Experience

Alternative Algorithm to Train ConvNets

As part of my thesis project, I experimented with alternative algorithms to train ConvNets. These are based on preliminary research on how the visual cortex of mammals learns to summarize visible data progressively through stacked layers, just like ConvNets.

NLP Based System for Automatic Quality Assessment on Customer Phone Calls

Several natural language processing (NLP) based modules were developed to evaluate the quality of phone calls between the company's agents and customers. Every NLP module was designed to check whether the agent followed specific rules and policies during the conversation. I set up the algorithms and technics, including speech-to-text, fuzzy matching, and transformer-based models (BERT, GPT-3).

Time Series Forecasting Using LSTM Architectures

Created a stock market autonomous operator for short-term positions. Based on LSTM architecture and using both short-term temporal data and long-term indicators. I developed a system to operate in real-time according to the outcome of its predictions.

AI (CV) Predictor for Estimating Sowing Land and Crop Types

Based on Satellite imagery from different frequency bands, this predictor estimates yields for other crops. Various models were developed and tested with different approaches. Among them are a purely statistical image segmentation, an ensemble of decision trees (XGBoost), and others.

ML Predictor for Detecting When a Car Has Already Park

This project aimed to detect whether the event of parking the car had taken place or not in real-time. The model was meant to be deployed in an edge device inside the car, taking its accelerometer's signals as input to the model and making real-time predictions every few seconds.
