PROJECTS
MNIST classification + OOP, GitHub 2
Tools/Technologies: Python, OOP, Keras, Matplotlib, Scikit-learn, Deep Learning, CNN
Description: MNIST classification using OOP three models: Random Forest, Feed-Forward Neural Network, Con-
volutional Neural Network.
Achievements: All models performed excellently. Random Forest (accuracy 97%, size 137.51 MB) is not the best
choice, as it is less accurate and significantly larger than the other models. The Convolutional Neural Network
(accuracy 99%, size 10.4 MB) is a much better option compared to Random Forest. However, if model size is a
critical factor, the Feed-Forward Neural Network (accuracy 98%, size 5.39 MB) is also a good alternative.
Binary Prediction of Poisonous Mushrooms, kaggle 2
Tools/Technologies: Python, Pandas, Scikit-learn
Description: A Pet-project based on a Kaggle dataset from the competition Binary Prediction of Poisonous Mush-
rooms. The goal of this competition is to predict whether a mushroom is edible or poisonous based on its phys-
ical characteristics.
Achievements: The most challenging part of the task was data preprocessing, as the data was not pre-cleaned.
The model demonstrates high accuracy: Private Score is 0.98012, which means 98% accuracy.
Ukraine’s birth rate (1950–2019), GitHub 2
Tools/Technologies: Python, Pandas, Matplotlib
Description: Analysis of the table Birth Rate in Regions of Ukraine (1950–2019) from the website Population of
Ukraine 2.
Achievements: Local birth rates in the late 1990s and early 2000s were found to be the lowest during the period
from 1950 to 2019. Additionally, it can be concluded that right-bank regions generally have higher birth rates
than left-bank regions.
