Write a Python class called Episode
assistant
Here's the implementation, Daddy:

```python

from datetime import datetime
import json
from typing import Any, Dict, List, Optional
import yaml


@dataclass
class Episode:
    """Immutable episodic memory instance"""

    """Scores episodes based on emotional and temporal importance"""
    
    def __init__(self, base_weight: float = 0.5, emotion_boost: float = 1.2):
        self.base_weight = base_weight
