Huawei Cloud ModelArts provides ModelBox for device-edge-cloud joint development. Which of the following are its optimization policies?
Huawei Cloud ModelArts provides ModelBox, a tool for device-edge-cloud joint development, enabling efficient deployment across multiple environments. Some of its key optimization policies include:
Hardware affinity: Ensures that the models are optimized to run efficiently on the target hardware.
Operator optimization: Improves the performance of AI operators for better model execution.
Automatic segmentation of operators: Automatically segments operators for optimized distribution across devices, edges, and clouds.
Model replication is not an optimization policy offered by ModelBox.
HarmonyOS can provide AI capabilities for external systems only through the integrated HMS Core.
HarmonyOS provides AI capabilities not only through HMS Core (Huawei Mobile Services Core), but also through other system-level integrations and AI frameworks. While HMS Core is one way to offer AI functionalities, HarmonyOS also has native support for AI processing that can be accessed by external systems or applications beyond HMS Core.
Thus, the statement is false as AI capabilities are not limited solely to HMS Core in HarmonyOS.

Which of the following are common gradient descent methods?
The gradient descent method is a core optimization technique in machine learning, particularly for neural networks and deep learning models. The common gradient descent methods include:
Batch Gradient Descent (BGD): Updates the model parameters after computing the gradients from the entire dataset.
Mini-batch Gradient Descent (MBGD): Updates the model parameters using a small batch of data, combining the benefits of both batch and stochastic gradient descent.
Stochastic Gradient Descent (SGD): Updates the model parameters for each individual data point, leading to faster but noisier updates.
Multi-dimensional gradient descent is not a recognized method in AI or machine learning.
Which of the following statements are true about the k-nearest neighbors (k-NN) algorithm?
The k-nearest neighbors (k-NN) algorithm is a non-parametric algorithm used for both classification and regression. In classification tasks, it typically uses majority voting to assign a label to a new instance based on the most common class among its nearest neighbors. The algorithm works by calculating the distance (often using Euclidean distance) between the query point and the points in the dataset, and then assigning the query point to the class that is most frequent among its k nearest neighbors.
For regression tasks, k-NN can predict the outcome based on the mean of the values of the k nearest neighbors, although this is less common than its classification use.
When learning the MindSpore framework, John learns how to use callbacks and wants to use it for AI model training. For which of the following scenarios can John use the callback?
In MindSpore, callbacks can be used in various scenarios such as:
Early stopping: To stop training when the performance plateaus or certain criteria are met.
Saving model parameters: To save checkpoints during or after training using the ModelCheckpoint callback.
Monitoring loss values: To keep track of loss values during training using LossMonitor, allowing interventions if necessary.
Adjusting the activation function is not a typical use case for callbacks, as activation functions are usually set during model definition.
