ALBERT vs SLICK: MARSAIL’s New AI Fashion for Real-Time Car Insurance
Balancing Cutting-Edge Accuracy with Lightning-Fast Speed in Automotive AI

ALBERT vs SLICK: The New AI Fashion at MARSAIL
In the fast-evolving world of automotive insurance, precision and speed are absolutely critical. Enter MARSAIL (Motor AI Recognition Solution Artificial Intelligence Laboratory), Thailand’s pioneering hub of automotive AI innovation. In 2025, MARSAIL proudly unveils two revolutionary models that are reshaping how car damage is detected, analyzed, and processed for insurance claims — ALBERT and SLICK.
These models represent more than just technological progress; they embody a new philosophy in AI-powered insurance: a seamless synergy between uncompromising accuracy and lightning-fast efficiency, inspired by the teacher-student paradigm.
At the core of this paradigm lies ALBERT, the “teacher” — a powerhouse model meticulously engineered for razor-sharp precision. ALBERT dives deep into images, discerning the finest scratches, dents, and cracks with near-human expertise. It’s a master of detail, leaving no nuance unseen, perfect for complex offline investigations and comprehensive damage evaluations where absolute accuracy is essential.
Yet, speed is just as critical in today’s insurance ecosystem, especially for frontline claim processing and on-site damage assessments. This is where SLICK, the “student,” steps in. Trained and guided by ALBERT’s expert knowledge, SLICK is designed to be nimble, agile, and incredibly fast — capable of delivering reliable damage detection results instantly on edge devices or even mobile phones. Its streamlined architecture empowers insurance agents and repair shops to operate smarter and faster without compromising quality.
Together, ALBERT and SLICK form a powerful duo that bridges the traditional divide between accuracy and efficiency — offering the best of both worlds to revolutionize car insurance workflows across Thailand and beyond.
ALBERT: The Teacher Model — Precision at a Cost
ALBERT stands for Advanced Localization and Bidirectional Encoder Representations from Transformers. This model is designed to be highly accurate and detailed in detecting subtle damages such as small scratches, dents, and cracks on vehicles. It leverages a vision transformer architecture enhanced with localized deformable tokens and parameter sharing to precisely focus on critical damage regions.
However, this precision comes with a computational cost. ALBERT requires powerful CUDA-enabled GPUs and is relatively slow, making it ideal for offline batch processing or scenarios where accuracy takes precedence over speed.

SLICK: The Student Model — Lightning Speed Meets Smart Knowledge
To address real-time insurance needs, MARSAIL developed SLICK — Selective Localization and Instance Calibration with Knowledge. This model distills knowledge from ALBERT and integrates domain-specific insurance metadata like bumper zones and vehicle model weak points.
SLICK boosts processing speed by over 700% compared to ALBERT, enabling instant damage assessments on edge devices or mobile apps without sacrificing much accuracy. Its adaptive attention mechanism dynamically calibrates segmentation proposals using contextual knowledge graphs, making it robust under varying light, weather, and occlusion conditions.

🚘 Teaching machines to see smarter and faster: the MARSAIL teacher-student model
In the race to deliver the best car damage detection for insurance claims, MARSAIL takes a cutting-edge approach inspired by how humans learn: through mentorship. Our teacher-student model architecture pairs a high-capacity “teacher” network with a lean, speedy “student” model, capturing the best of both worlds — precision and efficiency.

What is the teacher-student model?
Think of the teacher as a seasoned expert with a deep understanding of vehicle damage nuances — it’s large, powerful, and painstakingly precise. The student, meanwhile, is like an apprentice: smaller, faster, and designed to perform well in real-world settings with limited resources.
The magic happens when the student learns to mimic the teacher’s insights without needing to replicate its full complexity. This process is known as knowledge distillation — where the teacher’s “soft” predictions guide the student’s training, helping it grasp subtle visual patterns that would be hard to learn from raw data alone.

