Praise be to Allah, the lord for all worlds, and may peace and blessings be upon His Messenger, Muhammad (peace be upon him) .  \nIt is with immense gratitude and humble commitment that I present this work, “Virtual measurement in wastewater treatment plant: Machine learning models for predicting the PO4 concentration in the effluent”, as part of my master ‘s thesis. This has been a journey of learning, discovery, and growth, and I acknowledge the blessings and guidance from Allah the Almighty throughout this project.  \nThe aim of this master’s thesis is to develop a comprehensive machine learning algorithms for effluent quality control for HIAS wastewater treatment plant. The study includes various machine learning algorithms. The aim is to assess effectiveness of these models in accurately predicting effluent parameter values and classifying effluent quality based on time-series historical dataset, from HIAS wastewater treatment plant. The work involves data preprocessing, model training, evaluation and validation through evaluation metrics.  \nI would like to express my sincere appreciation to my supervisors, Arvind Keprate, Abhilash Nair and Tiina Komulainen, for their scholarly expertise and constant support. Their insightful feedback, and continuous support, and patient mentoring have been instrumental in shaping this work. I would also like to offer my sincere thanks to the members of my thesis group for their expertise, time, and valuable assistance in evaluating and reviewing this work. Their suggestions and constructive comments have greatly developed the quality of the research.  \nFurthermore, I would like to express my deep gratitude to my family and friends for their support. Especially my parents, where their unwavering encouragement , love and understanding throughout this academic journey. Their moral support and prayers were a source of motivation for me. Thanks for believing in me.  \nFinally, I acknowledge that this work would not have been possible without the guidance and blessing from Allah the Almighty. I am grateful for the knowledge granted to me. May this work serve as a means of seeking knowledge, benefitting humanity, and earning the pleasure of Allah, the most High.  \nTable of Contents  \nTable of Contents ........................................................................................................................................3  \nList of Figures ..............................................................................................................................................4  \nList of Tables................................................................................................................................................ 5  \n1 INTRODUCTION ........................................................................................................................................8  \n1.1 General .................................................................................................................................................8  \n1.2 Process description ...............................................................................................................................9  \n2 State of the Art ....................................................................................................................................... 10  \n3 Theoretical background .......................................................................................................................... 15  \n3.1 Supervised learning ..............................................","cbCaifav8fBL8rjK","https://ap.wps.com/l/cbCaifav8fBL8rjK","pdf",2450648,1,71,"English","en",105,"# Introduction\n## General\n## Process description\n# State of the Art\n# Theoretical background\n## Supervised learning\n## Cubic Spline Interpolation\n## Pearson correlation coefficient\n## Evaluation Metrics\n# Methodology and Materials\n## Data analytics for WWTP\n## Data preparation\n## Data Preprocessing","[{\"question\":\"What is the main goal of the thesis?\",\"answer\":\"To develop machine learning algorithms that accurately predict effluent PO4 concentration and classify effluent quality for the HIAS wastewater treatment plant.\"},{\"question\":\"Which kind of data is used for training and evaluation?\",\"answer\":\"A time-series historical dataset collected from the HIAS wastewater treatment plant is used for model training and validation.\"},{\"question\":\"What steps are included in building the models?\",\"answer\":\"The workflow covers data preprocessing and preparation, model training, and evaluation/validation using defined evaluation metrics.\"}]","Virtual measurements in wastewater treatment plant -
