BinaryVector |
100 |
Binary vector. Each dimension is represented by 1 bit. |
FloatVector |
101 |
Float vector. Each dimension is represented by 1 float(4 bits) value. |
Float16Vector |
102 |
Float16 vector. Each dimension is a 16-bit half-precision floating-point number. |
BFloat16Vector |
103 |
BFloat16 vector. Each dimension is a 16-bit floating-point number with reduced precision but the same exponent range as Float32. |
SparseFloatVector |
104 |
Sparse vectors represent words or phrases using vector embeddings where most elements are zeros. A sparse vector is a list of key-value pairs, the key type is an unsigned integer and the value type is Float32. |
