Deeply Moving: Deep Learning for Sentiment Analysis

@machinelearnbot

Recursive Deep Models for Semantic Compositionality Over a Sentiment Treebank Semantic word spaces have been very useful but cannot express the meaning of longer phrases in a principled way. Further progress towards understanding compositionality in tasks such as sentiment detection requires richer supervised training and evaluation resources and more powerful models of composition. To remedy this, we introduce a Sentiment Treebank. It includes fine grained sentiment labels for 215,154 phrases in the parse trees of 11,855 sentences and presents new challenges for sentiment compositionality. To address them, we introduce the Recursive Neural Tensor Network.


Semi-supervised Convolutional Neural Networks for Text Categorization via Region Embedding

Neural Information Processing Systems

This paper presents a new semi-supervised framework with convolutional neural networks (CNNs) for text categorization. Unlike the previous approaches that rely on word embeddings, our method learns embeddings of small text regions from unlabeled data for integration into a supervised CNN. The proposed scheme for embedding learning is based on the idea of two-view semi-supervised learning, which is intended to be useful for the task of interest even though the training is done on unlabeled data. Our models achieve better results than previous approaches on sentiment classification and topic classification tasks. Papers published at the Neural Information Processing Systems Conference.


Developing a NLP based PR platform for the Canadian Elections

#artificialintelligence

Elections are a vital part of democracy allowing people to vote for the candidate they think can best lead the country. A candidate's campaign aims to demonstrate to the public why they think they are the best choice. However, in this age of constant media coverage and digital communications, the candidate is scrutinized at every step. A single misquote or negative news about a candidate can be the difference between him winning or losing the election. It becomes crucial to have a public relations manager who can guide and direct the candidate's campaign by prioritizing specific campaign activities. One critical aspect of the PR manager's work is to understand the public perception of their candidate and improve public sentiment about the candidate.


Machine Learning: Classification Models – Fuzz – Medium

#artificialintelligence

These days the terms "AI", "Machine Learning", "Deep Learning" are thrown around by companies in every industry, they're the type of words that make any forward-looking executive salivate. You might think these are new concepts that seemed to have appeared overnight, but the reality is they've been around for a while and it's the hard work of many within the field that has really moved it into the spotlight as the latest tech trend. While these terms are sometimes used interchangeably by the media they certainly are not the same, but I'll leave that discussion for another time.


DeepFake -- trending topic in the news today - WebSystemer.no

#artificialintelligence

DeepFakes are created by a deep learning technique known as Generative Adversarial Networks (GANs), where two machine learning models are used to make the counterfeits more believable. By studying the images and videos of a person, in the form of training data, the first model creates a video, while the second model attempts to detect its flaws. These two models work hand-in-hand until they create a video that is believable. DeepFake opens up a whole new world when it comes to unsupervised learning, which is a sub-field of machine learning where machines can learn to teach themselves, and it has been argued to hold great promise when it comes to self-driving vehicles' to detect and recognize obstacles on the road and virtual assistants such as Siri, Cortana and Alexa learning to be more conversational. The real question is, what potential does it have of being misused, like any other technology.
