Manohar Gowdru Shridhara

Beginning of the study: 2021

repository: https://git.kemt.fei.tuke.sk/mg240ia

Disertation Thesis

in 2023/24

Hate Speech Detection

Goals:

  • Write a dissertaion thesis
  • Publish 2 A-class journal papers

Minimal Thesis

(preliminary dissertaion and exam in 2022/23)

Goals:

  • Provide state-of-the-art overview.
  • Formulate dissertation theses (describe scientific contribution of the thesis).
  • Prepare to reach the scientific contribution.
  • Publish 4 conference papers.

First year of PhD study

Goals:

  • Provide state-of-the-art overview.

  • Publish at least 2 conference papers.
  • Prepare for minimal thesis.

Resources:

Meeting 24.5.

  • shared colab notebook, with on-going implementation of mayfly algorithm for preprocessing in sentiment recogniution in a twitter dataset.

Tasks:

  • Implement open tasks from the previous meetings !!!
  • Focus on making a baseline experiment for sentiment classification using classcal methods, such as Transformers.
  • Consider using pre-trained embeddings. FastText, word2vec, sentence-transformers, Labse, Laser,

Supplemental tasks:

  • Fininsh the mayfly implementation

Meeting 20.5.

  • learned about Firefly / mayfly optimization algorithm.
  • read ten papers,
  • wrote 1 page abstract about possible system, based od DBN.

Meeting 25.4.

  • Learned aboud deep learning lifecycle / evaluation, BERT, RoBERTa, GPT
  • Tried HF transformers, Spacy, NLTK, word embeddings, sentence transformers.
  • Set up a repo with notes: https://git.kemt.fei.tuke.sk/mg240ia

Tasks:

  • Publish experiments into the repository.
  • Prepare a paper for publication in faculty proceedings http://eei.fei.tuke.sk/#!/
  • Send me draft in advance.

Suplemental tasks:

  • For presentation of the results, learn about https://wandb.ai/. This can dispplay results (learning curve, etc.)
  • For preparing a web aplication with demo, learn about streamlit.

Meeting 12.4.

  • Created repositories, empty so far.
  • Tried to replicate the results from "Emotion and sentiment analysis of tweets using BERT" paper and "Fine-Tuning BERT Based Approach for Multi-Class Sentiment Analysis on Twitter Emotion Data".
  • The experiments are based on BERT (which kind?), Tweet Emotion Intensity.
  • Prepared colab notebook with experiments.

Tasks:

  • Finish experiments, upload source codes into git, provide a description of the experiments.
  • Try to improve the results - try different kind of BERT - roberta, electra, xl-net. Can "generative models" be used? (gpt, bart, t5). Can "sentence transformers be used" - labse, laser.
  • Learn about "Sentence Transformers".
  • Summarize the results in the table, publish the table on git.
  • [-] Use Markdown for formatting. There is "Typora".
  • [-] Continue to improve the SCYR paper.
  • If you have some conference in mind, tell me.

Meeting 25.3.22

  • Learned about Transformers, BERT, LSTM and RNN.
  • Tried HuggingFace transformers library
  • Started Google Colab - executing sentiment analysis, hf transformers pipeline functions.
  • prepared datasets: twitter-roberta Datasets. Experiments a re riunnig, no results yet.
  • prepared a short note about nlp and neural networks.
  • still working on the SCYR paper

Tasks:

  • [-] finish experiments about sentiment and present results.
  • [-] create a repository on git.kemt.fei.tuke.sk and upload your experiments, results and notes. Use you student creadentials.
  • [-] continue working on "SCYR" review paper, consider publishing it elswhere (the firs version got rejected).
  • [-] prepare an outline for another paper with sentiment classification.

Meeting 10.3.22

  • Improvement of the report.
  • Installed Transformers and Anaconda

Tasks:

Meeting 21.2.22

  • Written a report about HS detection (in progress)

Tasks:

  • Repair the report (rewrite copied parts, make the paragrapsh be logically ordered, teoreticaly - formaly define the HS detection, analyze te datasets in detail - how do they work. what metric do they use).
  • Install Hugging Face Transformers and come through a tutorial

Meeting 31.1.22

  • Read some blogs about transformers
  • Installed and tied transformers
  • Worked on the review paper
  • Picked the Twitter Dataset on keggle
  • still selecting a method

Open tasks:

  • Continue to work on the paper and share the paper with us.
  • Prepare som ideas for the common discussion about the project.
  • Try to prepare an experiment with the selected dataset.
  • You can use the school CUDA infrastructre (idoc.fei.tuke.sk).
  • Set up a repository for experiments, use the school git server git.kemt.fei.tuke.sk.
  • Get ready to post a paper on the school PhD conference SCYR, deadline is in the middle of February http://scyr.kpi.fei.tuke.sk/.

Meeting 10.1.22

  • Set up a git account https://github.com/ManoGS with script to prepare "twitter" dataset and "english" dataset for HS detection.
  • confgured laptop with (Anaconda) / PyCharm, pytorch, cuda gone throug some basic python tutorials.
  • Read some blogs how to use kaggle (dataset database).
  • tutorials on huggingface transformers - understanding sentiment analysis.

Open tasks:

  • Continue to work on the review - with datasets and methods (specified below).

No report (just draft) was provided so far.

  1. Read papers from below and make notes what you have learned fro the papers. For each note make a bibliographic citation. Write down authors of the paper, name paper of the paper, year, publisher and other important information. When you find out something, make a reference with a number to that paper. You can use a bibliografic manager software. Mendeley, Endnote, Jabref.

Meeting 10.11.21

First tasks

Prepare a report where you will explain:

  • what is hate speech detection,
  • where and why you can use hate-speech detection,
  • what are state-of-the-art methods for hate speech detection,
  • how can you evaluate a hate-speech detection system,
  • what datasets for hate-speech detection are available,

The report should properly cite scientific bibliographical sources. Use a bibliography manager software, such as Mendeley.

Create a VPN connection to the university network to have access to the scientific databses. Use scientific indexes to discover literature:

Your review can start with:

Get to know the Python programming language
