Implementing Multilabel Classifier Using the mlr and OpenML Packages
We will now see how to train a multilabel classifier using the mlr and OpenML packages. First, we will download the scene dataset from OpenML.
Exercise 102: Downloading the Scene Dataset from OpenML
In this exercise, we will download the scene dataset and set it up for further analysis.
Perform the following steps to complete the exercise:
In order to download the scene dataset through OpenML API, first create an account in the OpenML website at https://www.openml.org/register. The registration process involves verifying your email address, post which you will get the access to the API keys.
Figure 9.8: The OpenML registration page.
After logging in to your account, navigate to your account and select the API AUTHENTICATION option.
On the API Authentication page, select and copy-paste the API key from the API key section. The authors of the Multilabel Classification with R Package mlr paper uploaded a bunch of datasets with a...
