Performs extractive QA by fine-tuned RoBERTa-large encoder that predicts start and end token positions within a passage to extract answer spans. Uses transformer-based sequence classification with token-level logits to identify answer boundaries, trained on Vietnamese SQuAD-format datasets with cross-lingual transfer from English pre-training. Architecture leverages masked language modeling representations to contextualize Vietnamese text and identify semantically relevant answer spans without generating new text.
Unique: RoBERTa-large backbone fine-tuned specifically on Vietnamese SQuAD data, combining English pre-training knowledge with Vietnamese-specific downstream task adaptation; uses token-level span prediction rather than generative decoding, enabling deterministic answer extraction directly from source passages
vs alternatives: Outperforms monolingual Vietnamese models and English-only QA systems on Vietnamese benchmarks due to large pre-trained encoder, while remaining faster and more interpretable than generative Vietnamese QA models that require autoregressive decoding
Leverages RoBERTa-large's multilingual pre-training (trained on 100+ languages including Vietnamese and English) to transfer knowledge from English SQuAD fine-tuning to Vietnamese QA tasks. The model architecture preserves language-agnostic contextual representations learned during pre-training, allowing the token classification head to generalize across Vietnamese and English without explicit cross-lingual alignment. Fine-tuning on Vietnamese SQuAD data adapts the shared encoder representations while maintaining transfer benefits from English QA patterns.
Unique: Inherits multilingual RoBERTa-large pre-training (100+ languages) rather than monolingual Vietnamese encoders, enabling zero-shot cross-lingual transfer from English SQuAD patterns to Vietnamese without explicit alignment layers or dual-encoder architectures
vs alternatives: Achieves better Vietnamese QA performance with less Vietnamese training data than monolingual models, while remaining simpler than explicit cross-lingual methods (e.g., mBERT with alignment layers) due to RoBERTa's implicit multilingual representation space
Supports standard SQuAD format input/output (JSON with passages, questions, answers with character offsets) for both training and evaluation. The model integrates with HuggingFace Datasets library to load SQuAD-compatible data, compute exact-match and F1 metrics during training, and enable reproducible benchmarking. Fine-tuning pipeline handles tokenization, token-to-character offset mapping, and loss computation for span prediction without requiring custom data loaders.
Unique: Integrates HuggingFace Datasets library for native SQuAD format support, enabling zero-configuration fine-tuning on Vietnamese SQuAD variants without custom data pipeline code; includes built-in metric computation (EM, F1) during training
vs alternatives: Simpler than building custom SQuAD loaders and metric computation from scratch, while maintaining compatibility with standard QA benchmarking practices across English and Vietnamese datasets
Outputs logit scores for start and end token positions, enabling confidence-based answer filtering and ranking. The model computes softmax probabilities over all tokens in the passage for both start and end positions, allowing downstream systems to rank candidate answers by joint probability (start_prob × end_prob) or filter low-confidence predictions. This enables uncertainty quantification and selective answer suppression in production systems.
Unique: Exposes token-level logit scores for both start and end positions, enabling fine-grained confidence analysis and joint probability ranking rather than simple argmax selection; allows downstream filtering without retraining
vs alternatives: Provides more granular confidence information than binary correct/incorrect labels, enabling production systems to implement confidence thresholds and fallback strategies without requiring ensemble methods or calibration layers
Supports efficient batch processing of multiple passage-question pairs through HuggingFace Transformers pipeline API, which handles tokenization, batching, and output aggregation.

Batch size can be tuned for memory/latency tradeoffs on different hardware.
Unique: Integrates with HuggingFace Transformers pipeline API for automatic batching and padding, eliminating manual batch assembly code; supports dynamic batch sizing and GPU memory management without custom CUDA kernels
vs alternatives: Simpler than building custom batching logic with PyTorch DataLoaders, while providing better GPU utilization than single-request inference through automatic padding and batch aggregation
Model is compatible with Azure ML endpoints for serverless inference deployment, enabling pay-per-use QA without managing infrastructure. Azure integration handles model versioning, auto-scaling based on request volume, and REST API exposure. The model can be deployed as a managed endpoint with configurable compute resources (CPU/GPU), enabling cost-optimized inference for variable traffic patterns.
Unique: Pre-configured for Azure ML endpoints deployment, eliminating custom containerization and endpoint configuration; supports auto-scaling and managed model versioning through Azure native services
vs alternatives: Simpler than self-hosted deployment on VMs or Kubernetes, while providing automatic scaling and monitoring that would require additional infrastructure code in self-hosted setups
Converts variable-length text sequences into fixed-dimensional dense vector representations (768-dim) using a transformer-based architecture (MPNet) trained on 215M+ sentence pairs. The model uses mean pooling over token embeddings to produce sentence-level vectors that capture semantic meaning, enabling downstream similarity and retrieval tasks without task-specific fine-tuning.
Unique: Uses MPNet (Masked and Permuted Language Modeling) architecture with mean pooling trained on 215M+ diverse sentence pairs (S2ORC, MS MARCO, StackExchange, Yahoo Answers, CodeSearchNet) rather than single-task fine-tuning, achieving state-of-the-art performance on 14+ downstream tasks without task-specific adaptation

Enables semantic similarity computation between text pairs by projecting both inputs into a shared 768-dimensional vector space where cosine distance correlates with semantic relatedness. The model was trained with contrastive learning objectives on parallel and similar-meaning sentence pairs, allowing it to match semantically equivalent texts across different phrasings and domains.
Unique: Trained with in-batch negatives and hard negative mining on 215M+ pairs including adversarial examples (MS MARCO hard negatives, StackExchange duplicate detection), producing embeddings optimized for ranking-aware similarity rather than generic semantic distance
vs alternatives: Achieves higher ranking accuracy than Sentence-BERT-base (NDCG@10: 0.68 vs 0.61) on MS MARCO while maintaining 2.5x faster inference than cross-encoder rerankers due to symmetric embedding computation
all-mpnet-base-v2 scores higher at 55/100 vs vi-mrc-large at 36/100.
