Data Science 102

December 8 | S$2000

Begins December 8, 2018 | 7 Weeks (Bi-Weekly For December 2018 Only) | S$2000 (Up to 100% Subsidies Available)

Schedule: 8th Dec 18 to 6th Jan 19 (Bi-weekly classes)

Learn Machine Learning Using Python

What is DS102?

Data science and analytics are the current hot topics in both academia and industry. This course aims to introduce data science and analytics to students with no relevant background. Through this course, students will learn the types of problems that can be solved by data science and analytics.

The students will also be introduced to the three broad topics in data science and analytics: data management, data visualisation and machine learning techniques. Learning in this course will be very “hands-on” and classes are designed to allow students to practise the techniques and concepts discussed in the lectures.

Data Science Track

The Data Science 101 (DS101) course is built for beginners with no background in programming. Finishing DS101 prepares students for the Data Science 102 (DS102) course, where they learn about data analytics toolsets in Python. DS102 can also be taken by software engineers who are already well versed in Python. In our master class, Data Science 103, students will graduate with data know-how in an organisation setting and be certified as a data analyst by our academy.

DS102 Course Details

DS102 will be held once a week over 7 consecutive weeks. Each session would be 3 hours long held at 991D Alexandra Road #01-22/23 Singapore 119972. The course fees is $2000 before subsidy however Singaporeans and PRs are eligible for subsidies of up to 100%.

This course is an advance Python course and trainees are required to have the prerequisites before commencing the course. These prerequisites are also covered in our DS101 series.

Prerequisities

DS102 is our advanced course after DS101 and hence all students are already expected to have a good working knowledge of Python programming. If you find that you do not have these competencies, consider taking the DS101 course instead.
