Data Scientist with Python

Data pipelines with machine learning algorithms and Python - the online training with certificate of completion

This continuing education is held in German.
Being able to process and analyze data automatically and in real time and derive insights from it is one of the key requirements of companies. Building the data pipelines for this is the task of data scientists - a professional field that is currently in high demand and offers great opportunities. This certified online training course enables you to set up data mining processes, apply machine learning algorithms, create predictive models and implement them productively in automated workflows. The course uses the Python programming language with its leading machine learning libraries. This online course is designed so that you can learn flexibly and at your own pace. You can expect videos, interactive graphics, texts and many practical exercises with extensive data sets and coding tasks. Experienced data analysts are on hand as mentors to answer your questions.

The online training course has been tested and approved by the State Central Agency for Distance Learning (ZFU) in Cologne under the number 73597.

How do you learn in the course?

This online course offers you a particularly practice-oriented learning concept with comprehensive self-study units and a team of mentors who are available to you at all times. A new chapter is activated for you every week. With a time budget of around 6 hours per week, you are sure to reach your goal in 17 weeks. This is how you learn in the course:

Placement test: In an onboarding meeting at the beginning of the course, you and the mentoring team will determine what knowledge you already have and which parts of the course you should pay particular attention to. This will prepare you optimally for learning in the self-study units.

Data Lab: In the course's learning environment, you can expect videos, interactive graphics, text and, above all, many practical exercises with comprehensive datasets and coding tasks. You carry these out directly in the browser - without installation or configuration effort and with direct success control.

Mentor team: Your learning coaches are available to answer any questions you may have. They are experienced data analysts who will be happy to help you - via chat, audio or video call.

Webinars: Once a week, you have the opportunity to take part in webinars and immerse yourself in selected special topics of data analysis.

Career coaching: What professional goals are you pursuing with your further training and how can you achieve them? A team of mentors is available to help you achieve your career goals.

Final project: In your own data project, you will work independently through the entire data pipeline and answer typical questions. At the end, you will present your project in a 1-to-1 feedback session with your mentoring team.

Certificate: After the final project, you will receive your official certificate as a Data Analyst with Python.

This online training is provided by our partner StackFuel GmbH. StackFuel specializes in training courses on data literacy, data science and AI.

Your benefit

In this practice-oriented training course, you will learn how to carry out data analyses with large data sets independently.

You will learn how to use Python competently, how to use the programming language for data evaluation and how to create effective visualizations.

You will learn how to connect a wide variety of data sources, filter data in them and merge them.

You will learn comprehensive methods, algorithms and technologies of machine learning and how to use them with Python packages.

You will learn everything you need to know about the use of deep learning and create an artificial neural network with several layers.

After the training, you will be able to examine company data, visualize it in a meaningful way and make it interactively accessible in dynamic dashboards.

The technical entry hurdles are minimized by the use of Jupyter notebooks, with which you can carry out the programming exercises directly in the browser.
