Make Some Noise (MSN) Framework

Implementation of EMNLP 2024 paper Make Some Noise: Unlocking Language Model Parallel Inference Capability through Noisy Training. [Github]

Requirements

Environment: We adopt the same environment as used in Spec-Bench to facilitate a fair and consistent evaluation.
Prepared Models: For convenience of testing, we release the weights of both the general-purpose model [Llama3-8B-MSN] and the code-specific model [DeepSeek-Coder-7B-MSN] trained on MSN as discussed in the paper.

A minimal implementation of MSN

The MSN framework can be easily integrated into the data preprocessing stage of any training script. The entire noise addition process is as follows:

python

# L denotes the noise length hyperparameter, which is typically set to 5.
dataset = [
    {"source_ids": "Query prompt.",
    "input_ids": "Concatenation of the query and response.",
    "output_ids": "Copy of input_ids as label for LM task."}
]
for source_ids, input_ids in dataset:
    start_idx = random.randrange(len(source_ids), len(input_ids)-L)
    for mask_i in range(start_idx, start_idx+L):
        # Noise is added only to the input portion corresponding to the response.
        input_ids[mask_i] = random.choice(input_ids[:mask_i])

TR-Jacobi

We demonstrate how to use TR-Jacobi to accelerate the MSN-trained model in src/inference_msn.py.

python

# jacobi decoding
spec_res_ids, new_tokens, forward_steps, accpet_list = noise_forward(input_ids.cuda(), model, tokenizer, args.max_new_tokens)

print("msn output")
print(tokenizer.decode(spec_res_ids[0]))
print("#MTA")
print(new_tokens/forward_steps)
print("Accepted Length List")
print(accpet_list)

Run sh run_case.sh to obtain the execution process of a test sample. The interface design of the entire noise_forward is kept consistent with Spec-Bench.
