20 Jan 2025 - 23 Jan 2025 | DSCI-272: Predicting with Cloudera Machine Learning - Italian |
Description
Enterprise data science teams need collaborative access to business data, tools, and computing resources required to develop and deploy machine learning workflows. Cloudera Machine Learning (CML), part of the Cloudera Data Platform (CDP), provides the solution, giving data science teams the required resources.
This course covers machine learning workflows and operations using CML. Participants explore, visualize, and analyze data. You will also train, evaluate, and deploy machine learning models.
The course walks through an end-to-end data science and machine learning workflow based on realistic scenarios and datasets from a fictitious technology company. The demonstrations and exercises are conducted in Python (with PySpark) using CML.
Audience and prerequisites
The course is designed for data scientists who need to understand how to utilize Cloudera Machine Learning and the Cloudera Data Platform to achieve faster model development and deliver production machine learning at scale. Data engineers, developers, and solution architects who collaborate with data scientists will also find this course valuable.
Participants should have a basic understanding of Python or R and some experience exploring and analyzing data and developing statistical or machine learning models. Knowledge of Spark, Hadoop, or the Cloudera platform is not required.
Objectives
Students who successfully complete this course will be able to:
- Utilize Cloudera SDX and other components of the Cloudera Data Platform to locate data for machine learning experiments.
- Use an Applied ML Prototype (AMP).
- Manage machine learning experiments.
- Connect to various data sources and explore data.
