TL;DR: A four-tool learning stack for studying AI and machine learning. Perplexity for researching concepts with citations. Kimi for long-form study and document analysis. Kaggle for hands-on practice with real datasets. PaddlePaddle AI Studio for Chinese-language ML courses and GPU notebooks.
The Learning Stack
| Tool | Learning Role | Key Advantage |
|---|---|---|
| Perplexity | Research and concept exploration | Cited sources — verify what you learn |
| Kimi | Study companion and paper reader | 200K context handles entire textbooks/papers |
| Kaggle | Hands-on practice | Free GPU, real datasets, competitions |
| PaddlePaddle AI Studio | Chinese ML courses and projects | Free GPU, Baidu's ML framework, bilingual |
Workflow: Learning a New ML Concept
Step 1: Research (Perplexity, 15 min)
Start with Perplexity: "Explain transformer attention mechanisms for someone who understands basic neural networks." Perplexity provides an explanation with links to the original paper, blog posts, and video tutorials. Follow the citations to verify and deepen understanding.
Step 2: Deep Dive (Kimi, 30 min)
Upload the original "Attention Is All You Need" paper to Kimi. Ask: "Explain Section 3.2 in simple terms" or "What is the intuition behind multi-head attention?" Kimi's massive context window handles entire papers without losing thread.
Step 3: Practice (Kaggle, 1-2 hours)
Find a relevant Kaggle notebook. Search "transformer from scratch" or join a beginner competition. Fork a notebook, run the code, modify parameters, and see what happens. Learning by doing solidifies concepts.
Step 4: Chinese Resources (PaddlePaddle AI Studio)
For Chinese-speaking learners, PaddlePaddle AI Studio offers excellent structured courses with free GPU access. The community is active, and content covers everything from basic ML to production deployment.
Learning Path Suggestions
- Week 1-2: ML fundamentals — Perplexity for concepts, Kaggle's Intro to ML course
