Vector Quantized AutoEncoder is proposed as an unsupervised clustering method. The document proposes the basic model, defines distance measurement, and shows a concrete example using the MNIST dataset. Source code for experiments is available online. Experiments are conducted to analyze different initialization methods for quantization weights, the effect of varying the number of quantization clusters, and comparing cosine distance and Euclidean distance metrics.
FIDUCIAL POINTS DETECTION USING SVM LINEAR CLASSIFIERScsandit
Currently, there is a growing interest from the scientific and/or industrial community in respect
to methods that offer solutions to the problem of fiducial points detection in human faces. Some
methods use the SVM for classification, but we observed that some formulations of optimization
problems were not discussed. In this article, we propose to investigate the performance of
mathematical formulation C-SVC when applied in fiducial point detection system. Futhermore,
we explore new parameters for training the proposed system. The performance of the proposed
system is evaluated in a fiducial points detection problem. The results demonstrate that the
method is competitive.

Bayesian Autoencoders for anomaly detection in industrial environmentsBang Xiang Yong
Seminar for Manufacturing Analytics Group on my PhD thesis : Bayesian autoencoders
Three main contributions are:
1. Probabilistic formulation of autoencoder focusing on likelihood and the need for bottleneck.
2. Uncertainty quantification for anomaly detection
3. Explainability for anomaly detection
As part of our team's enrollment for Data Science Super Specialization course under UpX Academy, we submitted many projects for our final assessments, one of them was Telecom Churn Analysis Model.
The input data was provided by UpX academy and language we used is R. As part of the project, our main objective was :-
-> To predict Customer Churn.
-> To Highlight the main variables/factors influencing Customer Churn.
-> To Use various ML algorithms to build prediction models, evaluate the accuracy and performance of these models.
-> Finding out the best model for our business case & providing executive Summary.
To address the mentioned business problem, we tried to follow a thorough approach. We did a detailed level Exploratory Data Analysis which consists of various Box Plots, Bar Plots etc..
Further we tried our best to build as many Classification models possible which fits our business case (Logistic Regression/kNN/Decision Trees/Random Forest/SVM) and also tried to touch Cox Hazard Survival analysis Model. Later for every model we tried to boost their performances by applying various performance tuning techniques.
As we all are still into our learning mode w.r.t these concepts & starting new, please feel free to provide feedback on our work. Any suggestions are most welcome... :)
Thanks!!

One of the primary drawbacks plaguing wider acceptance of surrogate models is their low fidelity (in general), which can be in a large part attributed to the lack of quantitative guidelines regarding the suitability of different models for diverse classes of problems. In this context, model selection techniques are immensely helpful in ensuring the selection and use of an optimal model for a particular design problem. A novel model selection technique was recently developed to perform optimal model search at three levels: (i) optimal model type (e.g., RBF), (ii) optimal kernel type (e.g., multiquadric), and (iii) optimal values of hyper-parameters (e.g., shape parameter) that are conventionally kept constant. The maximum and the median error measures to be minimized in this optimal model selection process are given by the REES error metrics, which have been shown to be significantly more accurate than typical cross-validation-based error metrics. Motivated by the promising results given by REES-based model selection, in this paper we develop a framework called Collaborative Surrogate Model Selection (COSMOS). The primary goal of COSMOS is to allow the selection and usage of globally competitive surrogate models. More specifically, this framework will offer an open online platform where users from within and beyond the Engineering Design (and MDO) community can submit training data to identify best surrogates for their problem, as well as contribute new and advanced surrogate models to the pool of models in this framework. This first-of-its-kind global platform will facilitate sharing of ideas in the area of surrogate modeling, benchmarking of existing surrogates, validation of new surrogates, and identification of the right surrogate for the right problem. In developing this framework, this paper makes three important fundamental advancements to the original REES-based model selection - (i) The optimization approach is modified through binary coding to allow surrogates with differing numbers of candidate kernels and kernels with differ- ing numbers of hyper-parameters. (ii) A robustness criterion, based on the variance of errors, is added to the existing criteria for model selection. (iii) Users are allowed to perform model selection for a specified region of the input space and not only for the entire input domain, subject to empirical constraints that are related to the relative sample strength of the region. The effectiveness of the COSMOS framework is demonstrated using a comprehensive pool of five major surrogate model-types (with up to five constitutive kernel types), which are tested on two standard test problems and an airfoil design problem.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
Final project report on grocery store management system..pdfKamal Acharya
In today’s fast-changing business environment, it’s extremely important to be able to respond to client needs in the most effective and timely manner. If your customers wish to see your business online and have instant access to your products or services.
Online Grocery Store is an e-commerce website, which retails various grocery products. This project allows viewing various products available enables registered users to purchase desired products instantly using Paytm, UPI payment processor (Instant Pay) and also can place order by using Cash on Delivery (Pay Later) option. This project provides an easy access to Administrators and Managers to view orders placed using Pay Later and Instant Pay options.
In order to develop an e-commerce website, a number of Technologies must be studied and understood. These include multi-tiered architecture, server and client-side scripting techniques, implementation technologies, programming language (such as PHP, HTML, CSS, JavaScript) and MySQL relational databases. This is a project with the objective to develop a basic website where a consumer is provided with a shopping cart website and also to know about the technologies used to develop such a website.
This document will discuss each of the underlying technologies to create and implement an e- commerce website.
