Sliding Window Chunking With Configurable Stride

via “sliding-window chunking with configurable stride”

Show HN: RAG-chunk – A CLI to test RAG chunking strategies

Unique: Provides explicit sliding-window implementation with independent control of window size and stride, enabling fine-grained tuning of chunk overlap and coverage without code modification

vs others: More flexible than fixed-size chunking for controlling overlap, and simpler to tune than semantic chunking while providing predictable chunk sizes

via “long-horizon trajectory segmentation and windowing”

Dataset by cadene. 3,11,762 downloads.

Unique: Provides configurable trajectory windowing with automatic boundary handling and metadata tracking, enabling efficient conversion of variable-length episodes to fixed-size windows without manual preprocessing

vs others: Eliminates the need for custom windowing logic in training code, which is error-prone and often introduces subtle bugs in boundary handling and data leakage
