The aim of the study is to study a simplex mixture of three raw materials and characterize it in terms of price, viscosities and stabilities at different conditions. Due to a difficulty in postulating an a priori model and a possible area of instability of the formulas which could compromise the plan and the subsequent analysis of the results (no measurable response in the event of instability), a plan Space-Filling type with excluded zone is carried out. A first modeling with different Machine Learning type models (SVM, Gaussian Process) is carried out, but certain areas of the experimental space are poorly represented due to missing values for viscosity (too low viscosity or instability of some formulations). Using information from business expertise, and the choice of imputation of local values by K-Nearest Neighbors, the modeling can be corrected and provide satisfactory results, providing a better representation and understanding of the formula space .

Biography Passionate about data science and chemistry, my goal is to combine business expertise, experimental designs and data analysis to help laboratories leverage their historical data, effectively plan their next experiments, make better decisions and to unravel some of the mysteries of chemistry. Rational and data-driven, I am ready to share my passion and help make data literacy accessible to everyone. Curious, I love reading and learning about innovations, technology, science, chemistry, statistics, data science and analytics. Area of interest: Innovation, Digitalization, Design of Experiments, Statistics, Machine Learning, Data Analysis, Data Visualization and Chemoinformatics.
