The pith
YOLOv11 Nano reaches 46.6% mAP@50 and 3.2% higher precision than YOLOv8 Nano on fused driving data in rain and low light.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
YOLOv11n achieves a mean Average Precision (mAP@50) of 46.6% with a 3.2% improvement in Precision over YOLOv8n on the custom fused dataset of dense mixed traffic under rain and low-light conditions, while requiring 22% fewer FLOPs (6.3G versus 8.1G) at a real-time speed of 70.9 FPS on a Tesla T4 GPU.
What carries the argument
Direct comparison of YOLOv11 Nano and YOLOv8 Nano architectures on the fused IDD plus BDD100K dataset for detection under adverse weather.
Load-bearing premise
The measured gains come from architectural differences in YOLOv11 rather than from how the two models were trained or how the source datasets were combined and balanced.
What would settle it
Retrain both YOLOv11n and YOLOv8n from identical random initializations on the exact same fused dataset split using the same augmentation and optimization schedule, then check whether the 3.2% precision and 22% FLOP gaps persist.
read the original abstract
In modern vehicular systems, robust performance under harsh conditions has become a critical problem of autonomous driving. Our study delivers a comprehensive evaluation of the newest iteration of the YOLO series, which is YOLOv11 Nano architecture benchmarked against the widely adopted YOLOv8 Nano as a baseline on a custom fused dataset that combines the Indian Driving Dataset (IDD) [1] and Berkeley Deep Drive Dataset (BDD100K) [2]. We have analyzed the trade-offs among detection accuracy, inference speed, and computational efficiency in high-entropy scenarios involving dense mixed traffic, rain, and low-light conditions. Specifically, YOLOv11n achieves a mean Average Precision (mAP@50) of 46.6%, with a notable 3.2% improvement in Precision over the baseline, effectively reducing false positives in cluttered scenes. Furthermore, the proposed model exhibits enhanced energy efficiency, requiring 22% fewer FLOPs (6.3G vs. 8.1G) while maintaining real-time inference speed of 70.9 FPS on a Tesla T4 GPU, offering an optimal trade-off for safety-critical edge deployment.

Referee Report
Summary. The manuscript evaluates YOLOv11 Nano against YOLOv8 Nano on a fused IDD+BDD100K dataset for object detection in dense mixed traffic under rain and low-light conditions typical of developing countries. It claims YOLOv11n delivers 46.6% mAP@50, a 3.2% precision gain over the baseline (reducing false positives), 22% fewer FLOPs (6.3G vs. 8.1G), and 70.9 FPS on a Tesla T4 GPU, positioning it as an efficient choice for safety-critical edge deployment.
Significance. If the numeric gains are shown to result from architectural differences under controlled identical training conditions and are reproducible, the work would supply useful empirical guidance for selecting lightweight detectors suited to resource-limited autonomous-driving scenarios in high-entropy traffic environments. The emphasis on adverse weather and developing-country datasets addresses a practically relevant gap, though current unverifiability restricts immediate adoption.
major comments (2)
- [Abstract] Abstract: The reported performance deltas (46.6% mAP@50, 3.2% precision lift, 22% FLOP reduction) are presented as direct outcomes of YOLOv11n versus YOLOv8n, yet no information is supplied on training protocol, loss functions, hyperparameter search, optimizer settings, learning-rate schedules, data-augmentation pipelines, or the exact fusion and class-balancing procedure applied to IDD+BDD100K. This omission renders the central attribution of gains to architecture unverifiable.
- [Experimental setup] Experimental setup (throughout manuscript): No statement confirms that both models received identical training schedules, augmentation, or balancing weights during dataset fusion. Without this control, the observed differences cannot be isolated from potential confounding variables, directly undermining the claim that YOLOv11n provides an "optimal trade-off" due to its design.
Simulated Author's Rebuttal
We thank the referee for the constructive comments regarding the need for detailed experimental information. We will revise the manuscript to provide comprehensive details on training protocols and explicitly confirm identical conditions for both models.

Referee: [Abstract] Abstract: The reported performance deltas (46.6% mAP@50, 3.2% precision lift, 22% FLOP reduction) are presented as direct outcomes of YOLOv11n versus YOLOv8n, yet no information is supplied on training protocol, loss functions, hyperparameter search, optimizer settings, learning-rate schedules, data-augmentation pipelines, or the exact fusion and class-balancing procedure applied to IDD+BDD100K. This omission renders the central attribution of gains to architecture unverifiable.
Authors: We agree that the manuscript currently lacks explicit details on the training protocol, hyperparameters, loss functions, optimizer settings, learning-rate schedules, data-augmentation pipelines, and the fusion/class-balancing procedure for IDD+BDD100K. In the revised version, we will add a dedicated subsection in the Experimental Setup section that fully documents these elements, including the exact values and procedures used. This addition will allow verification that performance differences arise under controlled, identical conditions. revision: yes

Authors: We acknowledge that the current text does not explicitly confirm identical training conditions for YOLOv11n and YOLOv8n. The revised manuscript will include a clear statement in the Experimental Setup section affirming that both models were trained with the same schedules, augmentations, and balancing weights. We will also provide the specific hyperparameter values and procedures to isolate architectural effects. revision: yes
Circularity Check
No circularity: direct empirical benchmarking with no derivations or self-referential reductions
full rationale
The paper is a straightforward empirical comparison of YOLOv11n vs YOLOv8n on a fused IDD+BDD100K dataset under adverse conditions. It reports measured metrics (mAP@50 = 46.6%, precision lift of 3.2%, FLOPs 6.3G vs 8.1G, 70.9 FPS) as experimental outcomes without any equations, fitted parameters, predictions derived from inputs, or load-bearing self-citations. Dataset citations [1][2] are external and non-overlapping. No step reduces by construction to the paper's own inputs; the central claims remain falsifiable measurements.
