Data Science and Machine Learning with Python

Delegates must be existing Python Data users who have attended;

Python for Data Handling (QADHPYTHON)

or have a similar level of knowledge with NumPy and Pandas.

Additionally, we recommend that delegates have attended;

Introduction to Data Science for Data Professionals (QAIDSDP)

in order to understand key data science, machine learning, and AI governance requirements before developing Machine Learning models.

Target Audience

Members of the audience are required to have a some technical expertise such as table structure, working with tabular data in Python, and simple data analysis.

They may be Mid/Senior Leadership seeking a greater understanding of how to implement Data Science within their organization.

They may come from other technical backgrounds such as Data Analysts, Software Developers, and Data Engineers who either work with Data Scientists or are using this course in their journey towards training as a Data Scientist.

In the latter case, audience members may ask for recommendations for their next steps in training towards becoming Data Scientists. We recommend the following refreshed courses which are due to launch in 2023 and 2024 in this suggested sequence:

• Statistics for Data Analysis in Python
• Time Series and Forecasting with Python
• Maths and Statistics for Data Science with Python
• Practical Big Data Analytics (with Python and Spark)
• Generative AI Essentials
• Fundamentals of Deep Learning with Python (followed by selected Python & NVIDIA training)

• Introduction to Data Science & Machine Learning
• Introduction to Python for Data Science
• Descriptive & Inferential Statistics with Python
• Preprocessing Data for Analysis
• Supervised Learning: Regression
• Supervised Learning: Classification
• Model Selection & Evaluation
• Unsupervised Learning
• Ethics for Data Scientists
• Deploying Models & Insights
• Where to Go Next
