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.
- Read and make notes from at least 100 scientific papers or books.
- Publish at least 2 conference papers.
- Prepare for minimal thesis.
Resources:
- [Hate Speech Project Page](/topics/hatespeech)
- https://hatespeechdata.com/
- [Hate speech detection: Challenges and solutions](https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6701757/)
- [HateBase](https://hatebase.org/)

## 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
## 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:
- Try [this model](https://huggingface.co/cardiffnlp/twitter-roberta-base-sentiment) with your own text.
- Learn how Transformers Neural Network Works. Learn how Roberta Model training works. Learn how BERT model finetuning works. Write a short memo about your findings and papers read on this topic.
- Pick a dataset:
- https://huggingface.co/datasets/sentiment140 (english)
- https://www.clarin.si/repository/xmlui/handle/11356/1054 (multilingua)
- https://huggingface.co/datasets/tamilmixsentiment (english tamil code switch)
- Grab baseline BERT type model and try to finetune it for sentiment classification.
- For finetuning and evaluation you can use this scrip https://github.com/huggingface/transformers/tree/master/examples/pytorch/text-classification
- For finetuning you will need to install CUDA and Pytorch. It can work on CPU or NOT.
- If you need GPU, use the school server idoc.fei.tuke.sk or google Colab.
- Continue working on the paper.
- Remind me about the SCYR conference payment.
## 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.
- [x] 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.
