Currently, the deep learning application in crop disease classification is the most active areas of research for which the prerequisite is an image dataset. (2010). Dropout: a simple way to prevent neural networks from overfitting. The data was labelled as integer class vectors to binary class matrices through one-hot encoding process. Also, the image should only contain the leaf for improving the accuracy rate. Furthermore, a CNN-based system was introduced for categorising multi-organ plant with the latest VGG net which is responsible for recognising organ features such fruits, flowers, and stems (Lee et al., 2016). Lee, S. H., Chan, C. S., Wilkin, P., & Remagnino, P. (2015). Goëau, H., Bonnet, P., & Joly, A. Many plant-identification studies are using CNN to recognise different local features of plants, such as fine-grained features and organ features. Firstly, training the CNN model by utilising unsupervised-learning method. Thirdly, the increase in the complexity of datasets will be necessary. This work uses Deep Convolutional Neural Network (CNN) to detect plant diseases from images of plant leaves and accurately classify them into 2 classes based on the presence and absence of disease. Constructs a two-dimensional pooling layer using the max-pooling algorithm. (2016) concluded that CNN is more effectual than the other computer-vision approaches on plant identification. The CNN model was trained by the images taken from two different species of trees in Auckland, New Zealand. The developed CNN model in this paper has an excellent performance on image classification of the training set and the test set, which is consistent with the previous research. presented at the meeting of the Proceedings of the Thirteenth International Conference on Artificial Intelligence and Statistics. <>

The examples of the leaf images are shown in Figure 1. Unsupervised learning would be a relatively important approach in the fields of computer vision and machine learning. Plants are an essential component of Earth’s ecosystem which is helpful for climate regulation, habitats preservation, food provision. The cross-entropy method is employed as the loss function (Deng, 2006). Solution is composed of four main phases; in the first phase Two areas need to be improved to enhance the reliability of the experimental results. Myanmar is an agricultural country and then crop production is one of the major sources of earning. Many organisations process application forms, such as loan applications, from it's customers. Supposing an L-layer ANN, which the input vector into the layer l and the output vector from the layer l during the feed-forward operation can be illustrated as (Figure 5a): where z, w, b, and y denote the input, weight, bias, output respectively, and f represents the activation function. These two species of trees are labelled as Tree1 and Tree2 in this paper. The CNN model has been proven to have a high ability to classify images by Krizhevsky et al. https://github.com/neoxu314/tree_leaf_identification. However, conventional manual plant classification is challenging and time-consuming caused by two reasons. In contrast, we propose a dual-path deep convolutional neural network (CNN) to (i) learn joint feature representations for leaf images, exploiting their shape and texture characteristics, and (ii) optimize these features for the classification task. CNNs was originally introduced by LeCun et al. We know that the machine’s perception of an image is completely different from what we see. However, there are several limitations of this research including the kind of tree species, the complexity of training data and test data, and the training method. This paper offers an overview analysis of current plant-based disease detection systems. According to Figure 2, a five-layer convolutional neural network was established for the leaf identification which is composed of two convolutional layers for the first two layers and three fully connected layers for the remaining three layers. Srivastava, N., Hinton, G. E., Krizhevsky, A., Sutskever, I., & Salakhutdinov, R. (2014). The dataset consists approximately 1,584 images of leaf specimens (16 samples each of 99 species) which have been converted to binary black leaves against white backgrounds. For example, the accuracy rate of the model on training sets is about 99% while the accuracy rate on test sets is merely approximately 70%.

Also, a pre-trained CNN system was suggested for plant categorisation based on the method of classifying fine-grained features; this system was trained by millions of ordinary-object images from ImageNet datasets (Sünderhauf, McCool, Upcroft, & Perez, 2016). Several zero columns and rows are used for padding in the convolutional operation, which means that the shape of the input data will not be changed after the convolutional operation. Identifying plant species based on photographs of their leaves is an important problem in computer vision and biology. First, a general purpose CNN image classification network was fine tuned to extract leaf image features or image embeddings. There are a few basic things about an Image Classification problem that you must know before you deep dive in building the convolutional neural network. In classifying various plant diseases, Great success has been achieved through deep learning with convolutional neural networks (CNNs). K. P. Ferentinos, Deep learning models for plant disease detection and diagnosis, Computers and Electronics in Agriculture, vol. To unveil the characteristics of visualization approaches for CNNs for plant disease diagnosis, we adopted various methods on a trained CNN model using a leaf disease dataset. The dataset contains 500 images of tomato leaves with four symptoms of diseases. In addition, the training method used in this research is purely supervised learning which absolutely would be restricted by the labelled data. Overfitting is reduced by the methods of data augmentation, dropout and pooling effectively. The latest generation of convolutional neural networks (CNNs) has achieved impressive results in the field of image classification. Secondly, the number of tree species for identification should be increased to make the model more practical. Sünderhauf, N., McCool, C., Upcroft, B., & Perez, T. (2016).
