Abstract
This study presents a hybrid machine learning
model that enhances indoor localization accuracy by
combining Neural Networks, Decision Trees, Support Vector
Regression, and Gradient Boosting Regressor. Accurate
indoor positioning is a critical challenge due to the
unreliability of Global Positioning System signals in enclosed
spaces. Wireless Fidelity based positioning has emerged as a
practical alternative, leveraging existing access points to
estimate locations without additional infrastructure. Two
main use cases for such an application are guiding guests
through a building and tracking the movement of individuals,
such as student attendance in a university or employees in a
company. The model's performance is evaluated using key
metrics such Mean Absolute Error, Mean Squared Error,
Root Mean Squared Error, and R² score, along with
classification-based evaluation and learning curve analysis to
assess generalization and training efficiency. Experimental
results show that the hybrid approach outperforms individual
models by leveraging their strengths, leading to improved
positioning precision. These findings demonstrate the
potential of machine learning-driven indoor localization and
pave the way for more accurate and efficient positioning
technologies.
