About Me

Who Am I?

Hi I'm Fatemeh. I am a senior NLP scientist at Pythonic AI.

I have experience with Transformer based pre-trained language models such as BERT, RoBERTa, ELECTRA and etc in different downstream Natural Language Processing (NLP) tasks (Classification, Regression, Summarization, Named Entity Recognition, and Information Retrieval).

I have been in the Computer Science field for more than seven years. In the first five years I was mainly concentrated on software development and after that changed my focus to data science projects. I am a confident, team player, and motivated researcher in my field. I have listed a selected set of my projects here on my personal website.

I have experience with both general, biomedical and financial text domain contexts. Also I am focused on transfer learning, Natural Language Processing (NLP), and deep learning. I am passionate about solving real-world problems with state-of-the-art research in the field.

For the past 6 month I have been learning and working on multi-modality projects.

What I do?

My Work

Projects

Query-focused Extractive Summarization using pre-trained models January 2020 - April 2020

  • Course Project for Natural Language Processing(NLP) Course
  • Team Project (collaboration with a PhD student)
  • Used different scoring functions to extract most important sentences of a document
  • Download Project Report
Abstract: In the process of writing a research paper, researchers often spend a lot of time organizing and summarizing previous work related to the research. To help with this problem, the proposal of this project is to use Query-focused Extractive Summarization algorithms to produce relevant highlights in related research. For this project, the problem of insucient labeled data was solved by using pre-trained models such as BERT and BioBERT to produce accurate representations of words. To measure the validity of the approaches, they were applied to the BioASQ dataset of medical articles and obtained results consistent with each other using Cosine similarity and Euclidean distance, each with several pre-trained models. One of the challenges of this project was that producing the embeddings of a lot of sentences with a pre-trained model is a very time- consuming task, so a scalable tool was developed to eciently compute token embeddings for a variety of pre-trained models.

Classification Of Imbalanced Dataset Using BERT Embeddings May 2019 - Aug 2019

  • Course Project for Deep Learning Course
  • Team Project (collaboration with 2 MCS students)
  • Used BERT embeddings to classify the type of harrasment of each tweet in a imbalanced twitter dataset.
  • Download Project Report
Abstract: Online harassment is becoming prevalent as a specific type of communication on Twitter. Considering the huge amount of user-generated tweets each day, the problem of detecting and possibly limiting these contents automatically in real-time is becoming a fundamental problem. But often real-world datasets are imbalanced, comprising predominantly of “normal” examples and less number of “abnormal” ones which causes the learning algorithm to simply generate a trivial classifier that classifies every example as the majority class. To tackle this problem, we use SMOTE to oversample the embeddings of the minority classes where the embeddings are obtained from the BERT pretrained language model. Finally, we use these oversampled embeddings to train our bi-directional LSTM classifier model to categorize the tweets into four classes: non-harassment, sexual harassment, physical harassment and indirect harassment. Our experiments show that using SMOTE on the top layer representations of BERT significantly improves the F1 score than merely adjusting the class weights.

Visual Analysis Of Harassment Classification In Twitter May 2019 - Aug 2019

  • Course Project for Deep Learning Course
  • Team Project (Collaboration with 2 MCS students)
  • Developed a visualization system using D3 to demonstrate the semantic similarity of words.
  • Download Project Report
  • Although We used the same dataset for this project and the deep learning course, the methogologies and purpose of the projects are completly different.
Abstract: In our project, we develop a Deep Neural Network model to classify the tweets based on four classes: non-harassment, sexual harassment, physical harassment and indirect harassment. We then use Deep SHAP, a unified approach that explains the output of any machine learning model to interpret the predictions of our classifier. We demonstrate the semantic similarity of words in the tweet by visualizing the embeddings in low dimensions using t-SNE. To provide a quick, high level information of the similarities and anomalies between the categories, the final predictions of the model are summarized into different styles of TreeMaps.

Kitchen safety IOT project Dec 2017

  • Senior Project for Undergrad in Shiraz Univerity
  • webserver: Laravel Framework
  • website: CodeIgniter Framework, bootstrap
  • Download Project Report
  • GitHub
Descripiton: This project is designed to assist people who work in the kitchen such as, the kitchens of grand hotels, where the matter of temperature and heat turns out to be essential. They have giant refrigerators, freezers, a huge kitchen, and a couple of storage to be taken care of. To make sure that each section is being in an appropriate situation and the systems are functioning correctly, this project is designed to monitor a system to prevent any damage that might happen to these workers. In this system, a temperature and humidity sensor is located in the kitchen. The information that is being received from the environment will be sent out through a Wi-Fi module to a web server, the web server will store the data. Then users can watch theses information from the project website. This website also makes it available for the user to set a threshold in which the kitchen should not increase or decrease. If any change occurred out of the given threshold, the user will immediately be notified with an email. The history of the kitchen's temperature is also available to view anytime on the website.
