Learning When to Attend for Neural Machine Translation
In the past few years, attention mechanisms have become an indispensable component of end-to-end neural machine translation models. However, previous attention models always refer to some source words when predicting a target word, which contradicts with the fact that some target words have no corresponding source words. Motivated by this observation, we propose a novel attention model that has...
متن کاملLearning to Selectively Attend
How is reinforcement learning possible in a high-dimensional world? Without making any assumptions about the structure of the state space, the amount of data required to effectively learn a value function grows exponentially with the state space’s dimensionality. However, humans learn to solve highdimensional problems much more rapidly than would be expected under this scenario. This suggests t...
متن کاملWhen do pregnant women attend for antenatal care?
The case records of a representative sample of 313 women from four health districts in the North-east Thames Health Region were reviewed to determine the stage of pregnancy at which they contact antenatal services. Patients seeking care (when a blood specimen was obtained) after 20 weeks' gestation ranged from 6% to 26%. These women were more likely to be of higher parity and immigrants. Apprec...
متن کاملCar drivers attend to different gaze targets when negotiating closed vs. open bends.
On winding roads, car drivers have to control speed and steering angle in order to keep the car in an optimal lane position. Among the strategies proposed for steering regulation are the use of the tangent point, a geometrical method, and gaze sampling, in which retinal flow lines obtained by tracking a spot on the future road need to be assessed. Previous studies used a variety of scenarios (r...
متن کاملBilingual and Monolingual Children Attend to Different Cues When Learning New Words
The way in which children learn language can vary depending on their language environment. Previous work suggests that bilingual children may be more sensitive to pragmatic cues from a speaker when learning new words than monolingual children are. On the other hand, monolingual children may rely more heavily on object properties than bilingual children do. In this study we manipulate these two ...
