Large Action Models represent an evolution in AI architecture, combining transformer-based language understanding with action execution capabilities through a neuro-symbolic framework that lets you direct interaction with external systems and APIs while maintaining contextual awareness of tasks and constraints.

Let’s make this super clear! Here’s how we can tackle this:

from typing import Dict, List, Any

class LAMProcessor:
    def __init__(self, action_space: Dict[str, Any]):
        self.action_space = action_space
        self.action_history = []
        
    def process_task(self, user_input: str) -> Dict[str, Any]:
        # Parse user intent and map to action space
        task_embedding = self._embed_task(user_input)
        action_sequence = self._plan_actions(task_embedding)
        return self._execute_actions(action_sequence)
        
    def _embed_task(self, task: str) -> np.ndarray:
        # Convert task description to vector representation
        return np.random.randn(768)  # Simplified embedding
        
    def _plan_actions(self, embedding: np.ndarray) -> List[str]:
        # Generate sequence of atomic actions
        return ['authenticate', 'search', 'validate', 'execute']

# Example usage
action_space = {

🚀 Results Analysis for Task Learning Module - Made Simple!

Here’s where it gets exciting! Here’s how we can tackle this:

# Example execution results
test_sequence = [
    {'action': 'open_email', 'params': {'client': 'outlook'}},
    {'action': 'compose', 'params': {'to': 'test@example.com'}},
    {'action': 'attach_file', 'params': {'path': 'report.pdf'}},
    {'action': 'send_email', 'params': {}}
]

learner = TaskLearningModule(input_dim=512, hidden_dim=768)
learner.learn_from_observation(test_sequence)

# Generated workflow results
generated_workflow = learner.generate_workflow({
    'context': 'email_composition',
    'frequency': 'daily'
})

print("Generated Workflow Steps:")
for step in generated_workflow:
    print(f"Action: {step['action']}")
    print(f"Parameters: {step['params']}")
    print("Confidence Score:", step.get('confidence', 0.0))
    print("---")

# Example output:
# Generated Workflow Steps:
# Action: open_email
# Parameters: {'client': 'outlook'}
# Confidence Score: 0.92
# ---
# Action: compose
# Parameters: {'to': 'test@example.com'}
# Confidence Score: 0.88
# ---
# Action: attach_file
# Parameters: {'path': 'report.pdf'}
# Confidence Score: 0.85
# ---
# Action: send_email
# Parameters: {}
# Confidence Score: 0.94

🚀 Integration with External Systems - Made Simple!

The system builds a reliable integration layer that manages connections with external APIs, databases, and services while maintaining security protocols and handling rate limiting, authentication, and data transformation.

This next part is really neat! Here’s how we can tackle this:

from abc import ABC, abstractmethod
import aiohttp
import jwt
from typing import Dict, Any, Optional

class ExternalSystemConnector(ABC):
    def __init__(self, config: Dict[str, Any]):
        self.config = config
        self.session = None
        self.rate_limiter = TokenBucketRateLimiter(
            rate=config.get('rate_limit', 100),
            bucket_size=config.get('bucket_size', 10)
        )
        
    async def initialize(self):
        self.session = aiohttp.ClientSession(
            headers=self._get_auth_headers()
        )
        
    async def execute_request(self, 
                            method: str, 
                            endpoint: str, 
                            data: Optional[Dict] = None) -> Dict:
        await self.rate_limiter.acquire()
        
        async with self.session.request(
            method, 
            f"{self.config['base_url']}{endpoint}",
            json=data
        ) as response:
            response.raise_for_status()
            return await response.json()
            
    def _get_auth_headers(self) -> Dict[str, str]:
        token = jwt.encode(
            {
                'sub': self.config['client_id'],
                'exp': datetime.utcnow() + timedelta(hours=1)
            },
            self.config['client_secret'],
            algorithm='HS256'
        )
        return {'Authorization': f"Bearer {token}"}
        
    @abstractmethod
    async def transform_data(self, 
                           data: Dict[str, Any]) -> Dict[str, Any]:
        pass
