Performs pixel-level semantic segmentation using a SegFormer B0 transformer encoder-decoder architecture fine-tuned on ADE20K dataset. The model uses hierarchical self-attention blocks to capture multi-scale contextual information, then applies a lightweight MLP decoder to produce per-pixel class predictions across 150 ADE20K semantic categories. Inference runs via ONNX Runtime for CPU/GPU acceleration without requiring PyTorch.
Unique: Lightweight B0 variant (3.7M parameters) with hierarchical transformer encoder enables efficient client-side inference via ONNX, avoiding cloud API calls; pre-quantized to 8-bit reduces model size to ~15MB while maintaining ADE20K accuracy within 2-3% of original
vs alternatives: Smaller and faster than DeepLabV3+ (59M params) for browser deployment, more accurate than FCN-based segmentation on complex indoor scenes due to transformer attention, and open-source unlike proprietary cloud APIs (Google Vision, AWS Rekognition)
Decodes segmentation logits into 150 semantic class labels from the ADE20K ontology (walls, floors, furniture, vegetation, sky, etc.). The decoder applies argmax over the 150-dimensional class dimension per pixel, optionally with confidence thresholding or softmax probability extraction. Supports both single-image and batch inference with vectorized operations.
Unique: Integrates ADE20K's 150-class ontology with hierarchical scene understanding — classes are organized by spatial context (indoor vs outdoor, furniture vs architecture) enabling downstream filtering and reasoning without custom label mapping
vs alternatives: More granular than COCO segmentation (80 classes) for indoor scene understanding, and includes scene-context labels (wall, floor, ceiling) that generic object detectors omit
Executes the quantized SegFormer model directly in browser or Node.js using ONNX Runtime WebAssembly backend, eliminating server-side inference dependencies. The model is pre-converted to ONNX format and quantized to 8-bit integers, reducing size from ~60MB (float32) to ~15MB. Transformers.js library provides a high-level API wrapping ONNX Runtime with automatic model downloading and caching.
Unique: Pre-quantized ONNX model with transformers.js wrapper abstracts ONNX Runtime complexity — developers call single-line API (pipeline('image-segmentation', model)) without managing tensor conversion, memory allocation, or model loading
vs alternatives: Smaller and faster than TensorFlow.js for segmentation (no need to reimplement model architecture in JS), more privacy-preserving than cloud APIs (Google Vision, AWS), and zero infrastructure cost vs self-hosted inference servers
SegFormer B0 encoder uses hierarchical transformer blocks with overlapping patch embeddings to extract features at 4 scales (1/4, 1/8, 1/16, 1/32 of input resolution). Each scale captures different receptive fields — lower scales detect fine details (edges, small objects), higher scales capture global context (scene layout, large regions). The decoder fuses these multi-scale features via upsampling and concatenation before final classification.
Unique: Overlapping patch embeddings (vs non-overlapping in ViT) enable smoother feature transitions across scales, reducing boundary artifacts; hierarchical design with 4 scales balances efficiency (B0 is lightweight) with expressiveness
vs alternatives: More efficient multi-scale processing than FPN-based models (ResNet+FPN) because transformer self-attention naturally captures multi-scale context without explicit feature pyramid construction
The model is pre-quantized to 8-bit integer precision using post-training quantization, reducing model size from ~60MB (float32) to ~15MB while maintaining inference speed on CPU/GPU. Quantization maps float32 weights and activations to int8 range using learned scale factors per layer. ONNX Runtime automatically dequantizes to float32 during computation, introducing minimal accuracy loss (~1-3%) while dramatically reducing memory bandwidth and model download size.
Unique: Post-training quantization applied to pre-trained SegFormer B0 without retraining — uses per-channel scale factors for weights and per-tensor scale factors for activations, optimized for ONNX Runtime's quantization-aware execution
vs alternatives: Simpler than quantization-aware training (no retraining required), smaller than float32 baseline while maintaining comparable accuracy to knowledge distillation approaches, and directly compatible with ONNX Runtime without custom kernels
Provides pre-trained 100-dimensional word embeddings derived from GloVe (Global Vectors for Word Representation) trained on English corpora. The embeddings are stored as a compact, browser-compatible data structure that maps English words to their corresponding 100-element dense vectors. Integration with wink-nlp allows direct vector retrieval for any word in the vocabulary, enabling downstream NLP tasks like semantic similarity, clustering, and vector-based search without requiring model training or external API calls.
