Abstract: Described herein are systems and methods for compressing or otherwise reducing the memory requirements for storing and computing the model parameters in recurrent neural language models. Embodiments include space compression methodologies that share the structured parameters at the input embedding layer, the output embedding layers, or both of a recurrent neural language model to significantly reduce the size of model parameters, but still compactly represent the original input and output embedding layers. Embodiments of the methodology are easy to implement and tune. Experiments on several data sets show that embodiments achieved similar perplexity and BLEU score results while only using a fraction of the parameters.

Abstract: A hand-held cutting tool includes a cutting member, a motor, a housing, a baseplate, a drive shaft, a transmission device and a shield. The motor has an output shaft rotating around a first axis. The housing is provided with a handle portion. The baseplate having a supporting surface connects to the housing and is rotatable about a second axis. The drive shaft drives the cutting member to rotate around a third axis perpendicular to the first axis. The shield encloses at least in part the cutting member in a circumferential direction of the third axis. The first axis obliquely intersects the supporting surface. The supporting surface is parallel to the third axis. The shield and the handle portion are disposed on a same side of the supporting surface. The second axis is parallel to the third axis.

Abstract: The present invention provides a fibrous IM-5 molecular sieve and the preparation process thereof. According to the process according to the present invention, by adding an appropriate amount of a quaternary ammonium salt with a long carbon chain to the preparation system so as to occur a synergistic action with the organic templet agent, an IM-5 molecular sieve which would be otherwise a rodlike form is converted into the fibrous form. The IM-5 molecular sieve according to the present invention has an aspect ratio greater than that of the rodlike IM-5 molecular sieve obtained according to the prior art, such that the proportion of the exposed periphery crystal face is higher, which benefit to increasing the selectivity of the catalytic reaction for the corresponding crystal face.

Abstract: The present invention provides a hollow IM-5 molecular sieve sphere and the preparation process thereof. The process according to the present invention adds a relatively great amount of the surfactant of a cationic quaternary ammonium salt in the IM-5 molecular sieve system, to form a hollow IM-5 molecular sieve sphere via the micelle action by the surfactant, which structure benefits the mass transfer of the reaction process.

Abstract: A guiding mechanism for an electric tool includes at least two guiding elements at least one of which has a first end portion having at least one protruding portion extending outwards therefrom and the other of which has a second end portion having at least one groove therein which may be engaged with the protruding portion. The groove has a cut-out and the protruding portion has an elastic clamping portion which may be engaged with the cut-out.

Abstract: A composite language model may include a composite word predictor. The composite word predictor may include a first language model and a second language model that are combined according to a directed Markov random field. The composite word predictor can predict a next word based upon a first set of contexts and a second set of contexts. The first language model may include a first word predictor that is dependent upon the first set of contexts. The second language model may include a second word predictor that is dependent upon the second set of contexts. Composite model parameters can be determined by multiple iterations of a convergent N-best list approximate Expectation-Maximization algorithm and a follow-up Expectation-Maximization algorithm applied in sequence, wherein the convergent N-best list approximate Expectation-Maximization algorithm and the follow-up Expectation-Maximization algorithm extracts the first set of contexts and the second set of contexts from a training corpus.
