Question 36

The following about KNN Algorithm k The value description is correct?

A.K The larger the value, the easier the model is to overfit

B.K The larger the value, the smoother the segmentation surface of the classification

C.K Value is a hyperparameter

D.can k Value is set to 0

Question 37

On-Device Execution, that is, the entire image is offloaded and executed, and the computing power of the Yiteng chip can be fully utilized, which can greatly reduce the interaction overhead, thereby increasing the accelerator occupancy rate. On-Device The following description is wrong?

A.MindSpore Realize decentralized autonomy through adaptive graph optimization driven by gradient data A11 Reduce, Gradient aggregation is in step, and calculation and communication are fully streamlined

B.The challenge of distributed gradient aggregation under super chip computing power:ReslNet50 Single iteration 20ms Time will be generated The synchronization overhead of heart control and the communication overhead of frequent synchronization. Traditional methods require 3 Synchronization completed A11 Reduce, Data-driven method autonomy A11 Reduce, No control overhead

C.Challenges of model execution under super chip computing power: Memory wall problems, high interaction overhead, and difficulty in data supply. Partly in Host Executed, partly in Device Execution, interaction overhead is even much greater than execution overhead, resulting in low accelerator occupancy

D.MindSpore Through the chip-oriented depth map optimization technology, the synchronization wait is less, and the "data computing communication" is maximized. The parallelism of "trust", compared with training performance Host Side view scheduling method is flat

Question 38

TensorFlow supports multi-TPU cluster computing. Correct 5. What is the description about the deep feedforward network?

A.deep feedforward network is a kind of neural network

B.there are generally countless units on the hidden layer of the deep feedforward network

C.the deep feedforward network is used to deal with linear problems

D.The deep feedforward network has only one hidden layer.

Question 39

Deflated AI The logical architecture of the processor does not include which of the following options?

A.Chip system control CPU

B.DVPP

C.AI Calculation engine

D.GPU

Question 40

Python language can use "#" at the beginning of a single line of code for code comments.

A.False

B.True
