To transcribe spoken language to written medium, most alphabets enable an unambiguous sound-to-letter rule. However, some writing systems have distanced themselves from this simple concept and little work exists in Natural Language Processing (NLP) on measuring such distance. In this study, we use an Artificial Neural Network (ANN) model to evaluate the transparency between written words and their pronunciation, hence its name Orthographic Transparency Estimation with an ANN (OTEANN). Based on datasets derived from Wikimedia dictionaries, we trained and tested this model to score the percentage of false predictions in phoneme-to-grapheme and grapheme-to-phoneme translation tasks. The scores obtained on 17 orthographies were in line with the estimations of other studies. Interestingly, the model also provided insight into typical mistakes made by learners who only consider the phonemic rule in reading and writing.

The evaporation is one of the basic components of the hydrologic cycle and it is essential for studies such as water balance, irrigation system design and water resource management, and it requires knowledge of many climatic variables. Although, th ere are many empirical formulas available for evaporation estimate, but their performances are not all satisfactory due to the complicated nature of the evaporation process. Accordingly, this paper is an attempt to assess the potential and usefulness of ANN based modeling for evaporation prediction from HAMA by using temperature, relative humidity and wind velocity. The mathematical model was built by the (nntool-box), which is one of the MATLAB tools. The feed forward back propagation network with one hidden layer has been utilised to construct the model. Different networks with different number of neurons were evaluated. Root Mean Squared Error (RMSE) was employed to evaluate the accuracy of the proposed model. The study shows that ANN (3-14-1) was the best model with RMSE (21.5mm/month) and R2 (0.97). This study suggests using other types of neural networks for estimation of evaporation
This study includes the possibility of using Artificial neural networks (ANNs) with back-propagation algorithm in a short-term prediction of water level in Qattinah Lake. The data used are the water level data in the lake and rainfall data for the period from 1/5/2007 to 28/2/2005. 2009).
The purpose of this article is to shed light on the mechanism and the procedures of a program that classifies an input face into any of the six basic facial expressions, which are Anger, Disgust, Fear, Happiness, Sadness and Surprise, in addition to normal face. This program works by apply PCA- principal component analysis algorithm, which is applied of one side of the face, and depends, on contrast to the traditional studies which rely on the whole face, on three components: Eyebrows, Eyes and Mouth. Those out-value are used to determine the facial feature array as an input to the neural network, and the neural network is trained by using the back-propagation algorithm. Note that the faces used in this study belong to people from different ages and races.
Rainfall is highly non-linear and complicated phenomena, which require nonlinear mathematical modeling and simulation for accurate prediction. This study comparing the performance of the prediction of one-day-ahead, where Two Feed Forward Neural N etwork FFNN models were developed and implemented to predict the rainfall on daily for three months (December, January, February). These models are Artificial Neural Network traditional (ANN) model and artificial neural network technique combined with wavelet decomposition (Wavelet- Neural) According to two different methods to build a model using two types of wavelets of Daubechies family (db2, db5). In order to compare the performance of the models in their ability to predict the rains on short-term (for one and two and three-days-ahead) the last months of the period of study, used some statistical standards, These parameters include the Root Mean Square Error RMSE, Coefficient Of Correlation (R).
Emotion recognition in multi-party conversation (ERMC) is becoming increasingly popular as an emerging research topic in natural language processing. Prior research focuses on exploring sequential information but ignores the discourse structures of c onversations. In this paper, we investigate the importance of discourse structures in handling informative contextual cues and speaker-specific features for ERMC. To this end, we propose a discourse-aware graph neural network (ERMC-DisGCN) for ERMC. In particular, we design a relational convolution to lever the self-speaker dependency of interlocutors to propagate contextual information. Furthermore, we exploit a gated convolution to select more informative cues for ERMC from dependent utterances. The experimental results show our method outperforms multiple baselines, illustrating that discourse structures are of great value to ERMC.
