Datasets

Bananas

Bananas dataset.

An artificial dataset where instances belongs to several clusters with a banana shape. There are two attributes that correspond to the x and y axis, respectively.

Name  Bananas

Elec2

Electricity prices in New South Wales.

This is a binary classification task, where the goal is to predict if the price of electricity will go up or down.

This data was collected from the Australian New South Wales Electricity Market. In this market, prices are not fixed and are affected by demand and supply of the market. They are set every five minutes. Electricity transfers to/from the neighboring state of Victoria were done to alleviate fluctuations.

  Name  Elec2

Phishing

Phishing websites.

This dataset contains features from web pages that are classified as phishing or not.

Name  Phishing

SMTP

SMTP dataset from the KDD 1999 cup.

The goal is to predict whether or not an SMTP connection is anomalous or not. The dataset only contains 2,211 (0.4%) positive labels.

  Name  SMTP
