ETS is the fastest-growing and largest engineering school in Quebec, with an expanding team of highly qualified young researchers in image analysis, one of the priority areas of the school.
Deep learning is a class of machine learning algorithms that: Each successive layer uses the output from the previous layer as input. Overview[ edit ] Most modern deep learning models are based on an artificial neural networkalthough they can also include propositional formulas or latent variables organized layer-wise in deep generative models such as the nodes in deep belief networks and deep Boltzmann machines.
In an image recognition application, the raw input may be a matrix of pixels; the first representational Thesis on image inpainting may abstract the pixels and encode edges; the second layer may compose and encode arrangements of edges; the third layer may encode a nose and eyes; and the fourth layer may recognize that the image contains a face.
Importantly, a deep learning process can learn which features to optimally place in which level on its own. Of course, this does not completely obviate the need for hand-tuning; for example, varying numbers of layers and layer sizes can provide different degrees of abstraction.
More precisely, deep learning systems have a substantial credit assignment path CAP depth. The CAP is the chain of transformations from input to output.
CAPs describe potentially causal connections between input and output. For a feedforward neural networkthe depth of the CAPs is that of the network and is the number of hidden layers plus one as the output layer is also parameterized.
For recurrent neural networksin which a signal may propagate through a layer more than once, Thesis on image inpainting CAP depth is potentially unlimited. CAP of depth 2 has been shown to be a universal approximator in the sense that it can emulate any function. Deep learning architectures are often constructed with a greedy layer-by-layer method.
Deep learning algorithms can be applied to unsupervised learning tasks. This is an important benefit because unlabeled data are more abundant than labeled data.
Examples of deep structures that can be trained in an unsupervised manner are neural history compressors  and deep belief networks.
It features inference,       as well as the optimization concepts of training and testingrelated to fitting and generalizationrespectively. More specifically, the probabilistic interpretation considers the activation nonlinearity as a cumulative distribution function.
While the algorithm worked, training required 3 days. Because it directly used natural images, Cresceptron started the beginning of general-purpose visual learning for natural 3D worlds.
Cresceptron is a cascade of layers similar to Neocognitron. But while Neocognitron required a human programmer to hand-merge features, Cresceptron learned an open number of features in each layer without supervision, where each feature is represented by a convolution kernel. Cresceptron segmented each learned object from a cluttered scene through back-analysis through the network.
Max poolingnow often adopted by deep neural networks e. ImageNet testswas first used in Cresceptron to reduce the position resolution by a factor of 2x2 to 1 through the cascade for better generalization.
Each layer in the feature extraction module extracted features with growing complexity regarding the previous layer. Both shallow and deep learning e. Most speech recognition researchers moved away from neural nets to pursue generative modeling.
An exception was at SRI International in the late s. Heck's speaker recognition team achieved the first significant success with deep neural networks in speech processing in the National Institute of Standards and Technology Speaker Recognition evaluation.
The principle of elevating "raw" features over hand-crafted optimization was first explored successfully in the architecture of deep autoencoder on the "raw" spectrogram or linear filter-bank features in the late s,  showing its superiority over the Mel-Cepstral features that contain stages of fixed transformation from spectrograms.
The raw features of speech, waveformslater produced excellent larger-scale results. InLSTM started to become competitive with traditional speech recognizers on certain tasks. Deep learning is part of state-of-the-art systems in various disciplines, particularly computer vision and automatic speech recognition ASR.
The NIPS Workshop on Deep Learning for Speech Recognition  was motivated by the limitations of deep generative models of speech, and the possibility that given more capable hardware and large-scale data sets that deep neural nets DNN might become practical.
It was believed that pre-training DNNs using generative models of deep belief nets DBN would overcome the main difficulties of neural nets.
DNN models, stimulated early industrial investment in deep learning for speech recognition,   eventually leading to pervasive and dominant use in that industry.
That analysis was done with comparable performance less than 1. While there, Ng determined that GPUs could increase the speed of deep-learning systems by about times.

In NovemberCiresan et al. The Wolfram Image Identification project publicized these improvements.PDF | Inpainting, the technique of modifying an image in an undetectable form, is as ancient as art itself.
The goals and applications of inpainting are numerous, from the restoration of damaged. Image Inpainting is a technique which fills the regions that are missing or damaged using the spatial information available in the neighboring region.
Image Inpainting is an ancient method of restoring the images which are damaged due to scratches on it and are old. Image Inpainting is an important research subclass of image.

Students will get involved with a very exciting topic, since image and video inpainting is one of the most used. The Midwest ML Symposium (MMLS) aims to convene regional machine learning researchers for stimulating discussions and debates, to foster cross-institutional collaboration, and to showcase the collective talent of machine learning researchers at all career stages..
