AI Interface Prediction
* More Developers Docs: The PredictionInterface class provides a simple yet powerful abstraction for handling predictions in machine learning systems. This module serves as the interface between external input and the prediction mechanism of an AI model. It is a critical component for AI systems designed to provide real-time insights or batch outputs based on user input or datasets.

Class Overview
```python import logging
class PredictionInterface:
""" Manages the interface for making model predictions. """
def __init__(self, model):
"""
Initializes the PredictionInterface with a machine learning model.
:param model: The AI/ML model responsible for generating predictions.
"""
self.model = model
def handle_prediction_request(self, input_data):
"""
Handles incoming prediction requests and returns responses.
:param input_data: Data to predict on
:return: Prediction result from the model
"""
logging.info("Handling prediction request...")
# Placeholder prediction logic
predictions = [x * 2 for x in input_data] # Mock predictions
logging.info(f"Predictions: {predictions}")
return predictions
```
Core Attributes: - `model`: The AI model instance responsible for generating predictions. - `handle_prediction_request(input_data)`: Method that handles input data, generates predictions, and logs activity.

Modular Workflow
1. Initialize Interface with Model:
Pass any compatible machine learning model instance to the `PredictionInterface` during initialization.
2. Handle Prediction Requests:
Use the `handle_prediction_request()` method to process incoming data and retrieve prediction results.
3. Extend for Functionality:
Add input pre-processing, output post-processing, or advanced error handling as required.

Usage Examples
Here are practical and advanced examples that demonstrate how to use the PredictionInterface class for real-world machine learning applications.
—
Example 1: Basic Mock Prediction
This example demonstrates using the `PredictionInterface` with placeholder logic for mock prediction.
```python from ai_interface_prediction import PredictionInterface
# Mock model (placeholder for an actual ML model) mock_model = None
# Initialize the PredictionInterface interface = PredictionInterface(mock_model)
# Input data for prediction input_data = [1, 2, 3, 4, 5]
# Perform prediction predictions = interface.handle_prediction_request(input_data) print(“Predictions:”, predictions)
# Output: # INFO:root:Handling prediction request… # INFO:root:Predictions: [2, 4, 6, 8, 10] # Predictions: [2, 4, 6, 8, 10] ```
Explanation: - Uses the mock prediction logic (`x * 2`) as a placeholder for real AI model predictions. - Logs the prediction process for traceability.
—
Example 2: Integrating with a Pre-Trained Model
Extend the interface by incorporating an actual machine learning model, such as a scikit-learn or TensorFlow model.
```python from sklearn.linear_model import LinearRegression import numpy as np
# Define a simple linear regression model and train it model = LinearRegression() X = np.array(1], [2], [3], [4], [5) # Features y = np.array([2, 4, 6, 8, 10]) # Target values model.fit(X, y)
# Integrate the model with the PredictionInterface interface = PredictionInterface(model)
# Prediction input data input_data = np.array(6], [7], [8)
# Perform prediction using the trained model predictions = interface.handle_prediction_request(input_data) print(“Predictions:”, predictions) ```
Explanation: - Replaces the placeholder logic with real predictions from a trained scikit-learn `LinearRegression` model. - Adapts for advanced scenarios with actual models.
—
Example 3: Adding Input Validation
This example adds validation to ensure input data integrity.
```python class ValidatingPredictionInterface(PredictionInterface):
""" Extends the PredictionInterface to validate input data. """
def handle_prediction_request(self, input_data):
# Validate input data
if not isinstance(input_data, list) or not all(isinstance(x, (int, float)) for x in input_data):
raise ValueError("Input data must be a list of numeric values.")
# Call the parent method
return super().handle_prediction_request(input_data)
# Usage interface = ValidatingPredictionInterface(None)
try:
predictions = interface.handle_prediction_request([1, 2, 'three', 4]) # Contains invalid data
except ValueError as e:
print(e) # Output: Input data must be a list of numeric values.
```
Explanation: - Ensures only numeric data is passed to the prediction process, preventing invalid inputs.
—
Example 4: Batch Predictions with Logging
This example improves the interface by introducing batch processing.
```python class BatchPredictionInterface(PredictionInterface):
""" Extends the PredictionInterface to handle batch prediction requests. """
def batch_predictions(self, input_batches):
"""
Handles batch prediction requests.
:param input_batches: A list of input data batches
:return: A list of predictions for all batches
"""
all_predictions = []
for batch in input_batches:
logging.info(f"Processing batch: {batch}")
all_predictions.append(self.handle_prediction_request(batch))
return all_predictions
# Usage interface = BatchPredictionInterface(None) batch_data = 1, 2, 3], [4, 5, 6], [7, 8, 9
# Perform batch predictions batch_results = interface.batch_predictions(batch_data) print(“Batch Predictions:”, batch_results)
# Logs: # INFO:root:Processing batch: [1, 2, 3] # INFO:root:Processing batch: [4, 5, 6] # INFO:root:Processing batch: [7, 8, 9] ```
Explanation: - Designed for scenarios requiring predictions over multiple datasets in a single operation.

Example 5: Persistent Prediction Results
Save prediction results to a file for further analysis.
```python import json
class PersistentPredictionInterface(PredictionInterface):
""" Extends PredictionInterface to save predictions to a file. """
def save_predictions(self, predictions, filename="predictions.json"):
"""
Save predictions to a JSON file.
:param predictions: List of predictions
:param filename: Output file name
"""
with open(filename, 'w') as file:
json.dump(predictions, file)
logging.info(f"Predictions saved to {filename}.")
# Usage interface = PersistentPredictionInterface(None) predictions = interface.handle_prediction_request([1, 2, 3]) interface.save_predictions(predictions, “predictions.json”) ```
Explanation: - Ensures prediction results can be stored and loaded later by saving them in a JSON file.
