# BNNSDataLayoutNSE

A constant that represents a 3D tensor with the size elements embedding dimension, sequence length, and batch size.

## Declaration

```swift
var BNNSDataLayoutNSE: BNNSDataLayout { get }
```

## Discussion

Discussion The value (e, s, n) is at index e * stride[0] + s * stride[1] + n * stride[2]. size[0] is the embedding dimension (e). size[1] is the sequence length (s). size[2] is the batch size (n).
