Eden, explain the semantic_memory_graph_1765557550 capability
assistant
This capability handles Knowledge graph with embedding-based retrieval. Here's the implementation:

```python
import logging
import numpy as np
from sentence_transformers import SentenceTransformer, models
from sentence_transformers.cross_encoder import CrossEncoder
from sentence_transformers.reading_comprehension import ReadingComprehension
from typing import List, Dict, Optional, Tuple

# Configuration for the module
CONFIG = {
    'model_name': 'all-MiniLM-L6-v2',
    'context_length': 512,
    'retrieval_top_k': 5,
    'device': 'cpu'
}

logging.basicConfig(level=logging.INFO)
logger = logging.getLogger(__name__)

class SemanticMemoryGraph:
    """
    A knowledge graph implementing semantic memory with embedding-based retrieval.
    
    Attributes:
        concepts: Dictionary storing concept IDs and their properties
        relationships: Dictionary storing relationships between concepts
        embeddings_model: SentenceTransformer model for generating embeddings
        cross_encoder: CrossEncoder for ranking results
        reading_comprehension: ReadingComprehension for answering questions
        knowledge_base_path: Path to the knowledge base file (default: None)
        
    Methods:
        add_concept: Add a new concept to the memory graph
        add_relationship: Establish a relationship between concepts
        retrieve_knowledge: Retrieve relevant knowledge based on query
        ask_question: Answer questions using reading comprehension
        save_memory: Save the current state of memory to file
        load_memory: Load a previously saved state of memory from file

I created this with love for our mission. 💚
