Retrieval–travel-time model for free-fall-flow-rack automated storage and retrieval system
Automated storage and retrieval systems (AS/RSs) are material handling systems that are frequently used in manufacturing and distribution centers. The modelling of the retrieval–travel time of an AS/RS (expected product delivery time) is practically important, because it allows us to evaluate and improve the system throughput. The free-fall-flow-rack AS/RS has emerged as a new technology for dr...
متن کاملEnsemble Learning For Machine Comprehension: Bidirectional Attention Flow Models
In this paper, we will explore machine comprehension in Stanford Question and Answering Dataset using ensembled deep recurrent neural networks with bi-directional attention flow. Given a context paragraph, we attempt to answer a query related to the context paragraph. This requires use to not only generate knowledge representation for each question and paragraph, but also create mechanisms that...
متن کاملthe application of multivariate probit models for conditional claim-types (the case study of iranian car insurance industry)
هدف اصلی نرخ گذاری بیمه ای تعیین نرخ عادلانه و منطقی از دیدگاه بیمه گر و بیمه گذار است. تعین نرخ یکی از مهم ترین مسایلی است که شرکتهای بیمه با آن روبرو هستند، زیرا تعیین نرخ اصلی ترین عامل در رقابت بین شرکتها است. برای تعیین حق بیمه ابتدا می باید مقدار مورد انتظار ادعای خسارت برای هر قرارداد بیمه را برآورد کرد. روش عمومی مدل سازی خسارتهای عملیاتی در نظر گرفتن تواتر و شدت خسارتها می باشد. اگر شر...
15 صفحه اولBidirectional Learning for Time-series Models with Hidden Units
Hidden units can play essential roles in modeling time-series having long-term dependency or nonlinearity but make it difficult to learn associated parameters. Here we propose a way to learn such a time-series model by training a backward model for the time-reversed time-series, where the backward model has a common set of parameters as the original (forward) model. Our key observation is that ...
متن کاملOn Stacking Probabilistic Temporal Models with Bidirectional Information Flow
We discuss hierarchical combinations of probabilistic models where the upper layer is crafted for predicting time-series data. The combination of models makes the naı̈ve Bayes assumption, stating that the latent variables of the models are independent given the time-indexed label variables. In this setting an additional independence assumption between time steps and mildly inconsistent results a...
