Mamba is a new state space model architecture showing promising performance on information-dense data such as language modeling, where previous subquadratic models fall short of Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of FlashAttention.

你能解释一下这部分吗？
having count( distinct value ) = 2这是否意味着如果我要选择A，B和C，它将变成= 3？Does it mean that if i want to select A, B, and C than it will become = 3， 对，那是正确的@Yusufmm-您也需要
C在where子句中，where value in ('A', 'B', 'C')非常感谢你。
