In this project, I've worked on a solution to predict which of the nine-floor types the robot is using sensor data to help it improve navigation.
I help companies to leverage Machine Learning to create innovative products through an end-to-end machine learning development process that designs, builds, and manages reproducible, testable, scalable, and evolvable ML-powered software with minimal cost.

Machine Learning Operations is a process of automating and productionalizing machine learning applications and workflows.
In this project, I've built a Computer Vision model to find basket icons in e-commerces.
This project was part of a Kaggle competition promoted by Data Science Academy in September of 2019.
The goal of the competition was to create a Machine Learning model to help a robot to classify the floor surface on which it is using data collected by Inertial Measurement Units (IMU) sensors.
About the project
The data used in this competition was collected by the Tampere University Signal Processing Department in Finland. Data collection was performed with a small mobile robot equipped with IMU sensors on different floor surfaces at the university premises. The task is to predict which of the nine floor types (carpet, tiles, concrete, etc.) the robot is using sensor data such as acceleration and velocity. The success of this competition will help improve the navigation of autonomous robots on many different surfaces.

A small mobile robot equipped with IMU sensors needs to know the current floor surface it is to improve the navigation.
Predict which of the nine-floor types (carpet, tiles, concrete, etc.) the robot is using sensor data such as acceleration and velocity.
Build a Machine Learning model that based on the data send by IMU sensors can classify the current floor surface.
I've used Python to perform an Exploratory Data Analysis (EDA) using visual and quantitative methods to understand and summarize the data. Then I've performed Data Cleaning and built several Machine Learning models to classify the current floor surface based on sensor data.
The final model was a Stacking of LightGBM, Random Forest, and Extra Trees with the Logistic Regression model as a meta classifier. The evaluation metric for this competition was the Multiclass Accuracy, which is simply the average rating number with the correct label.
In this competition, my best score was 62.2% and I've got position 26 on the leaderboard.
The University that promote this competition may use these results to improve the navigation of autonomous robots on many different surfaces.
I've written a blog post with details about this project.
The solution is also available at Github.
