    摘要:

    生成式對抗網(wǎng)絡是基于對抗過程生成數(shù)據(jù)模型的新框架,,它能夠生成高質(zhì)量的圖像數(shù)據(jù),,為解決小樣本數(shù)據(jù),、非均衡數(shù)據(jù)分析等提供了行之有效的方法,。菌菇作為重要的真菌之一,,其種類繁多,,數(shù)據(jù)長尾分布,、非均衡性等為其表型智能化識別與分類帶來了困難。針對蘑菇表型數(shù)據(jù),,設計了一個高效的蘑菇表型生成式對抗網(wǎng)絡MPGAN。研究了菌菇表型數(shù)據(jù)生成技術,,設計了用于菌菇表型數(shù)據(jù)生成的生成式對抗網(wǎng)絡結(jié)構(gòu),,系統(tǒng)分為模型訓練和表型圖像生成兩個模塊。為了提升生成質(zhì)量,,使用Wasserstein距離和帶有梯度懲罰的損失函數(shù),。利用開源數(shù)據(jù)和私有數(shù)據(jù)集測試學習率,、處理所需的批次數(shù)EPOCH與Wasserstein距離,。系統(tǒng)生成的菌菇表型數(shù)據(jù)為后期菌菇數(shù)據(jù)分類與識別提供了大數(shù)據(jù)基礎,。

    Abstract:

    Phenotypic data analysis based on image data and machine learning has become one of the important issues in interdisciplinary research. In recent years, the big data and deep learning techniques have provided powerful tools for image analysis and machine vision. Currently, the generative adversarial network is becoming a novel framework for the process estimation generation model. It can generate highquality image data and provide an effective approach for solving the problem of small sample data and unbalanced data analysis and so on. As one of the important fungi, mushroom has a plenty of varieties and the long tail distribution and nonequilibrium of the data distribution bring great difficulties to its phenotypic intelligent classification and identification. Aiming to design a highefficiency mushroom phenotyperesistance network MPGAN with mushroom phenotype data. The phenotypic data generation technology of mushroom was studied, and the generated confrontation network structure for mushroom phenotypic data generation was designed. The system was divided into two modules: model training and phenotypic image generation. To improve the quality of the generation, Wasserstein distances and loss functions with gradient penalty were used. Experiments were conducted on two datasets: open source data and private data sets, and results analysis were performed with the learning rate, number of batches required to process EPOCH and Wasserstein distances. The phenotypic data of the mushroom produced with this approach can furnish data basis for the classification of the mushroom data in the later stage, and provide solutions for solving the issues of unbalanced data and long tail distribution of the mushroom classification. The research can provide technical support for the study of high quality mushroom phenotypic data sets.
