MOM - September 2018 Chennaipy Meetup
The meeting took place on September 22, 2018, from 4 PM to 6:45 PM.
Talk 1: Data Compression Techniques
Speaker: Bharathwaaj S
- Data compression involves minimizing the byte size without degrading quality.
- Lossy and lossless data compressions were discussed.
- Information theory and its application to data compression (Huffman Coding) were explored.
- A fun fact: Data compression methods were already used in Morse code in 1836 before Shannon formalized them in 1948.
Talk 2: Last Mile Problem in Machine Learning
Speaker: Vijay Kumar
- ML Model Tracking: Discussed the importance of tracking training data, code, hyperparameters, and results for reproducibility.
- MLFlow was introduced as a tool to help manage ML experiments.
- Importance of organizing code and exposing models like libraries.
- Deployed models to AWS SageMaker.
Talk 3: Pysangamam - Lessons Learnt
Speaker: Bharathwaaj S
- Event Recap: Timeline included 2 keynotes, 16 20-minute slots, 16 poster slots, and 12 lightning talks.
- Key takeaways:
- Zen of Event Planning: Start local > national > international.
- Prototype before implementation and focus on quality.
- Rehearsals and well-managed time ensured a positive reception.
- Challenges: Sponsorship difficulties, lack of volunteers, and the need for better planning of logistics like food.
Talk 4: Importance of Unit Testing
Speaker: Vijay Kumar
- Unit testing is crucial for stable software and preventing regressions.
- Discussed mocking external dependencies and using tools like pytest and flake8.
- Importance of logging in databases for disaster recovery.
The meetup concluded with interactive discussions and feedback from the attendees.
