Returns the index with the smallest value across axes of a tensor.
tf.math.argmin(
input,
axis=None,
output_type=tf.dtypes.int64
,
name=None
)
Returns the smallest index in case of ties.
Args |
input
|
A Tensor . Must be one of the following types: float32 , float64 ,
int32 , uint8 , int16 , int8 , complex64 , int64 , qint8 ,
quint8 , qint32 , bfloat16 , uint16 , complex128 , half , uint32 ,
uint64 .
|
axis
|
A Tensor . Must be one of the following types: int32 , int64 .
int32 or int64, must be in the range -rank(input), rank(input)) .
Describes which axis of the input Tensor to reduce across. For vectors,
use axis = 0.
|
output_type
|
An optional tf.DType from: tf.int32, tf.int64 . Defaults to
tf.int64 .
|
name
|
A name for the operation (optional).
|
Returns |
A Tensor of type output_type .

Usage:
import tensorflow as tf
a = [1, 10, 26.9, 2.8, 166.32, 62.3]
b = tf.math.argmin(input = a)
c = tf.keras.backend.eval(b)
# c = 0
# here a[0] = 1 which is the smallest element of a across axis 0
