Data Science Portfolio

End to End Projects

  • Utilized Python programming language and Bash scripting to preprocess and extract features from 4D complex brain imaging data amounting to 0.25 TB, applying a 3D multiresolution optical flow technique.
  • Employed signal processing techniques with Python programming language to modulate respiratory signals with calculated brain signal speed.
  • Conducted A/B testing to identify significant differences in the modulation of brain cardiovascular pulse with respiration between control subjects and individuals with Alzheimer's disease.
  • Visualized and presented research findings to neurological researchers, contributing to a greater understanding of Alzheimer's disease. Additionally, authored and submitted a paper to JCBFM.
  • Paper: Elabasy, A., Suhonen, M., Rajna, Z. et al. Respiratory brain impulse propagation in focal epilepsy. Sci Rep 13, 5222 (2023). https://doi.org/10.1038/s41598-023-32271-7
  • Trained multiple classifier that improved the classification performance of imbalanced Alzheimer’s fMRI images by more than 12% compared to state of art on the same data.
  • Analyzed, visualized, and discussed the results with a team of neurological researchers to have a better understanding of the results and Alzheimer’s disease.
  • Analyzed, visualized, and reported the results and submitted a research paper to ISPr 2023 scientific conference.
  • Developed a real-time sign language interpretation application using React.js, tensroflow and tensorflow.js and deployed on IBM cloud servies.
  • Building a stable diffusion web application using Hugging Face, React, and deployed on fastAPI.
  • Building a recommendation engine using Alternating Least Squares in PySpark and using the popular MovieLens dataset and the Million Songs dataset.
  • Building a real time car plate detection mobile application using Tensorflow and EasyOCR.

Skill Based Projects

Machine Learning:

Regression

  • Automobile price prediction: Utlitize python to implement end to end data science pipeline to predict the price of old Automobile based on the given features.

Classification

  • Sensor Activity Recogniation: Classifying the output of eight sensors into five activities and studied the effect of changing window sizes and axel combination.
  • Alzhimers CV-BOLD Classification: Utilized Python to develop supervised machine learning techniques to classify imbalanced Alzheimer’s CVBOLD data, which enhanced the classification performance by 10%.
