Entropy-Aware Position Embedding (EAPE): Prioritizing Discriminative Information
Our EAPE dynamically modulates positional embeddings, acting as a saliency detector. High-entropy (rare) radicals get stronger signals, suppressing low-entropy (ubiquitous) ones, addressing information inequality among radicals. This mechanism is crucial for fine-grained character classification and outperforms standard PEs (Sinusoidal PE, RoPE) by highlighting unique identifiers.
Prioritizes Discriminative Roots
EAPE ensures that rare, information-rich radicals contribute more to character recognition than common, low-entropy components.
Dual-View Radical Tree (DVRT): Capturing Hierarchical Structures
To rigorously capture the hierarchical 2D structures of Chinese characters, we propose the Dual-View Radical Tree (DVRT). It parses IDS into a binary syntax tree and computes embeddings from two distinct perspectives: a Parent-Centric Global View (capturing global layout dependencies from root to node) and a Child-Centric Local View (preserving local compositional details, emphasizing node roles relative to siblings/children). This extracts five distinct encoding vectors, providing a richer structural prior than simple sequences.

Adaptive GateFusion Network: Deep Semantic Alignment
The Adaptive GateFusion Network is a core component of our Multi-Stage Semantic Matching Module. It synthesizes heterogeneous structural information by employing a Sigmoid-based gating mechanism for each of the four structural embeddings (Entropy-Aware Representation, Tree Depth, Global Structural, Local Structural Features). This dynamically modulates feature magnitude and injects the radical content as a bias term, ensuring robust fusion. Unlike shallow metric learning, GateFusion captures complex non-linear correspondences and preserves critical structural cues.

Top-K Semantic Feature Fusion: Enhancing Robustness for Unseen Characters
In Zero-Shot Learning (ZSL), relying solely on the Top-1 nearest semantic vector can be brittle due to subtle structural differences and high-dimensional space complexity. Our Top-K Semantic Feature Fusion strategy addresses this by leveraging the semantic consensus of multiple (Top-K) nearest radical prototypes to construct a robust query for the Transformer decoder. This mitigates noise from outliers and improves fault tolerance.
Robustness through Top-K Semantic Feature Fusion
Scenario: In Zero-Shot Learning (ZSL), relying solely on the Top-1 nearest semantic vector can be brittle due to subtle structural differences and high-dimensional space complexity. Our Top-K Semantic Feature Fusion strategy addresses this by leveraging the semantic consensus of multiple (Top-K) nearest radical prototypes to construct a robust query for the Transformer decoder. This mitigates noise from outliers and improves fault tolerance.
Outcome: Instead of a fragile point-to-point match, the model performs a subspace alignment. By aggregating features from K neighbors (e.g., K=5, which aligns with the average radical sequence length), it effectively reconstructs the correct structural identity even when individual Top-1 matches are ambiguous or incomplete. This 'structural error correction' mechanism enhances robustness against handwriting ambiguities and visual similarities, enabling the model to hallucinate the correct prototype for unseen classes. Example: For the character '曾', Top-K fusion correctly assembles its constituent radicals from neighbors like '普', '曹', and '半', overcoming visual ambiguity.
