When evaluating the quality of topics generated by a topic model, the convention is to score topic coherence — either manually or automatically — using the top-N topic words. This hyper-parameter N , or the cardinality of the topic, is often overlooked and selected arbitrarily. In this paper, we investigate the impact of this cardinality hyper-parameter on topic coherence evaluation. For two au...

Online music services are increasing in popularity. They enable us to analyze people’s music listening behavior based on play logs. Although it is known that people listen to music based on topic (e.g., rock or jazz), we assume that when a user is addicted to an artist, s/he chooses the artist’s songs regardless of topic. Based on this assumption, in this paper, we propose a probabilistic model...

Abstract Traditionally, submarine hydrodynamic design has focussed mainly on requirements regarding operational range, powering performance and manoeuvring ability for deeply submerged conditions. To improve the effectiveness of boat, attention is also paid to operating near or at surface fortunately, computational tools experimental methods are available analyse submarines these advance hydrod...

This paper proposes methods for determining an appropriate mixing ratio of dialects in automatic speech recognition (ASR) for dialects. To handle ASR for various dialects, it has been reported to be effective to train a language model using a dialectmixed corpus. One reason behind this is geographical continuity of spoken dialect; we regard spoken dialect as a mixture of various dialects. This ...

Considering water scarcity in Iran, application of deficit irrigation or water stress on some crops is inevitable. We need to provide appropriate design for deficit irrigation. Furrow irrigation management to obtain high efficiency and uniformity is difficult. Therefore, to investigate the variation of the input discharge, the cut-off time and furrow length that are effective on the efficiency ...

Abstract:   A two-dimensional fully implicit finite difference model, which can be easily extended to three dimensions, is developed to study the effect of cut-off walls on saltwater intrusion into the aquifers. This model consists of a coupled system of two nonlinear partial differential equations which describe unsteady density-driven groundwater flow and solute transport. The numerica...

Sensing health-related behaviours in an unobtrusive, ubiquitous and cost-effective manner carries significant benefits to healthcare and patient management. In this paper, we focus on detecting typing behaviour that is characteristic of patients suffering from Parkinson’s disease. We consider typing data obtained from subjects with and without Parkinson’s, and we present a framework based on to...

The proper design of a Concentrated solar power (CSP) plant and the associated thermal energy storage requires careful analysis yearly expected irradiance environmental conditions. System simulations based on accurate components models allow prediction performance interactions. various scenarios provide information that will help tuning to improve whole system at off-design In this paper, focus...

راحتی سفر (ride comfort) در خودرو ها بستگی به احساس سرنشیان داخل وسیله نقلیه نسبت به ارتعاشات وارد شده بر خودرو دارد. ارتعاشات بدنه خودرو ناشی از عوامل گوناگونی مثل ناهمواری های سطح جاده، نیروهای آیرودینامیکی، ارتعاشات موتور و نابالانسی چرخ ها می تواند باشد[1].عموما ناهمواری های سطح جاده منبع اصلی ارتعاشات ایجاد شده بر روی وسیله نقلیه بوده و ضربه های اتفاقی ناشی از ناهمواری های جاده، خودرو را د...
