Tensorflow.js tf.mean() Function
Tensorflow.js is an open-source library developed by Google for running machine learning models and deep learning neural networks in the browser or node environment.
The tf.mean() function is used to calculate the mean value of the specified Tensor across its dimension. It reduces the given input elements along the dimensions of axes. If the parameter “keepDims” is true, the reduced dimensions are retained with length 1 else the rank of Tensor is reduced by 1. If the axes parameter has no entries, it returns a Tensor with a single element with all reduced dimensions.
tf.mean (x, axis?, keepDims?)
Parameters: This function accepts three parameters which are illustrated below:
- x: The input tensor for which mean value is being computed.
- axis: The specified dimension(s) to reduce. By default it reduces all dimensions. It is optional parameter.
- keepDims: If this parameter value is true, it retains reduced dimensions with length 1 else the rank of Tensor is reduced by 1. It is also optional parameter.
Return Value: It returns a Tensor of mean value.
