Latest news from Analytics Vidhya on our Hackathons and some of our best articles! (11):34–38, 2011. i. Build your First Image Classification Model in just 10 Minutes! For example, if the network is given a task to recognize a face, the first hidden layer might act as a line detector, the second hidden takes these lines as input and puts them together to form a nose, the third hidden layer takes the nose and matches it with an eye and so on, until finally the whole face is constructed. In both cases, the input consists of the k closest training examples in the feature space. The features in next layer are convoluted with different filters to generate more invariant and abstract features and the process continues till it gets final feature/output which is invariant to occlusions. You will gain the hands-on experience of applying advanced machine learning techniques that provide the foundation to the current state-of-the art in AI. A technique is a way of solving a problem. The training needs softwares and tools like classifiers, which feed huge amount of data, analyze them and extract useful features. Although simple, there are near-infinite ways to arrange these layers for a given computer vision problem. The objective of image classification is to identify and portray, as a unique gray level (or color), the features occurring in an image in terms of the object these features actually represent on the ground. It is a type of signal processing in which input is an image and output may be image or characteristics/features associated with that image. In particular, great strides have been made in the development of digital image processing techniques for remote sensing data. Support vector machines have their unique way of implementation as compared to other machine learning algorithms.
