4 hours agoOverview. The term one-class classification (OCC) was coined by Moya & Hush (1996) and many applications can be found in scientific literature, for example outlier detection, anomaly detection, novelty detection.A feature of OCC is that it uses only sample points from the assigned class, so that a representative sampling is not strictly required for non-target classes.

Industrial document classification with Deep Learning

12.29.2359 hours ago

1. OCTO’s knowledge base gathers more than 1,5 million slides. It is daily fed with new documents that consultants create to illustrate ideas for our clients. To prepare the dataset, we started by interviewing some of our consultants to identify classes with high value to the company. Each class corresponds to a distinct typology of slide that has a real usefulness to our core business. We considered that each slide can be associated with only one class. After that, we started labeling the dataset documents. However, because the manual labeling can be very tedious, we developed a web application to speed up the process. But one problem remained: how to recognize the slides that do not belong to any of the identified classes? One idea we had was to group the remaining classes in a new class « Other ». The final dataset is composed of 6 different classes with 500 samples each (3000 slides in total).

Approximately 85000 such questions have been published as a dataset on kaggle.com.Given this dataset we trained a Keras model which predicts keywords for new questions. The 85000 questions are labelled with a total of approximately 244000 labels. There are 1315 unique tags in this dataset.

Top 10 Deep Learning Algorithms You Should Know in 2021

4 hours ago

1. Convolutional Neural Networks (CNNs) CNN's, also known as ConvNets, consist of multiple layers and are mainly used for image processing and object detection.
2. Long Short Term Memory Networks (LSTMs) LSTMs are a type of Recurrent Neural Network (RNN) that can learn and memorize long-term dependencies. Recalling past information for long periods is the default behavior.
3. Recurrent Neural Networks (RNNs) RNNs have connections that form directed cycles, which allow the outputs from the LSTM to be fed as inputs to the current phase.
4. Generative Adversarial Networks (GANs) GANs are generative deep learning algorithms that create new data instances that resemble the training data. GAN has two components: a generator, which learns to generate fake data, and a discriminator, which learns from that false information.
5. Radial Basis Function Networks (RBFNs) RBFNs are special types of feedforward neural networks that use radial basis functions as activation functions.
6. Multilayer Perceptrons (MLPs) MLPs are an excellent place to start learning about deep learning technology. MLPs belong to the class of feedforward neural networks with multiple layers of perceptrons that have activation functions.
7. Self Organizing Maps (SOMs) Professor Teuvo Kohonen invented SOMs, which enable data visualization to reduce the dimensions of data through self-organizing artificial neural networks.
8. Deep Belief Networks (DBNs) DBNs are generative models that consist of multiple layers of stochastic, latent variables. The latent variables have binary values and are often called hidden units.
9. Restricted Boltzmann Machines (RBMs) Developed by Geoffrey Hinton, RBMs are stochastic neural networks that can learn from a probability distribution over a set of inputs.
10. Autoencoders. Autoencoders are a specific type of feedforward neural network in which the input and output are identical. Geoffrey Hinton designed autoencoders in the 1980s to solve unsupervised learning problems.

Python for NLP: Multilabel Text Classification with Keras

1 hours ago

1. This is the 19th article in my series of articles on Python for NLP. From the last few articles, we have been exploring fairly advanced NLP concepts based on deep learning techniques. In the last article, we saw how to create a text classification model trained using multiple inputs of varying data types. We developed a text sentiment predictor using textual inputs plus meta information. In this article, we will see how to develop a text classification model with multiple outputs. We will be developing a text classification model that analyzes a textual comment and predicts multiple labels associated with the comment. The multi-label classification problem is actually a subset of multiple output model. At the end of this article you will be able to perform multi-label text classification on your data. The approach explained in this article can be extended to perform general multi-label classification. For instance you can solve a classification problem where you have an image as inp...
