Episode notes
Diagram Lost To Proprietary Format
- The host recounts a story where a Visio diagram became inaccessible after the software was discontinued.
- This personal example highlights risks of proprietary formats causing long-term data loss.
Export Diagrams To Open Formats
- Export important diagrams to open formats like SVG or PDF regularly to ensure future access.
- Adopt open standards or routine exports to guard against vendor obsolescence.
Two-Stage Fine-Tuning Reduces Overfitting
- A two-stage fine-tuning approach keeps broad language ability while specializing for tasks.
- Separating general unsupervised pretraining from targeted fine-tuning reduces overfitting on small datasets.
