[Finetune]Finetuning deep learning model using LoRA technique via Pytorch and PEFT to build a boilerplate filtering model, increase performance by 10x.[LLM Clustering]Design a LLM Clustering Procedure.

Taipei–Keelung Metropolitan Area

[Large Language Model]Make use of LLM to develop an AI Summary feature on Quid Discover Product. - Extensive use of modern LLM tools like Langchain, Langsmith, OpenAI api, and Promptfoo. - Design a sampling algorithm to do representative documents sampling. - Construct the backend API and playground.[Time Series Forecasting]Implement forecasting feature to Trend Detection module. - Survey SOTA paper and find out the best combination of models by experiment. - Pretrain DL forecasting model on our data to boost performance.[Image Captioning]Develop an Image Network POC on Quid Discover Product and Won the first place in our company competition. - Create an end-to-end workflow in a week. Utilize state-of-the-art image captioning method.[Experiment Design]Apply Statistical Methods like ANOVA and Pairwise comparison to verify a better Clustering Algorithm and find out significant best settings all in once and make production code change.[Module Algorithm/Engineering Improvement]Improve Trend Detection and Created a website page for users to play with. The new algorithm is used by Coke, Hershey, and Novartis. - Change to more appropriate statistical tests and introduce new technique in trend scoring. - Apply multi-process and code-refactoring.[Algorithm/ Code Structure Design]Improve Keyword Display Quality for all Dataset - Display Hashtag in names/keywords without interfering the core process. Invent ngram represent notion. - Use lemma as candidates to avoid problems of same word appearing in panel with different forms. Select most frequent token as each ngram's representation. - Avoid unigram contained in multi-gram being displayed solely. Design count filtering logic to achieve the goal.

[Time Series Analysis] [Statistical Analysis]- Invent a Trend Detection methodology from scratch. Currently used by Coca Cola and Novartis. This innovative method has brought in over 100k+ USD profit.[Machine Learning] [Natural Language Processing]The fixed version has been praised by PMs and Sales. They did not need to revise names manually anymore.- Find out systematic flaws of our Cluster Naming algorithm. - Change selection condition to enable unigram as candidates, and apply multigram inclusion technique to make names more meaningful. - Apply part of speech filter. - Design specific input for different dataset based on their characteristic.[Algorithm Design]- Make Ethnicity Distribution Estimation account for minorities to a large extent. The accuracy rate increases over 50% on minorities topics and can better reflect actual Social Media User Distribution.- Improve Algorithm of Generating Representative Words of a cluster by finding a balance between recall and precision.[Experiment]- Design a thorough 3-stage plan to compare performance between tokenizers. Two of the three stages' methods are completely innovative.[Research]- Research on entity embedding methods for related word engine[Guidance]- Prepare an Onboarding PPT for new Data Scientist including Company Tech Stack, Commonly Used Tools, and Benefit. It is then used by other colleagues to introduce our company to new comers.
