getPoincareDistanceVec: Calculating Poincare distance between two vectors.

In hwchang1201/poincare.embeddings: R-package implementation of Poincaré Embeddings for Learning Hierarchical Representations.

Description

This function measures Poincare distance between two vectors. Please refer to 'vignette' to find the equation for the Poincare distance and detailed ideas.

Usage

getPoincareDistanceVec(theta_i, theta_j)

Arguments

theta_i	- A N x 1 vector with N : Embedding space dimension. Each of theta works as proxy of an entity in tree-shape dataset.
theta_j	- A N x 1 vector with N : Embedding space dimension. Each of theta works as proxy of an entity in tree-shape dataset.

Value

A poincare distance between theta_i and theta_j.

Examples

getPoincareDistanceVec(c(0, 0), c(0.1, 0.5))
getPoincareDistanceVec(c(0.4, 0), c(0.1, 0.5))
