  • Automation, the use of robots in industry, has not progressed with the speed that many had hoped it would. The forecasts of twenty years ago are looking fairly silly today: the fact that they were produced largely by journalists for the benefit of boardrooms of accountants and MBA's may have something to do with this, but the question of why so little has been accomplished remains.

  • This lecture introduces you to the fascinating subject of classification and regression with artificial neural networks. In particular, it introduces multi-layer perceptrons (MLPs); teaches you how to combine probability with neural networks so that the nets can be applied to regression, binary classification and multivariate classification; discusses the modular approach to backpropagation and neural network construction in Torch, which was introduced in the previous lecture.

  • In this paper, we present a model-based learning for brain tumour segmentation from multimodal MRI protocols. The model uses U-Net-based fully convolutional networks to extract features from a multimodal MRI training dataset and then applies them to Extremely randomized trees (ExtraTrees) classifier for segmenting the abnormal tissues associated with brain tumour. The morphological filters are then utilized to remove the misclassified labels. Our method was evaluated on the Brain Tumour Segmentation Challenge 2013 (BRATS 2013) dataset, achieving the Dice metric of 0.85, 0.81 and 0.

  • Automatic segmentation and localization of lesions in mammogram (MG) images are challenging even with employing advanced methods such as deep learning (DL) methods. We developed a new model based on the architecture of the semantic segmentation U-Net model to precisely segment mass lesions in MG images.

  • This paper presents a method for inducing the parts of speech of a language and partof-speech labels for individual words from a large text corpus. Vector representations for the part-of-speech of a word are formed from entries of its near lexical neighbors. A dimensionality reduction creates a space representing the syntactic categories of unambiguous words. A neural net trained on these spatial representations classifies individual contexts of occurrence of ambiguous words. The method classifies both ambiguous and unambiguous words correctly with high accuracy. ...
