EmbeddingHandler

EmbeddingHandler is an abstract base class (abc) to handle batch embeddings. This abstract class lays out the structure and expected methods for any derived class that is to handle batch embeddings.

Overview

EmbeddingHandler provides a structured interface with four abstract methods to be implemented by any derived class. These methods provide a mechanism to get embeddings for a list of symbols, get all the embeddings in a sorted order, process the embeddings for a list of symbols, as well as perform any remaining updates following completion of full batch processing.

Example

As EmbeddingHandler is an abstract base class, it cannot be instantiated directly and doesn’t provide any functionality on its own. The following code sample is a mock example of how a subclass may look like when EmbeddingHandler is extended:

from typing import Any, List
from automata.common.symbol import Symbol
from automata.embedding.embedding_base import EmbeddingHandler

class MyEmbeddingHandler(EmbeddingHandler):
    def get_embeddings(self, symbols: List[Symbol]) -> List[Any]:
        # Implement method to return embeddings for a list of symbols
        pass

    def get_all_ordered_embeddings(self) -> List[Any]:
        # Implement method to return all embeddings in a sorted order
        pass

    def process_embedding(self, symbols: Symbol) -> None:
        # Implement method to process embeddings for a list of symbols
        pass

    def flush(self) -> None:
        # Implement method to perform any remaining updates
        pass

Limitations

The primary limitations of the EmbeddingHandler are tied to specific implementations in derived classes. Since EmbeddingHandler is an abstract base class, it doesn’t pose limitations on its own but it gives a layout to be followed, meaning that the limitations of its implementations are up to the specific subclass.

Follow-up Questions

  • Are there more specific templates or guidelines for each of the abstract methods to be implemented for better consistency across different implementations?

  • Could type hints be provided for the return types of the methods of EmbeddingHandler to enhance usage clarity of the respective methods?

  • How are errors and exceptions handled across derived classes of EmbeddingHandler considering it doesn’t define any error handling procedures in its interface?
