To delete a dataset, go to the storage account by using the Azure portal or Azure Storage Explorer and manually delete those assets. Next steps Learn the fundamentals of predictive analytics and machine learning withTutorial: Predict automobile price with the designer...
1. Dataset and Data Files In machine learning, you fit a model on a dataset. This is the table-like set of numbers where each row represents an observation and each column represents a feature of the observation. For example, below is a snippet of the Iris flowers dataset: 1 2 3 4 ...
Learn how to use Apache Spark MLlib to create a machine learning application. The application does predictive analysis on an open dataset. From Spark's built-in machine learning libraries, this example uses classification through logistic regression.ML...
Chapter 1, Getting Started with Machine Learning and Python, will be the starting point for readers who are looking forward to entering the field of machine learning with Python. It will introduce the essential concepts of machine learning, which we will dig deeper into throughout the rest of ...
DataFlair links to over 70 machine learning datasets, and includes useful information like the source code as well as project ideas. For example, in a listing for a dataset that features handwritten digits, DataFlair suggests creating an image classification algorithm to recognize handwritten digits...
