This paper focuses on intersemiotic translation of Yixiang, or image in western literary term, from poetry to painting by taking Tang Poetry in Paintings as a case to exemplify the translation strategies of Yixiang from verbal sign system to visual sign system. Furthermore, the meditative role of the visualized images in the target context will also be touched upon. A qualitative approach is applied in the study. Typical examples will be chosen for case analysis. It is found that the strategies of equivalence, focalization, integration, montage, addition, contrast and omission are employed by the painters. The effects of those visualized images varied in different cases. Overall, cooperating with the interlingual translations, visual languages such as color, shadow, body language of figures, picture structure are employed to help English readers better receive the poems.

Kazakhstan is recently experiencing an increase in drought trends. However, low-capacity probabilistic drought forecasts and poor dissemination have led to a drought crisis in 2021 that resulted in the loss of thousands of livestock. To improve drought forecasting accuracy, this study applies Machine Learning and Deep Learning (ML and DL) algorithms to capture the sequences of drought events using a non-contiguous drought analysis (NCDA). Precipitation, 2-m temperature, runoff, solar radiation, relative humidity, and evaporation were collected from the ERA5 database as input variables. Combinations of inputs were used to build ML models, including seven classifiers (Logistic, K-NN, Kernel SVM, Decision Tree, Random Forest, XGBoost, and GRU). The output events were defined by standardized precipitation index (SPI) and SPEI indicators as binary classes. Weekly time series from 1991 to 2021 for each cell were used to forecast a lead time from 1 week to 6 months. GRU provided 97–99% accuracy in more volatile regions while Random Forest and XGBoost showed 94–99% accuracy at a lead time of 6 months. The accuracy evaluation was based on the confusion matrix and F1 score to analyze the stage change capture. This study demonstrates the effectiveness of using ML and DL algorithms for drought forecasting, with potential applications for other regions.
