7 min readA batch in TensorFlow refers to a set of input data samples that are processed together in one iteration of the training or inference algorithm. It is a commonly used concept in deep learning frameworks, including TensorFlow, to improve computational efficiency.When training a deep learning model, it is often inefficient to process the entire dataset at once due to memory constraints or limited computational resources. Hence, the dataset is divided into smaller subsets called batches.

4 min readTo scale a tensor in TensorFlow, you can multiply it with a scalar value using the TensorFlow multiplication operator. This operation performs element-wise multiplication, scaling each element of the tensor.Here is an example of scaling a tensor named input_tensor by a scalar value of 2.0: scaled_tensor = input_tensor * 2.0 In the above code, the * operator multiplies each element of input_tensor by 2.0, resulting in a new tensor scaled_tensor which contains the scaled values.
