// Abstract
In this MLOps Meetup, we talked about the Machine Learning model lifecycle and development stages, and then analyzed the main mistakes that everybody makes at each stage. Kseniia also provided the audience with solutions to the mistakes, and we discussed existing tools for experiment management.

// Bio
Kseniia is a product owner for Data/AI-based products. Right now, she is working mostly with numeric data analysis, customer insights, and product recommendations.
Previously, Kseniia worked at Samsung Research with the biometrics team. She was studying computer science in Russia (Moscow) and a little bit of management in South Korea (Seoul). One of the most interesting directions of research - Model Lifecycle Management Systems and Reproducibility.

[03:40] AI Development Process: Common Mistakes
[07:45] Step 1: Planning
[07:48] Mistake #1: Personal Decisions - Teamwork
[08:31] Mistake #1: Cases
[09:00] Mistake #1: Solution
[11:52] Scrum
[12:50] "In Scrum, it's hard to plan because, especially in research, you don't know which result affects new tasks; that's why it might be a little slow for Machine Learning."
[14:28] Step 2: Data Processing
[14:34] Mistake #2: Chaos with Datasets
[15:26] Mistake #2: Cases
[16:48] Mistake #2: Solution
[20:12] Step 3: Experiments
[20:21] Mistake #3: Lack of Experiment Tracking
[22:13] Mistake #3: Case - Manual Experiments Tracking
[24:10] Mistake #3: Solutions
[25:57] Experiments Tracking Tools Example: MLFlow UI
[26:46] Awareness of Existing Tools
[28:21] Tools' Features
[29:21] Possible Combination
[29:48] Another Possible Combination
[30:24] Best Practice
[34:18] Find Your Mistakes  
[35:35] Audio Data
[41:38] "I prefer reproducibility tools because it's automatic, and it also takes a lot of time to manually upload the results into the conference."
[43:03] AI Development Check-list
[43:40] Check-list Results
[44:52] "I think it's always interesting to rate yourself to share the results with other people to compete out of it."
[45:10] Why to Implement
[45:17] "If we have more automation on experimentations for data sets versioning, it will lead to less manual work."
[45:28] "AI Development process implementation will have the possibility to reproduce and compare experiments."
[45:37] "AI Development process implementation will make you comfortable with solving the issues you'll face every day."
[45:52] "AI Development process implementation will lead to a faster commercialization cycle because you will take less time on the process and more time for the results."
[46:03] "If we take all the principles of the AI Development process implementation, it will lead to easy communication between team members. You'll gain trust, have great teamwork, and everyone will have respect for each other."
