diemsim 0.0.1

A Python Library Implementing Dimension Insensitive Euclidean Metric

diemsim

diemsim is an optimized Python library to compute "Dimension Insensitive Euclidean Metric (DIEM)" which surpasses Cosine similarity for multidimensional comparisons. Benchmarking

Latency Benchmarking

Our proposed approaches,
Compact Vectorization optimizes latency of the existing function 'DIEM_Stat' by around 46.50%
Compact Optimized getDIEM optimizes latency of the existing function 'getDIEM' by 34.27%

Getting Started

Install the package via pip:

pip install diemsim

Usage

from diemsim import DIEM

N= 12
maxV= 1
minV= 0
n_iter= int(1e5)

S1= np.random.rand(N, 1) * (maxV - minV) + minV
S2= np.random.rand(N, 1) * (maxV - minV) + minV

# Initialize DIEM
diem= DIEM( N= N, maxV= maxV, minV= minV, n_iter= n_iter ) 

# Compute DIEM value
value= diem.sim( S1, S2)

print( "Output Value: ", value )
