Work Experience

SEDSR&D

CERN

Intern, Software Engineering and Data Analysis

I worked at CERN for three months, at the CMS Experiment lab, working specifically on the 'CMS-GEM' collaboration, which involved changing particle detector’s technology to Gas Electron Multiplier (GEMs).

  • Refined efficiency of production code by implementing requested features on Python scripts.
  • Improved code used for testing detector in a QC stand by adding an step-size feature.
  • Created method for configuring detector’s electrical state with custom values.
  • Published real time gas levels of a mixer by writing code to send data to a server via an API.

Facial Information Extraction

MSc, Computer Vision, Convolutional Neural Networks
  • Attempted to use state-of-the-art deep learning techniques to build models which take an image as input.
  • Performed facial detection, recognition, and emotion classification on the present individuals on the images.
  • Achieved 95% test accuracy on facial recognition with convolutional neural networks and hyper-parameter tuning.
  • Built separate models for tasks such as emotion classification before combining them into an end-to-end models.
  • Optimised performance with DL best practices: data augmentation, batch-normalisation, cross-validation.

Deep Reinforcement Learning: Flappy Bird

Deep Q-Learning Network, Deep Deterministic Policy Gradient, Experience Replay

Attempted to a develop model which is able to learn to play Flappy Bird, and surpass human level scores by using Reinforcement Learning techniques. Specifically investigated Deep Q-Learning networks to develop an overview of the problem and deeper understanding on reinforcement learning techniques. Wished to showcase how computer vision and deep neural networks such as convolutional neural networks can be used in the context of reinforcement learning as well.

Kaggle Competition: Toxic Comment Classification

Multi-Label Classification Problem

Attempted to solve a Kaggle competition in a group of three to the best of our abilities. Specifically strove for implementations beyond the exsiting classical ones, and attempted to develop a model which is well-adapted and fine tuned to the specific problem at hand. Implemented a Naive-Bayes Bag of Words model, Random Forest, Extra Trees, and compared their results with the Log Regression, Convolutional Neural Network, and Long Short-Term Memory Recurrent models.

MLBayesianStats

Bayesian Machine Learning

Hamiltonian Monte Carlo Stochastic Methods, Automatic Relevance Determination

Used Bayesian modelling methods, specifically Hamiltonian Monte Carlo, to approximate Gaussian posterior distributions on a multivariate regression task to derive a good predictor from the dataset, and estimate which of the input variabels are relevant for prediction.

Open Information Extraction

Speech Tagging, Named Entity Recognition, Relation Extraction, Kitchen Sink

Attempted to summarise Jules Verne's 20,000 leagues under the seas' by training a classifier that indicates which of the part of speech tags each word is. The approach was based on Identifying Relations for Open Information Extraction (Fader, Soderland & Etzioni). To this end, Glove word vectors were employed to implement a logistic one vs all kitchen sink model, and attempted speech tagging on word and sentence levels, named entity resolution and relation extraction.

Robotics I

Localisation, Pathfinding, Navigation, Calibration, Object Detection

Wrote a program using the Java LeJOS framework that enables a robot to explore the arena which contains a small number of obstacles, placed at random locations. There was a single coloured sheet of paper which the robots had to be able to detect using the colour sensor which also signifed the end location, to which the robot had optimally navigate back to the ending position.

Robotics II

Scout, Doctor, Agents, Jason

Wrote a program using the Java LeJOS framework allowing a robot to determine it's starting location in the arena, and optimally work its way to the pre-determined ending position using scout and doctor agents while avoiding the possible obstacles.

Android Food App

Full stack development

Scran is a user-oriented application that aids in the decision-making process when choosing a restaurant, and more specifically a dish. Scran will maintain, search and track user and restaurant data to help its users to choose the dish they didn’t know they wanted.

Moving Average Filter

Generate, Filter and Display data

Wrote C++ in Xcode to generate random plot and noise values of a sinusoidal function using signal characteristics as parameters, which would then be handled by the designed event driven panels and data structures in LabVIEW, and subsequently transferred to Matlab to be displayed in both filtered and unfiltered states.

iOS Revision App

Developed iOS app with first generation Swift on xCode.

  • Goal was to give students a platform to revise and prepare for exams on the go.
  • Content specifically tailored to the common first-year Bachelor course.
  • Option of adding content for additional modules and courses by users.
  • Hopefully improve the student pass rate at EPFL by providing feedback and tips.

FULL Student feature: My summer Internship at CERN

"Arriving wide-eyed at the main lab on the first day, I discovered that I was among twenty other excited students, from all over the world, ranging from Thailand, Brazil, France, US, India, Italy and many others, all of whom had arrived at different moments during the summer, meaning there was little time for individual introductions to the lab and explanations of the various hardware components and the software code base."
