Stratified LLM Subsets: Balanced Training Data at 100K-1M Scale
Released three training datasets using embedding-based k-means clustering to create balanced subsets from large-scale corpora:
Interactive cluster visualization:

Pre-Training (FineWeb-Edu + Proof-Pile-2)
AmanPriyanshu/stratified-kmeans-diverse-pretraining-100K-1M
Instruction-Following (Tulu-3 + Orca AgentInstruct)
AmanPriyanshu/stratified-kmeans-diverse-instruction-following-100K-1M
Reasoning (Llama-Nemotron with sqrt balancing)
AmanPriyanshu/stratified-kmeans-diverse-reasoning-100K-1M
Methodology: k-means clustering on Snowflake Arctic-embed-xs embeddings (100 iterations), selecting cluster centroids as representatives. Balancing applied to imbalanced datasets to reduce category dominance.
Available at 50k, 100k, 250k, 500k, and 1M scales.
