# data_ingestion.py
import pandas as pd
import numpy as np
from kafka import KafkaConsumer
import json

def ingest_data(topic='financial_data', bootstrap_servers=['localhost:9092']):
    consumer = KafkaConsumer(
        topic,
        bootstrap_servers=bootstrap_servers,
        value_deserializer=lambda m: json.loads(m.decode('utf-8')),
        auto_offset_reset='earliest',
        enable_auto_commit=True
    )
    for message in consumer:
        data = message.value
        df = pd.DataFrame(data)
        df = preprocess_data(df)
        yield df

def preprocess_data(df):
    # Handle missing values
    df.fillna(method='ffill', inplace=True)
    # Feature engineering
    df['SMA_50'] = df['Close'].rolling(window=50).mean()
    df['SMA_200'] = df['Close'].rolling(window=200).mean()
    df['RSI'] = compute_rsi(df['Close'])
    # Drop rows with NaN values after rolling computations
    df.dropna(inplace=True)
    return df

def compute_rsi(series, period=14):
    delta = series.diff()
    gain = (delta.where(delta > 0, 0)).rolling(window=period).mean()
    loss = (-delta.where(delta < 0, 0)).rolling(window=period).mean()
    rs = gain / loss
    rsi = 100 - (100 / (1 + rs))
    return rsi

Operational Characteristics

Monitoring and Metrics

Continuous monitoring ensures the AI system operates efficiently and maintains high accuracy. Key metrics such as prediction accuracy, processing latency, resource utilization, and trading signal performance are tracked in real-time to identify and address potential bottlenecks.

# metrics_collector.py
import time
import logging

class MetricsCollector:
    def __init__(self):
        self.predictions = 0
        self.correct_predictions = 0
        self.total_latency = 0.0  # in milliseconds
        logging.basicConfig(level=logging.INFO)
    
    def record_prediction(self, is_correct, latency):
        self.predictions += 1
        if is_correct:
            self.correct_predictions += 1
        self.total_latency += latency
    
    def report(self):
        accuracy = (self.correct_predictions / self.predictions) * 100 if self.predictions else 0
        avg_latency = self.total_latency / self.predictions if self.predictions else 0
        logging.info(f"Total Predictions: {self.predictions}")
        logging.info(f"Accuracy: {accuracy:.2f}%")
        logging.info(f"Average Latency: {avg_latency:.2f} ms")

Failure Recovery

The AI system incorporates robust failure recovery mechanisms to ensure uninterrupted operations and data integrity:

  • Automated Retries: Implements retry logic for transient failures during data ingestion and prediction.
  • Checkpointing: Saves intermediate states to allow recovery from failures without data loss.
  • Scalable Redundancy: Utilizes redundant processing nodes to maintain performance during component failures.
  • Health Monitoring: Continuously monitors system health and alerts administrators to potential issues proactively.
# failure_recovery.py
import time
import logging

def robust_predict(model, data, retries=3, delay=5):
    for attempt in range(retries):
        try:
            prediction = model.predict(data)
            return prediction
        except Exception as e:
            logging.error(f"Prediction failed on attempt {attempt+1}: {e}")
            time.sleep(delay)
    raise Exception("Prediction failed after multiple attempts.")
