Research of Software Solutions to Determine the Optimal Solution for the Specified Parameters

This paper examines the study of software solutions for optimizing decision-making, in particular, choosing the most appropriate clothing size. The purpose of the work is to conduct research and compare three machine learning methods regarding the issue of predicting clothing size. Software solutions were developed based on an open data set containing user measurements, information about products, sizes and types of ordered goods, reviews and comments on orders. During the work, three machine learning algorithms were implemented: the k-nearest neighbor method, the use of a multilayer fully connected neural network, and the use of a neural network with funny data inputs. Possible solutions and architectures of neural networks are presented and tested regarding the issue of optimizing decision-making regarding size according to the criteria of the user himself. It is proposed to use a neural network with mixed data inputs in the JavaScript programming language using TensorFlow.JS, where mixed inputs mean data on the user’s personal measurements and comments left on the compliance of the declared size. The subsequent implementation of the proposed solution is possible as an independent web application or to integrate the module into web sites with the appropriate subject.
