Unverified1.58-bit refers to each weight occupying an average of log₂(3) ≈ 1.58 bits, because ternary weights (−1, 0, +1) have 3 possible states.77% similarPartially VerifiedWhen using the base-2 logarithm, the unit of entropy is bits, and when using the natural logarithm, the unit is nats.68% similarUnverifiedSince 2024, 1-bit quantization (such as the BitNet series) has entered academic attention, compressing weights to ternary values {-1, 0, +1}, and it is currently still in the research stage66% similarUnverifiedBitNet探索的极端量化（如2-bit或1.58-bit三值量化）在某些场景下也能保持较好性能65% similarUnverifiedQ3 quantization means each parameter is stored using approximately 3 bits61% similar
