Was ist die Keras 3-Version dieser Numpy-Funktion dieser IEEE754-zu-Unsigned-Integer-8-Normalisierung? ⇐ Python

[Guest]

Was ist die Keras 3-Version dieser Normalisierungsfunktion unter Verwendung der Keras 3-Ops-API?

Code: Select all

def ieee754_to_uint8(x, axis=-1):
"""
Normalize a tensor using IEEE 754 logic and map it to uint8 values.

Args:
x (tensor): A Keras tensor of shape (batch_size, seq_len).
axis (int): Axis along which to normalize.

Returns:
A Keras tensor with dtype uint8, returning the same shape as input x.
"""
# Find the maximum absolute value in x
m = np.max(np.abs(x), axis=axis, keepdims=True)
m[m==0] = 1

y = (2**7 - 1 * (x > 0)) * x / m
return (y.astype(int) + 128).astype(np.uint8)
