Deep learning methods are one of the machine learning models which are having the similar working model of artificial neural network. The deep learning algorithms are used to process the information and enhance the thinking power. The deep learning methods have three different layers for processing namely input layer, hidden layer and output layer. In deep learning neural network, the primary layer is input layer.

The data is gone through each layer with appropriate computation process. The results are passes to the next layer in the network. Finally, the results will be given in output layer. Each layer contains some activation function to process the data.

Feature extraction is one of the powerful techniques which are used for image classification. Finding the appropriate features are more essential to classify the images. Features from the images are requires for training to learn. This process will help the algorithm to understand the class of the image.

Objective of the coursework

Image classification

Classification of images is one of the important processes of images processing. The primary objective of image classification is finding and categorizing the appropriate image using class labels. Generally there are two types of classification methods available.

Those are classification with supervised learning methods and classification with unsupervised learning methods. The process of image classification is categorized into two main stages such as Training the framework and Testing. These two stages are used for image classification with some data samples. The dataset can get collected from some UCI repository.

The natural image classification is the main objective of this research work. This classification identifies and categorizes some natural images like airplanes, automobiles, cat, dog, bird and etc. There are 10 different class of images were selected for this image classification. Deep learning methods are used for making image classification.

Overview of the coursework

Image classification efficiency is compared with two different methods (Cheng 2017). The researcher used classification of animal and bird image using deep neural network. They used inception v3 architecture type for this image classification. This model contained more than 50 layers in the network for image classification. The Recurrent neural network was used text classification of text whereas the convolutional neural network was used for image classification.

The transfer learning methods was used to get the enhanced accuracy. The used model produced 98% of classification accuracy with convolutional neural network. The transfer learning methods was used to process the data and transfer the knowledge to the next process. This kind of process can save the computation time and produce the higher accuracy.

New approaches of image classification are proposed (Liu 2015). Deep learning methods are used to provide the process of classifying the images. The data collection, pre-processing and feature extraction are the common steps in the process of image classification. Different classifiers are used for classification based on features. Features are extracted using various filters in machine learning.

The features are extracted based on three different components such as color, shape and texture. Convolutional neural network is used for this image classification process. This network contains four different layers for making classification effectively.

Deep learning kernel function is used for image classification (Luis Perez 2017). They highlighted that their research process had two different segments such as feature extraction and classification these methods are used for effective image classification. Deep learning methods have the capacity to produce feature extraction and classification of image.

The kernel functions are used for image classification. This method contains some set of process like data collection, pre-processing, Parameter initialization of network, feature extraction, apply training process for image and make classification. Three different layers are involved in this process that are input layer which is used to get the input values, hidden layer which are used to compute all the activation function to make feature extraction and the output layer  which is used to produce the results.

These three layers are mainly focusing the values which are given through some calculation. Convolutional neural network is used for image classification.

Deep learning methods are also used for medical image classification (Q.Zou 2015). Healthcare sector is one of the essential sectors which are used to provide treatment for various diseases to human. The used of deep learning methods are essential in the area of disease identification and prediction. Most of the diseases are identified using reports and symptoms.

The deep learning methods are used to identify the diseases using the medical images. The support vector machine and convolutional neural network methods are involved image identification process and classification. SVM is the powerful classifier which can produce more accuracy in image classification. The accurate identification of disease using image can be depends on two different processes. Those are image acquisition and image interpretation.

Image acquisition is used to collect some real medical images using tools. Image interpretation is used to extract the features in images which are helpful to identify the appropriate disease. Different diseases images are used in the ide notification and classification process with training of convolutional neural network.

Convolutional neural network was used in the image classification (Qishuo Gao 2018). This algorithm is effectively working on different dataset for the purpose of image classification. The performance evaluation was done with the help of some quality metrics such as Mean Squared Error (MSE) and accuracy in classification. The Feed Forward neural network is applied to get the higher accuracy in image classification. The dataset is divided for two different processes such as training the model and testing the efficiency.

The training methods are used to provide some learning process for identifying the images. The testing methods are used to evaluate the efficiency of the training model. The back propagation methods are used to adjust the weight of neural network for increasing the prediction accuracy. This convolutional neural network contains different architectures to produce the enhanced results.

Some innovations are proposed for image classification using the convolutional neural network (Spanhol 2016). Convolutional neural network used different architectures to produce the result. LeNet-5 is one of the important architecture of CNN. This research work produced some process to change this LeNet-5 into SENet model. This model can produce effective prediction in images identification and classification.

This LeNet-5 contains three convolutional layers and two pooling layers. This network type contains one fully connected layer and ReLu activation function for image classification. The classification process involves image acquisition and pre-processing methods. Feature extraction is one of the main parts for making image classification.

The automatic classification is done with the help of training process of neural network. This training helped the network to make classification effectively. MNIST dataset is selected for classification process. For training, the color images are converted into gray scale images. Using these images, the training has been given.

These methods are helpful to reduce the complexity in classification process. SVM is one of the famous machine learning classifiers which is used to produce the effective results on image classification. The complex classification process can be handled using this SVM for getting the improved results. The feature extraction is used to extract the important features to make the classification. Convolutional neural network contain various filters to make this extraction process of features.

The transfer learning approach is used in image classification (Wei Li. 2017). The convolutional neural network is used for making the classification process using different images. This network contains different layers such as input layer, convolutional layer, ReLu activation function, Pooling, Fully connected layer and Softmax layer. The transfer learning methods was used to transfer the gained knowledge to the next process for making the computation effectively.

This process depends on the selection of architecture type in convolutional neural network. There are five important architecture type was discussed in this research work. Those are LeNet, AlexNet, VGG, GoogLeNet and ResNet architectures. The pre-trained models are used for making the transfer learning method in image classification.
