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.

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.

Here are practical and advanced examples that demonstrate how to use the PredictionInterface class for real-world machine learning applications.

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.

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.

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.

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.

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")

The PredictionInterface class provides a robust, extensible framework for managing AI model predictions. Its modular design ensures compatibility with a variety of machine learning workflows, ranging from real-time predictions to batch processing systems. Developers can easily adapt this framework by integrating validation, persistence, and other advanced features.

The class acts as a consistent and scalable layer that abstracts the complexity of interacting with underlying models. It simplifies the handling of input/output transformations, supports error handling strategies, and ensures prediction workflows remain decoupled from specific model architectures. This separation of concerns allows for greater flexibility when upgrading or swapping models without disrupting downstream services.

Moreover, the PredictionInterface can be extended to support auditing, explainability modules, or integration with monitoring tools, making it ideal for production-grade AI systems that require transparency and accountability. Whether deployed in cloud services, local applications, or edge environments, this framework empowers developers to build responsive, reliable, and maintainable prediction pipelines.