Measuring size and efficiency: teacher vs. student
To illustrate the trade-off, here’s a glimpse of the teacher and student model sizes trained on the CIFAR-10 dataset. The teacher is notably larger but more precise, while the student’s compact size enables rapid inference — crucial for insurance agents working on the go.

How does the student learn from the teacher?
The training process involves the student observing both the teacher’s output and the ground truth, gradually adjusting itself to replicate the teacher’s nuanced judgments. This dual supervision accelerates the student’s learning curve, enabling it to deliver near-teacher accuracy with significantly fewer parameters.

Results that speak volumes
On multiple datasets and architectures (including CNN and ResNet), MARSAIL’s teacher-student training methods consistently improved student model accuracy across the board — sometimes by over 3% compared to training without guidance.
Model | Dataset | No KD (%) | BLKD (%) | TAKD (%) |
---|---|---|---|---|
CNN | CIFAR-10 | 70.16 | 72.57 | 73.51 |
CNN | CIFAR-100 | 41.09 | 44.57 | 44.92 |
ResNet | CIFAR-10 | 88.52 | 88.65 | 88.98 |
ResNet | CIFAR-100 | 61.37 | 61.41 | 61.82 |
ResNet | ImageNet | 65.20 | 66.60 | 67.36 |

why does this matter for car insurance?
-
Speed without compromise: Insurance agents and garages need fast, reliable damage detection on smartphones or edge devices. The student model delivers rapid results, trained under the teacher’s expert supervision.
-
Resource efficiency: Smaller models reduce computational costs and power consumption, enabling scalable deployment across Thailand’s wide insurance ecosystem.
-
Robust accuracy: Guided by the teacher, the student avoids common pitfalls of lightweight models, maintaining high performance even in challenging real-world conditions.
Why This Matters for Car Insurance
-
Accuracy vs. Speed: ALBERT excels in detailed offline analysis, perfect for complex claim investigations. SLICK offers instant, reliable damage detection to accelerate frontline claim approvals and garage estimates.
-
Hardware Flexibility: ALBERT demands high-end GPUs; SLICK can run efficiently on more modest, real-world devices — a game changer for field agents and repair shops.
-
Knowledge Integration: SLICK’s use of insurance-specific metadata bridges the gap between raw image analysis and domain expertise, improving real-world applicability.
Mathematical Insight (Simplified)
At the heart of our system lies a sophisticated process that refines how the model understands and represents visual data at every step. Imagine ALBERT as a multi-layered brain that carefully adjusts its internal view of an image piece by piece. At each layer, it uses two powerful tools: one that lets it look broadly across different parts of the image to understand overall patterns (multi-scale self-attention), and another that processes these insights through focused, step-by-step reasoning (a multilayer perceptron).
$$ z^{(l+1)} = z^{(l)} + \text{MSA}(\text{LN}(z^{(l)})) + \text{MLP}(\text{LN}(z^{(l)})) $$
This dynamic combination helps ALBERT balance the big picture with fine details, ensuring that the model not only recognizes individual features but also how they relate to each other in context. To keep this learning smooth and stable, it applies a normalization step—similar to tuning an instrument—to make sure each layer’s output remains consistent and meaningful.
Parallel to this, SLICK operates like an intelligent curator, enhancing the model’s confidence in its predictions. It does this by merging two streams of knowledge: the direct visual cues from the image itself and additional information pulled from a structured knowledge graph—think of this as a database of domain-specific facts and relationships.
$$ s_{mask} = \sigma(W_q [f_{img} | f_{kg}]) + b $$
To blend these inputs effectively, SLICK employs a gating mechanism that acts like a smart filter or valve. This gate carefully weighs how much influence the visual data and the knowledge graph should each have in shaping the final mask quality scores. By doing so, the model doesn’t just rely on what it sees but also on what it knows about the world, leading to sharper, more reliable segmentation.
In essence, this combination of refined visual understanding and context-aware knowledge integration lets our system adapt its focus dynamically—prioritizing regions and details that matter most for accurate damage assessment and claim processing.
