参数

1. qa_form

• Purpose: Defines the form of generated QAs.

• Options:

  • "atomic": Simple, single-node QAs.

  • "multi_hop": Multi-step reasoning QAs.

  • "aggregated": QAs that require analyzing and integrating multiple entities and relationships.

• Default: "multi_hop"

2. expand_method

• Purpose: Controls traversal limits.

• Options:

  • "max_width": Limits by edge count (max_extra_edges).

  • "max_tokens": Limits by token count (max_tokens).

• Default: "max_tokens"

3. bidirectional

• Purpose: Enables traversal in both directions.

• Type: bool

• Default: True

4. max_extra_edges

• Purpose: Max edges per direction (if expand_method="max_width").

• Type: int

• Default: 5

5. max_tokens

• Purpose: Restricts input length (if expand_method="max_tokens").

• Type: int

• Default: 256

6. max_depth

• Purpose: Limits traversal depth per direction.

• Type: int

• Default: 2

• Example: A → B → C for max_depth=2.

7. edge_sampling

• Purpose: Selects edges at the same traversal level.

• Options:

  • "max_loss": Prioritizes high-loss edges.

  • "min_loss": Prioritizes low-loss edges.

  • "random": Random selection.

• Default: "max_loss"

8. isolated_node_strategy

• Purpose: Manages nodes with no connections.

• Options:

  • "add": Includes isolated nodes.

  • "ignore": Skips them.

• Default: "add"

9. loss_strategy

• Purpose: Defines loss computation focus.

• Options:

  • "only_edge": Loss for edges only.

  • "both": Loss for nodes and edges.

• Default: "only_edge"
