Embodiment

[0065] First, prepare a certain number of data sets, including the following attributes:

[0066] Picture: JPEGImages picture file;

[0067] Annotations: annotations tag file;

[0068] Classes:

[0069] "aeroplane","bicycle","bird","boat","bottle","bus","car","cat","chair",

[0070] "cow","diningtable","dog","horse","motorbike","person","pottedplant","sheep","sofa",

[0071] Class files for "train", "tvmonitor".

[0072] Extract the feature information in the data set, including the read image size, target size, position, coordinates, quantity and other information.

[0073] Then analyze these feature information, and get the analysis report of the data set according to the above analysis method. The number of small targets in the data set and the number of occlusion problems can be obtained through statistical analysis. The difference in the number of different categories is not obvious (less than 2). Except for the large number of person and chair categories, the number...

Abstract

The invention provides a data set feature analysis method and device, and the method comprises the following steps: preparing a plurality of data sets with specific attributes, carrying out the feature extraction of files in the data sets, and carrying out the classification according to different features; analyzing each classified feature to obtain an analysis result of each feature; judging whether an analysis result of each feature meets a threshold requirement or not; in response to the fact that the analysis result does not meet the threshold requirement, improving the corresponding algorithm for the feature which do not meet the threshold requirement. By using the scheme provided by the invention, the problem of how to select the algorithm suitable for the current data set or make improvement on the existing algorithm by analyzing the characteristics of the data set when facing the data sets of different scenes can be solved, convenience is provided for algorithm application andalgorithm research and development personnel, and the algorithm development efficiency is improved.

Description

technical field [0001] This field relates to the computer field, and more particularly relates to a method and device for feature analysis of data sets. Background technique [0002] With the development of artificial intelligence technology, models centered on deep neural networks have been widely used in speech recognition, target detection, image classification and other fields. However, different target detection algorithms are suitable for solving different problems. For example, yolov3 is suitable for solving small target problems, and RetinaFace is suitable for solving occlusion problems. For target detection tasks in practical application scenarios, it is necessary to construct a suitable algorithm based on the target features in the data set, and this process relies on strong expert experience. In addition, in order to verify whether the algorithm is suitable, it usually requires repeated trial and error, resulting in low algorithm design efficiency. The current d...