Unique: Lightweight, browser-native 100-dimensional GloVe embeddings specifically optimized for wink-nlp's tokenization pipeline, avoiding the need for external embedding services or large model downloads while maintaining semantic quality suitable for JavaScript-based NLP workflows
vs alternatives: Smaller footprint and faster load times than full-scale embedding models (Word2Vec, FastText) while providing pre-trained semantic quality without requiring API calls like commercial embedding services (OpenAI, Cohere)
Enables calculation of cosine similarity or other distance metrics between two word embeddings by retrieving their respective 100-dimensional vectors and computing the dot product normalized by vector magnitudes. This allows developers to quantify semantic relatedness between English words programmatically, supporting downstream tasks like synonym detection, semantic clustering, and relevance ranking without manual similarity thresholds.
Unique: Direct integration with wink-nlp's tokenization ensures consistent preprocessing before similarity computation, and the 100-dimensional GloVe vectors are optimized for English semantic relationships without requiring external similarity libraries or API calls
vs alternatives: Faster and more transparent than API-based similarity services (e.g., Hugging Face Inference API) because computation happens locally with no network latency, while maintaining semantic quality comparable to larger embedding models
segformer-b0-finetuned-ade-512-512 scores higher at 42/100 vs wink-embeddings-sg-100d at 24/100. segformer-b0-finetuned-ade-512-512 leads on adoption and quality, while wink-embeddings-sg-100d is stronger on ecosystem.

Retrieves the k-nearest words to a given query word by computing distances between the query's 100-dimensional embedding and all words in the vocabulary, then sorting by distance to identify semantically closest neighbors. This enables discovery of related terms, synonyms, and contextually similar words without manual curation, supporting applications like auto-complete, query suggestion, and semantic exploration of language structure.
Unique: Leverages wink-nlp's tokenization consistency to ensure query words are preprocessed identically to training data, and the 100-dimensional GloVe vectors enable fast approximate nearest-neighbor discovery without requiring specialized indexing libraries
vs alternatives: Simpler to implement and deploy than approximate nearest-neighbor systems (FAISS, Annoy) for small-to-medium vocabularies, while providing deterministic results without randomization or approximation errors
Computes aggregate embeddings for multi-word sequences (sentences, phrases, documents) by combining individual word embeddings through averaging, weighted averaging, or other pooling strategies. This enables representation of longer text spans as single vectors, supporting document-level semantic tasks like clustering, classification, and similarity comparison without requiring sentence-level pre-trained models.
Unique: Integrates with wink-nlp's tokenization pipeline to ensure consistent preprocessing of multi-word sequences, and provides simple aggregation strategies suitable for lightweight JavaScript environments without requiring sentence-level transformer models
vs alternatives: Significantly faster and lighter than sentence-level embedding models (Sentence-BERT, Universal Sentence Encoder) for document-level tasks, though with lower semantic quality — suitable for resource-constrained environments or rapid prototyping
Supports clustering of words or documents by treating their embeddings as feature vectors and applying standard clustering algorithms (k-means, hierarchical clustering) or dimensionality reduction techniques (PCA, t-SNE) to visualize or group semantically similar items. The 100-dimensional vectors provide sufficient semantic information for unsupervised grouping without requiring labeled training data or external ML libraries.
Unique: Provides pre-trained semantic vectors optimized for English that can be directly fed into standard clustering and visualization pipelines without requiring model training, enabling rapid exploratory analysis in JavaScript environments
vs alternatives: Faster to prototype with than training custom embeddings or using API-based clustering services, while maintaining semantic quality sufficient for exploratory analysis — though less sophisticated than specialized topic modeling frameworks (LDA, BERTopic)
