Abstract:
Position encoding in transformers provides sequence sense for input tokens.
New proposals like Rotary Position Embedding (RoPE) aim to improve position encoding.
Geotokens represent specific geological locations, emphasizing coordinates over order.
Introduction:
Transformer model is efficient for natural language tasks due to self-attention mechanism.
RoPE offers a new perspective on positional data incorporation into transformers.
Notion of Geotokens and Geotransformers:
Encoding geographical entities holds promise for various fields beyond text processing.
Transformers can handle spatial data efficiently due to their parallel processing capabilities.
Original Position Encoding Mechanism:
Method suggested for encoding sequential positions in the initial transformer architecture has been effective.
Rotary Position Encoding (RoPE):
RoPE uses a rotation matrix to capture relative position information within self-attention process.
Spherical Position Encoding:
Adapting RoPE technique for spherical coordinates is essential for representing global positions accurately.
Experimental Results:
Proposed spherical position embedding significantly improves training losses compared to random encoding.
Conclusion:
Incorporating geotokens in transformer architectures enhances cognition of geospatial concepts.
