Hugo's AI Journey
- Hugo Larochelle's AI journey began with an early interest in AI, leading him to Joshua Bengio's lab.
- He worked on neural networks during their unpopular phase and contributed to the deep learning surge.
Transfer Learning
- Transfer learning encompasses pre-training and fine-tuning, but other methods exist.
- Fine-tuning is a simple but potentially suboptimal approach with drawbacks like high memory and compute costs.
Fine-Tuning vs. Probing
- The research landscape includes fine-tuning, linear probing, and methods in between.
- Fine-tuning specific parameters, like biases, offers a compromise between performance and efficiency.
