Movie reviews can be classified as either favorable or not. The evaluation of movie review text is a classification problem often called sentiment analysis. A popular technique for developing sentiment analysis models is to use a bag-of-words model that transforms documents into vectors where each word in the document is assigned a score. In this tutorial, you will discover how you can develop a deep learning predictive model using the bag-of-words representation for movie review sentiment classification.

An updated version of the nation's most authoritative Japanese-language dictionary has added 10,000 new words, including "hanii torappu" (honey trap), "biggu mausu" (big mouth) and "karēshū" (an old person's distinctive smell), the publisher said. The Kojien dictionary was first published in 1955 by Iwanami Shoten with about 200,000 words. Since then it has become a household reference, while media outlets and other high-profile organizations often use it as the final say on a given word's meaning. Other new entries include "apuri" (app), "burakku kigyō" (exploitative firms with bad working conditions), "Isuramu-koku" (Islamic State), "LGBT," "konkatsu" (marriage hunting), "jidori" (selfie) and "diipu rāningu" (deep learning). At its peak, the publisher sold as many as 2.6 million copies of its third edition, which was published in December 1983.

Sony Chief Executive Kazuo Hirai said last year at a strategy briefing that the company was developing "a robot capable of forming an emotional bond with customers, and able to grow to inspire love and affection." He told The Wall Street Journal at the time that the company might make an Aibo-like dog robot. The Nikkei newspaper reported earlier this month that Sony was targeting spring 2018 for the release of a home robot. The robot project is one of Mr. Hirai's initiatives to show that innovation is alive at the Japanese electronics maker, which was known for a string of hits going back to the transistor radio in the 1950s but has more recently focused on shoring up profitability by shrinking its portfolio. More than 100 employees are involved in Sony's robotics projects, said people familiar with them.

TOKUSHIMA – The Tokushima Prefectural Government and e-books distributor Media Do Holdings Co. announced Tuesday they will launch an experiment to use AI to summarize the governor's news conferences in a bid to make more administrative documents available online more quickly. Under the experiment, which they plan to start Monday, they will use a speech recognition system to catch remarks at news conferences given by the governor, and the complete transcription will be posted on the prefectural government's website after being checked by prefecture officials. Users can choose the amount of words they want to read from 10 percent to 90 percent, and AI summarizes the documents in accordance with the users' requests. The new system will reduce the time needed to transcribe news conferences from roughly 10 hours to two hours, and will enable the prefecture to post documents about four hours after the news conferences are held, according to the officials. "Government agencies create a lot of documents but most of them are difficult to read. I hope summarized documents will help people familiarize themselves with the government," said Tokushima Gov. Kamon Iizumi, adding that the move will also help reduce prefectural officials' working hours.

Due to the lack of enough generalization in the state-space, common methods in Reinforcement Learning (RL) suffer from slow learning speed especially in the early learning trials. This paper introduces a model-based method in discrete state-spaces for increasing learning speed in terms of required experience (but not required computational time) by exploiting generalization in the experiences of the subspaces. A subspace is formed by choosing a subset of features in the original state representation (full-space). Generalization and faster learning in a subspace are due to many-to-one mapping of experiences from the full-space to each state in the subspace. Nevertheless, due to inherent perceptual aliasing in the subspaces, the policy suggested by each subspace does not generally converge to the optimal policy. Our approach, called Model Based Learning with Subspaces (MoBLeS), calculates confidence intervals of the estimated Q-values in the full-space and in the subspaces. These confidence intervals are used in the decision making, such that the agent benefits the most from the possible generalization while avoiding from detriment of the perceptual aliasing in the subspaces. Convergence of MoBLeS to the optimal policy is theoretically investigated. Additionally, we show through several experiments that MoBLeS improves the learning speed in the early trials.

Conceptual spaces are geometric representations of conceptual knowledge, in which entities correspond to points, natural properties correspond to convex regions, and the dimensions of the space correspond to salient features. While conceptual spaces enable elegant models of various cognitive phenomena, the lack of automated methods for constructing such representations have so far limited their application in artificial intelligence. To address this issue, we propose a method which learns a vector-space embedding of entities from Wikipedia and constrains this embedding such that entities of the same semantic type are located in some lower-dimensional subspace. We experimentally demonstrate the usefulness of these subspaces as (approximate) conceptual space representations by showing, among others, that important features can be modelled as directions and that natural properties tend to correspond to convex regions.

Michel Fornasier, one of the presenters of the Cybathlon, uses his bionic hand prosthesis to demonstrate one of the Cybathlon disciplines. In the movie Star Wars: The Empire Strikes Back, Luke Skywalker is given a mechanical hand that moves and perform functions as well as his real hand. Konrad Kording, an avid Star Wars fan, has no doubt that advances in brain-machine interfaces (BMIs) will make this bit of science fiction a reality; he just doesn't know when. "We have applications for one channel and a few channels," says Kording, a neuroscientist and professor of Physical Medicine and Rehabilitation, Physiology, and Biomedical Engineering at Northwestern University in Evanston, IL. "The question is, what are the BMI applications with hundreds of thousands of channels, and no one knows that at the moment." The channels he's referring to are electrical wires or optical connectors that can be attached to the brain and can be controlled and measured.

Cambit pieces can be assembled to create a dozen different imaging systems. The cameras in our phones and tablets have turned us all into avid photographers, regularly using them to capture special moments and document our lives. One notable feature of camera phones is they are compact and fully automatic, enabling us to point and shoot without having to adjust any settings. However, when we need to capture photos of high aesthetic quality, we resort to more sophisticated DSLR cameras in which a variety of lenses and flashes can be used interchangeably. This flexibility is important for spanning the entire range of real-world imaging scenarios, while enabling us to be more creative. Many developers have sought to make these cameras even more flexible through both hardware and software.

Special effects that let Hollywood filmmakers remove unwanted objects and people from their final shots could soon be available at the push of a button. Adobe has unveiled a peak of its Cloak project, which enables automatic editing of footage that would take professionals hours to complete. Users of the tool, which is currently under development, can select any item for deletion and smart software fills in the gap. The company has not yet given any word on if or when Cloak will be built into its software. Special effects that let Hollywood filmmakers remove unwanted objects and people from their final shots could soon be available at the push of a button.
