||||
✓ Uses `SimpleEmbedder` from `api_clients`
|
||||
✓ Uses `SemanticVector` from `ruvector_native`
|
||||
✓ Uses `FrameworkError` and `Result<T>`
|
||||
✓ Rate limiting with `tokio::sleep`
|
||||
✓ Retry logic with exponential backoff
|
||||
✓ Comprehensive documentation comments
|
||||
✓ Example code in doc comments
|
||||
|
||||

## Usage Example
|
||||
|
||||
```rust
|
||||
use ruvector_data_framework::{
|
||||
HuggingFaceClient, OllamaClient, PapersWithCodeClient,
|
||||
NativeDiscoveryEngine, NativeEngineConfig
|
||||
};
|
||||
|
||||
#[tokio::main]
|
||||
async fn main() -> Result<(), Box<dyn std::error::Error>> {
|
||||
// Create clients
|
||||
let hf = HuggingFaceClient::new();
|
||||
let mut ollama = OllamaClient::new();
|
||||
let pwc = PapersWithCodeClient::new();
|
||||
|
||||
// Collect ML models
|
||||
let models = hf.search_models("transformer", None).await?;
|
||||
let vectors: Vec<_> = models.iter()
|
||||
.map(|m| hf.model_to_vector(m))
|
||||
.collect();
|
||||
|
||||
// Collect research papers
|
||||
let papers = pwc.search_papers("attention").await?;
|
||||
let paper_vectors: Vec<_> = papers.iter()
|
||||
.map(|p| pwc.paper_to_vector(p))
|
||||
.collect();
|
||||
|
||||
// Generate embeddings with Ollama
|
||||
let text = "Neural networks for NLP";
|
||||
let embedding = ollama.embeddings("llama2", text).await?;
|
||||
|
||||
// Run discovery
|
||||
let mut engine = NativeDiscoveryEngine::new(NativeEngineConfig::default());
|
||||
for v in vectors.into_iter().chain(paper_vectors) {
|
||||
engine.ingest_vector(v)?;
|
||||
}
|
||||
|
||||
let patterns = engine.detect_patterns()?;
|
||||
println!("Discovered {} patterns", patterns.len());
|
||||
|
||||
Ok(())
|
||||
}
|
||||
```
|
||||
|
||||
## Testing
|
||||
|
||||
```bash
|
||||
# Run all tests
|
||||
cargo test ml_clients
|
||||
|
||||
# Run specific tests
|
||||
cargo test test_huggingface
|
||||
cargo test test_ollama
|
||||
cargo test test_replicate
|
||||
|
||||
# Run with output
|
||||
cargo test ml_clients -- --nocapture
|
||||
|
||||
# Run ignored integration tests (requires API keys)
|
||||
cargo test ml_clients -- --ignored
|
||||
```
|
||||
|
||||
## Environment Setup
|
||||
|
||||
```bash
|
||||
# Optional: HuggingFace (public models work without key)
|
||||
export HUGGINGFACE_API_KEY="hf_..."
|
||||
|
||||
# Optional: Replicate (falls back to mock)
|
||||
export REPLICATE_API_TOKEN="r8_..."
|
||||
|
||||
# Optional: Together AI (falls back to mock)
|
||||
export TOGETHER_API_KEY="..."
|
||||
|
||||
# For Ollama: start service
|
||||
ollama serve
|
||||
ollama pull llama2
|
||||
```
|
||||
|
||||
## Next Steps
|
||||
|
||||
### Recommended Enhancements
|
||||
1. Add streaming support for chat/generation
|
||||
2. Implement batch operations for efficiency
|
||||
3. Add caching layer for repeated queries
|
||||
4. Extend to more ML platforms (Anthropic, Cohere, etc.)
|
||||
5. Add embeddings similarity search
|
||||
6. Implement model comparison features
|
||||
|
||||
### Integration Ideas
|
||||
1. Build ML model discovery pipeline
|
||||
2. Cross-reference papers with implementations
|
||||
3. Track model evolution over time
|
||||
4. Discover emerging ML techniques
|
||||
5. Find related datasets for models
|
||||
