kontekstvindue

A kontekstvindue, or context window, is a fundamental concept in the field of natural language processing (NLP), particularly in the architecture of transformer models. It refers to the fixed-size segment of input text that a model can consider at any given moment when processing information. Think of it as the model's short-term memory.

When a model processes a piece of text, it doesn't see the entire document or conversation at once. Instead, it looks at a portion of the text defined by its kontekstvindue. This window slides across the input, allowing the model to build an understanding of the relationships between words and phrases within that specific segment. The size of the kontekstvindue is a crucial hyperparameter, impacting the model's ability to grasp long-range dependencies and the overall coherence of its output.

A larger kontekstvindue generally enables a model to capture more context and understand more complex relationships between distant parts of the text. However, increasing the window size also significantly increases computational cost and memory requirements, making it a trade-off between performance and efficiency. Models with larger kontekstvinduer are better suited for tasks requiring an understanding of lengthy documents, intricate narratives, or extended conversations. Conversely, models with smaller windows might be more efficient for shorter texts or tasks where immediate context is sufficient. The development of techniques to effectively manage and expand the kontekstvindue is an ongoing area of research in NLP.
