با توجه به رشد بالای جمعیت در جهان و نیاز اطمینان از امنیت غذایی، افزایش تولید واحد سطح محصولات زراعی به‌منزلة راهبردی اساسی حل مسئلة تأمین غذا به‌شمار می‌رود. سوی دیگر، وجود محدودیت زیرکشت پایین‌بودن میانگین عملکرد برخی کشاورزی مانند گندم کشور، محصول می‌تواند راهکاری عملی پاسخ کشور محسوب شود. یکی مهم‌ترین بیماری‌های فوزاریوم است که، نقش پیش‌بینی این بیماری جلوگیری کاهش بهره‌وری محصول، مدل‌هایی...

Onset of COVID-19 early 2020 disrupted learning in public and private schools Zimbabwe. The traditional face-to-face lesson delivery method was no longer feasible due to lockdowns. purpose this research establish whether or not performance under-resourced affected. compares learners prior during period arts, commercial science subjects. A simple random sampling used collect primary data from ad...

Computer transaction log analysis comprises the modeling of patterns of machine–user transactions. Due to the web-like structure of the Internet, Interactions can be represented in a three-dimensional, origin–destination–time flow/transaction matrix. Loglinear models are used to model these transactions in terms of their time, origin and destination components and to detect the signature and st...

This paper presents a Bayesian approach to learning the connectivity structure of a group of neurons from data on configuration frequencies. A major objective of the research is to provide statistical tools for detecting changes in firing patterns with changing stimuli. Our framework is not restricted to the well-understood case of pair interactions, but generalizes the Boltzmann machine model ...

In Bayesian analysis of multi-way contingency tables, the selection of a prior distribution for either the log-linear parameters or the cell probabilities parameters is a major challenge. In this paper, we define a flexible family of conjugate priors for the wide class of discrete hierarchical log-linear models, which includes the class of graphical models. These priors are defined as the Diaco...

A marketplace such as Amazon hosts many products by third party sellers and acts a first or private label retailer. Assuming an advantage of in logistics marketing, we investigate whether entry is excessive from the point view consumers. With competitive sellers, may be either overprovided underprovided, but incentives consumers are correctly aligned for family power surplus functions (generati...

The Microsoft Research translation system is a syntactically informed phrasal SMT system that uses a phrase translation model based on dependency treelets and a global reordering model based on the source dependency tree. These models are combined with several other knowledge sources in a log-linear manner. The weights of the individual components in the loglinear model are set by an automatic ...

This paper reports some experiments that compare the accuracy and performance of two stochastic parsing systems. The currently popular Collins parser is a shallow parser whose output contains more detailed semanticallyrelevant information than other such parsers. The XLE parser is a deep-parsing system that couples a Lexical Functional Grammar to a loglinear disambiguation component and provide...

Loglinear modeling methods have become quite straightforward to apply to discrete data X. The models for missing data involve minor extensions of hot-deck methods (Little and Rubin 2002). Edits are structural zeros that forbid certain patterns. Winkler (2003) provided the theory for connecting edit with imputation. In this paper, we give methods and algorithms for modeling/edit/imputation under...
