Redis AI Challenge: Real-Time AI Innovators

This is a submission for the Redis AI Challenge: Real-Time AI Innovators

What I Built

NeuralFlow Optimizer - An intelligent, real-time neural network performance optimization system that uses Redis 8 as a multi-dimensional data engine to accelerate AI model training and inference through dynamic feature streaming, semantic caching, and vector-based performance prediction.

🎯 Core Innovation

The system combines three powerful Redis 8 capabilities:

Vector Search for similarity-based model architecture optimization
Semantic Caching for intelligent computation reuse across training epochs
Real-time Streams for continuous performance metric analysis and dynamic hyperparameter adjustment

🚀 Key Features

Intelligent Hyperparameter Optimization: Uses Redis vector search to find similar training configurations and predict optimal parameters
Semantic Computation Cache: Caches intermediate neural network computations based on semantic similarity, reducing training time by 40-60%
Real-time Performance Analytics: Streams training metrics to Redis for instant visualization and anomaly detection
Dynamic Model Scaling: Automatically adjusts model complexity based on real-time performance patterns
Cross-Model Knowledge Transfer: Leverages Redis's multi-model capabilities to share learned optimizations across different neural architectures

How I Used Redis 8

1. Vector Search for Model Optimization 🎯

# Store model architectures as vectors for similarity search
redis_client.hset(
    "model:arch:123",
    mapping={
        "layers": json.dumps([64, 128, 256, 128, 64]),
        "activation": "relu",
        "optimizer": "adam",
        "performance_vector": vector_embedding.tobytes()
    }
)

# Find similar high-performing architectures
similar_models = redis_client.ft("model_index").search(
    Query("*=>[KNN 5 @performance_vector $vec AS score]")
    .sort_by("score")
    .paging(0, 5)
    .dialect(2),
    query_params={"vec": current_model_vector.tobytes()}
)

2. Semantic Caching for Computation Reuse 🧠

# Semantic cache for neural network layer computations
def get_semantic_cache_key(layer_weights, input_shape, activation):
    # Create semantic fingerprint of computation
    semantic_vector = create_semantic_embedding(layer_weights, input_shape, activation)

    # Search for similar computations in Redis
    similar_computations = redis_client.ft("computation_cache").search(
        Query("*=>[KNN 1 @semantic_vector $vec AS similarity]")
        .filter("@similarity < 0.1")  # High similarity threshold
        .return_fields("result", "similarity"),
        query_params={"vec": semantic_vector.tobytes()}
    )

    if similar_computations.docs:
        cache_hits.increment()
        return pickle.loads(similar_computations.docs[0].result)

    return None

# Cache computation results with semantic indexing
def cache_computation_result(weights, input_shape, activation, result):
    semantic_vector = create_semantic_embedding(weights, input_shape, activation)
    cache_key = f"computation:{uuid.uuid4()}"

    redis_client.hset(cache_key, mapping={
        "semantic_vector": semantic_vector.tobytes(),
        "result": pickle.dumps(result),
        "timestamp": time.time(),
        "input_shape": json.dumps(input_shape),
        "activation": activation
    })

3. Real-time Performance Streaming 📊

# Stream training metrics in real-time
class TrainingMetricsStreamer:
    def __init__(self, redis_client, model_id):
        self.redis = redis_client
        self.stream_key = f"training:metrics:{model_id}"

    def log_epoch_metrics(self, epoch, loss, accuracy, lr, grad_norm):
        self.redis.xadd(self.stream_key, {
            "epoch": epoch,
            "loss": loss,
            "accuracy": accuracy,
            "learning_rate": lr,
            "gradient_norm": grad_norm,
            "timestamp": time.time()
        })

    def detect_anomalies(self):
        # Real-time anomaly detection using Redis streams
        recent_metrics = self.redis.xrevrange(self.stream_key, count=10)

        # Analyze patterns and trigger alerts
        losses = [float(metric[1][b'loss']) for metric in recent_metrics]
        if self.is_gradient_explosion(losses):
            self.trigger_learning_rate_adjustment()

# Consumer for real-time dashboard updates
def stream_consumer():
    while True:
        messages = redis_client.xread({
            "training:metrics:*": "$"
        }, block=1000)

        for stream, msgs in messages:
            for msg_id, fields in msgs:
                # Update real-time dashboard
                websocket.broadcast(format_metrics(fields))

4. Dynamic Hyperparameter Optimization 🔄

# Use Redis TimeSeries for hyperparameter optimization
class HyperparameterOptimizer:
    def __init__(self, redis_client):
        self.redis = redis_client

    def update_performance_history(self, config_vector, performance_score):
        # Store in Redis TimeSeries for trend analysis
        config_hash = hashlib.sha256(config_vector.tobytes()).hexdigest()[:16]
        self.redis.ts().add(f"perf:{config_hash}", int(time.time()), performance_score)

        # Vector search for similar configurations
        self.redis.hset(f"config:{config_hash}", mapping={
            "vector": config_vector.tobytes(),
            "performance": performance_score,
            "timestamp": time.time()
        })

    def suggest_next_configuration(self, current_performance):
        # Find top-performing similar configurations
        current_vector = self.encode_current_config()

        similar_configs = self.redis.ft("config_index").search(
            Query("*=>[KNN 10 @vector $vec AS score]")
            .sort_by("performance", asc=False)
            .return_fields("vector", "performance", "score"),
            query_params={"vec": current_vector.tobytes()}
        )

        # Genetic algorithm-style optimization using Redis data
        return self.evolve_configuration(similar_configs)
