Gini index based initial coin offering mechanism

Initial Coin Offering and Platform Building∗

In an initial coin offering (ICO), a company (or an open-source project) raises funds by pre-selling access to a later product or service. We present a model that rationalizes the use of ICOs for launching peer-to-peer platforms: by adding dynamics to a platform launch, ICOs can 1) solve a coordination failure inherent in many platforms with network effects; and 2) harness the “wisdom of the cr...

A truthful Screening Mechanism for Improving Information Asymmetry in Initial Public Offering Transactions

The Gini Index of Speech

In which representation is speech most sparse? Time-scale? Time-frequency? Which window generator and length should be used to create the sparsest decomposition? To answer these questions, we propose the Gini index, which is twice the area between the Lorenz curve and the 45 degree line, as a measure of signal sparsity. The Gini index, introduced in 1912, is one of the most common measures of i...

An Improved Text Classification Method Based on Gini Index

In text classification, the purity of the Gini index can be used. When purity value is greater, the characteristic of the information contained in the attribute is higher, and the feature distinguishing capability is stronger. But using the Gini purity formula on feature weight, the classification result is not very good, one of the main reasons is those rare words only appearing in one categor...

The Gini Index and Measures of Inequality

The Gini index is a summary statistic that measures how equitably a resource is distributed in a population; income is a primary example. In addition to a self-contained presentation of the Gini index, we give two equivalent ways to interpret this summary statistic: first in terms of the percentile level of the person who earns the average dollar, and second in terms of how the lower of two ran...
