🧠 Adaptive Reasoning Bridge

A state-of-the-art reasoning controller for Large Language Models featuring entropy-based adaptive scaling and iterative budget forcing

Features • Installation • Quick Start • Documentation • Examples • Contributing

📖 Overview

Adaptive Reasoning Bridge is a cutting-edge inference controller that enhances LLM reasoning capabilities through dynamic, entropy-guided computation allocation. By intelligently detecting uncertainty in model outputs and adaptively scaling reasoning depth, it bridges the gap between computational efficiency and reasoning quality.

from adaptive_bridge import AdaptiveReasoningBridge

# Initialize the controller
bridge = AdaptiveReasoningBridge(
    model_name="deepseek-ai/DeepSeek-R1-Distill-Qwen-7B",
    tp_size=1,  # Tensor parallel size
    entropy_threshold=1.35  # Uncertainty threshold
)

max_new_tokens (int): Max tokens per generation step
temperature (float): Sampling temperature for diversity
top_p (float): Nucleus sampling parameter

Returns:

Parameters:

query (str): User query
max_tokens (int): Maximum tokens to generate

Entropy Calculation

The controller uses Shannon entropy to measure uncertainty:

H = -Σ(p(x) × log(p(x)))

Sectional Analysis Weights:

Introduction: 20% (setup and context)
Body: 60% (core reasoning)
Conclusion: 20% (synthesis)

Decision Logic:

weighted_entropy = 0.2×H₁ + 0.6×H₂ + 0.2×H₃

if weighted_entropy > threshold:
    trigger_additional_reasoning()

💡 Examples

Example 1: Mathematical Reasoning

from adaptive_bridge import AdaptiveReasoningBridge

bridge = AdaptiveReasoningBridge(
    model_name="deepseek-ai/DeepSeek-R1-Distill-Qwen-7B",
    entropy_threshold=1.35
)

query = """
A train leaves Station A at 2:00 PM traveling at 60 mph toward Station B.
Another train leaves Station B at 2:30 PM traveling at 80 mph toward Station A.
The stations are 350 miles apart. At what time will the trains meet?
"""

result = bridge.generate_intellect(
    query=query,
    budget_limit=3,
    max_new_tokens=2048
)

# Output includes step-by-step reasoning and final answer

Example 2: Logic Puzzles

query = """
In a room, there are 3 light switches. Each controls one of three light bulbs 
in another room. You cannot see the bulbs from the switch room. You can flip 
the switches as many times as you want, but can only enter the bulb room once. 
How can you determine which switch controls which bulb?
"""

result = bridge.generate_intellect(query=query, budget_limit=2)
print(f"Solution:\n{result['answer']}")

Example 3: Code Analysis

# Lower entropy threshold for technical tasks
bridge = AdaptiveReasoningBridge(
    model_name="deepseek-ai/DeepSeek-R1-Distill-Qwen-7B",
    entropy_threshold=1.2
)

query = """

def bubble_sort(arr):
    n = len(arr)
    for i in range(n):
        for j in range(0, n-i-1):
            if arr[j] > arr[j+1]:
                arr[j], arr[j+1] = arr[j+1], arr[j]
    return arr

queries = [
    "What is the capital of France?",
    "Explain quantum entanglement",
    "Write a Python function to find prime numbers"
]

results = []
for query in queries:
    result = bridge.generate_intellect(query, budget_limit=2)
    results.append(result)

# Save results
with open('batch_results.json', 'w') as f:
    json.dump(results, f, indent=2)

# Fine-tuned configuration for specific use cases
bridge = AdaptiveReasoningBridge(
    model_name="your-model-name",
    tp_size=2,                    # Use 2 GPUs
    entropy_threshold=1.5,        # Higher threshold (less sensitive)
    max_context_length=16384      # Smaller context window
)

result = bridge.generate_intellect(
    query="Your query here",
    budget_limit=5,               # Allow up to 5 iterations
    max_new_tokens=1024,          # Shorter generations
    temperature=0.6,              # More focused sampling
