of the bootcamp.

Any questions about our program in Tokyo

If you got here, it means that you have questions about Le Wagon: how to apply, who can join, what you’ll learn… Good! We have the answers.

Do you support job search after the program?

At the end of each bootcamp, we organize a 10th optional week, the Career Week, dedicated to helping our students prepare their job search and upcoming career. This Career Week consists of practical support on how to build a resume, creating or updating a LinkedIn profile and a portfolio page, or preparing for technical interviews.

We also connect our fresh graduates with a network of over 50 startups and recruiting agencies, and regularly introduce new job opportunities through a dedicated Slack channel.

This article extensively explains what to expect from our Career Week.

Keep in mind that finding a job at the end of our program will strongly depend on your dedication and motivation before, during and after the bootcamp. Our most successful graduates have a genuine interest in tech and programming, and never miss an opportunity to build up their skills and broaden their knowledge.

You can refer to this article written by one of our alumni for a step-by-step guide on how to land a job in Tokyo.

Can I pay the tuition in installments?

Our standard payment plan is as follows:
- Deposit upon contract signature (⅓ of the total tuition)
- Remaining balance due during the first month of the bootcamp

We do offer a payment option in three installments without extra fees for specific cases, upon request.
Please note that your spot will only be secured once we have received your deposit.

You can find additional details regarding payment options by following this link.

Do I need to speak Japanese to join the bootcamp or find a job in Tokyo?

You do not need to be able to speak Japanese to join our program: all our curriculum, teaching platform, content and events are in English.

While speaking Japanese opens up opportunities when looking for a job, there are more and more companies in Tokyo ready to hire non-Japanese speakers. That said, JLPT N4 or N3 will be a proof that you are committed to living in Japan, and greatly helps communication within most companies.

What to expect from the enrollment interview?

The interview usually lasts one hour. We conduct it in two 30-min parts, first one focusing on your background and motivation, and second more "formal" one about maths and programming:
Maths questions are senior high school level maximum (e.g. derivatives, mean, simple statistical concepts)
Programming questions are here to check your understanding of basic programming concepts (e.g. variable, data types, simple algos)

The best way to prepare for this interview is to go through our prep work. There is no failing! If we think you need to study further, we will let you know which parts to improve, and you can apply for our next session.

What type of visa do I need to attend Le Wagon in Japan?

If you’re attending our 9-week full-time program, you only need to make sure you are eligible for a 90-day tourist visa. If your country is not in the list of eligible nationalities, we can provide supporting documents to apply for a short-term stay visa at your local Japanese embassy.

If you’re attending our 24-week part-time program, it’s important to check if you are authorized to stay in the territory for all program’s length.

What is the estimated cost of living in Tokyo?

Tokyo always had a reputation for being an expensive city to live in. The good news is, this is just a reputation. You can refer to this article for an estimated accommodation, food and transportation budget.
