False

NO.127 The three main problems of ________ include evaluation problems, decoding problems, and learning problems.

HMM, Chinese name is “Hidden Markov Model”

NO.128 The larger the image sampling interval, the higher the spatial resolution of the image, and thus the better the image quality.

Model Deployment

Model Training

Data processing

Model Management

algorithm development

NO.143 What are the basic tasks of image recognition? (Multiple choice)

NO.145 The upper limit of IoU prediction is 100%.

True

False

NO.146 What text annotation tasks does ModelArts support?

Text Classification

Name recognition

Text triples

All of the above are true

NO.147 Which of the following descriptions of the bimodal adaptive threshold segmentation method are correct? (Multiple choice)

The bimodal method divides the image into foreground and background according to the grayscale characteristics of the image. The larger the inter-class variance between the foreground and the background, the greater the difference between the two parts that make up the image.

If the image grayscale histogram is obviously bimodal, the grayscale value corresponding to the valley between the two peaks is selected as the threshold for image segmentation.

Histogram bimodal method is an easy-to-understand adaptive threshold algorithm

If the grayscale histogram of the image is very flat or has multiple peaks, the bimodal method cannot be used to obtain a suitable threshold.

NO.148 Which of the following statements about the sigmoid function is correct? (Multiple choice)

Sigmoid function is monotonous and continuous, easy to derive, bounded output, and the network is easy to converge.

When the network is very deep, the modulus of the gradient becomes smaller and smaller

Generally speaking, within 5 layers of Sigmoid network, the gradient will degenerate to 0, making it difficult to train. This phenomenon is called the vanishing gradient phenomenon.

Sigmoid output is not centered on 0

NO.149 The XOR problem refers to the prediction of an output obtained through an XOR logic gate for two given binary inputs. When the inputs are not equal, the output is 1, otherwise the output is 0. ()

True

False
