`Dot`

class```
keras.layers.Dot(axes, normalize=False, **kwargs)
```

Computes element-wise dot product of two tensors.

It takes a list of inputs of size 2, and the axes corresponding to each input along with the dot product is to be performed.

Let's say `x`

and `y`

are the two input tensors with shapes
`(2, 3, 5)`

and `(2, 10, 3)`

. The batch dimension should be
of same size for both the inputs, and `axes`

should correspond
to the dimensions that have the same size in the corresponding
inputs. e.g. with `axes=(1, 2)`

, the dot product of `x`

, and `y`

will result in a tensor with shape `(2, 5, 10)`

**Example**

```
>>> x = np.arange(10).reshape(1, 5, 2)
>>> y = np.arange(10, 20).reshape(1, 2, 5)
>>> keras.layers.Dot(axes=(1, 2))([x, y])
```

Usage in a Keras model:

```
>>> x1 = keras.layers.Dense(8)(np.arange(10).reshape(5, 2))
>>> x2 = keras.layers.Dense(8)(np.arange(10, 20).reshape(5, 2))
>>> y = keras.layers.Dot(axes=1)([x1, x2])
```

**Arguments**

**axes**: Integer or tuple of integers, axis or axes along which to take the dot product. If a tuple, should be two integers corresponding to the desired axis from the first input and the desired axis from the second input, respectively. Note that the size of the two selected axes must match.**normalize**: Whether to L2-normalize samples along the dot product axis before taking the dot product. If set to`True`

, then the output of the dot product is the cosine proximity between the two samples.****kwargs**: Standard layer keyword arguments.

**Returns**

A tensor, the dot product of the samples from the inputs.
