Outline data preparation for machine learning, detailing principles, concepts, and steps, including the tabular format and upcoming time series concepts.
Learn data preparation for machine learning with a focus on tabular data, targets, units of analysis, and supervised learning approaches like classification and regression, highlighting data quality’s impact.
Assess a preformatted tabular dataset with a defined target variable for a supervised Driverless AI experiment, where most preprocessing is automatic and you can apply custom data recipes.
Learn best practices for data preparation in machine learning, from training on large datasets to scoring with a single row, while avoiding target leakage with Driverless AI to prevent overfitting.
Learn time series data preparation with Driverless AI by structuring multivariate datasets with a date column and autoregressive target, plus grouping, external features, and split by time.
This course, a component of H2O's University’s certification program, aims to equip participants with the requisite skills to effectively utilize our H2O's Driverless AI tool. Jonathan Farinela, Solutions Engineer at H2O, will emphasize the crucial role of data quality in achieving successful outcomes, while also elucidating the principles and procedures of data preparation.
The course is divided into two main sections:
In the initial section, participants will delve into the importance of the tabular format in classical machine learning. They will also grasp the distinction between supervised and unsupervised learning, along with common methodologies like classification and regression. The significance of defining the unit of analysis in dataset construction will be highlighted. Moreover, participants will witness demonstrations of data preparation within Driverless AI, showcasing its ability to automate preprocessing tasks and allow customization using Python code.
Transitioning to the second section, the course will concentrate on time series data preparation. Fundamental aspects of time series problems will be explored, including the necessity of a date column and understanding the autoregressive nature of such data. The course will also address challenges associated with handling multiple series within a dataset and provide best practices for improving model performance. Jonathan will exemplify dataset preparation and splitting techniques tailored for time series analysis using the capabilities of Driverless AI.
Enjoy the learning journey!
