H13-311_V3.5 Exam Dumps : HCIA-AI V3.5 Exam

In MindSpore, when you define a tensor using Tensor(np.array([[1, 2], [3, 4]]), dtype.int32), the dtype attribute returns the data type of the tensor, which in this case is mindspore.int32. This specifies the type of elements in the tensor.

In a convolutional neural network (CNN), each kernel (also called a filter) in the same convolutional layer does not share weights with other kernels. Each kernel is independent and learns different weights during training to detect different features in the input data. For instance, one kernel might learn to detect edges, while another might detect textures.

However, the same kernel’s weights are shared across all spatial positions it moves across the input feature map. This concept of weight sharing is what makes CNNs efficient and well-suited for tasks like image recognition.

Thus, the statement that all kernels share weights is false.

Deep Learning Overview: Detailed description of CNNs, focusing on kernel operations and weight sharing mechanisms within a single kernel, but not across different kernels.

The pad_mode parameter in mindspore.nn.Conv2d() can take values such as:

same: Ensures the output has the same spatial dimensions as the input.

valid: Performs convolution without padding, resulting in an output smaller than the input.

Other values like "pad" and "nopadding" are not valid options for the pad_mode parameter.
