 ## Improving the Model
 
+### Single-Label Classification
+
 There's a couple things we could do to make this system a little bit more robust.
 
+### Multi-Label Classification
+
+Notice in the example we use Iterable[Tag] vs Tag. This is because we might want to use a multiclass classification model that returns multiple tag!
+
+### Working with DataFrames
+
+When working with large datasets, you might want to use pandas DataFrames for efficient processing. See our [DataFrame Integration Guide](pandas_df.md) for details.
+
+### Streaming Responses
+
+For real-time processing needs, you can utilize streaming responses. Check out our [Partial Streaming Guide](partial_streaming.md) for implementation details.
