Syllabus
Course overview and goals
In the current society, it is essential in all fields to appropriately exploit "big data" for finding rules and/or making predictions/decisions. This course aims to help students to manipulate computer software tools for data analysis to get new findings.
Course description and aims
Students will be able to understand the basis of data processing mechanisms and make use of various data analysis software tools appropriately.
Keywords
classification, clustering, principal component analysis, dimension reduction, training/generalization errors, cross validation
Competencies
- Specialist skills
- Intercultural skills
- Communication skills
- Critical thinking skills
- Practical and/or problem-solving skills
Class flow
In class, students are required to solve exercise problems that are linked with the contents of taught course ``XCO.T487 Fundamentals of data science".

Prerequisites
When you apply this exercise, it is strongly recommended to take "XCO.T487 Fundamentals of Data Science'', "XCO.T489 Fundamentals of Artificial Intelligence" and "T490 Exercises in Fundamentals in Artificial Intelligence" of the same quarter of the same year in parallel. In the case of students of Tokyo Tech Academy for Convergence of Materials and Informatics, take “TCM.A404 Materials Informatics” instead of “XCO.T487 Fundamentals of data science” and “XCO.T488 Exercises in fundamentals of data science."
Students of the doctor course are required to register XCO.T678 "Exercises in fundamentals of advanced data science" instead of XCO.T488"Exercises in fundamentals of data science."

Exercises are carried out using Google Colaboratory. Students are required to get Google accounts and to get ready for using functions of "file upload/download" in Google Drive.
At the Suzukakedai Campus, the exercise room is located inside the library, so a student ID card is required for entry.
To use the PCs in the exercise room, you need to check your “Login ID” and set a “Password” through the Education Computer System on the Tokyo Tech Portal. Please make sure to complete this procedure before the exercise begins.
