BERT’s NSP task involves pairing sentences where 50% are consecutive and 50% are randomly chosen from the corpus for the model to predict.
Next Sentence Prediction is a pretraining task in BERT where the model predicts whether a given sentence logically follows another. This enables BERT to capture inter-sentence relationships, improving performance on tasks like question answering, natural language inference, and conversational AI. NSP complements masked language modeling, providing bidirectional contextual representations that include sentence-level coherence.
💥 Impact (click to read)
Next sentence prediction improved BERT’s understanding of sentence relations, enhancing performance in complex NLP applications like reading comprehension and dialogue systems.
For users, NSP ensures AI responses consider logical sentence flow. The irony is that BERT predicts relationships statistically, simulating coherence without awareness.
