With advancements in deep learning, neural simulators have become increasingly important for improving the efficiency and effectiveness of simulating complex dynamical systems in various scientific and technological fields. This paper presents a novel neural simulator called Context-informed Polymorphic Neural ODE Processes (CoPoNDP), aimed at addressing the challenges of modeling dynamical systems encountering concurrent environmental and temporal distribution shifts, which are common in real-world scenarios. CoPoNDP employs a context-driven neural stochastic process governed by a combination of basic differential equations in a time-sensitive manner to adaptively modulate the evolution of system states. This allows for flexible adaptation to changing temporal dynamics and generalization across different environments. Extensive experiments conducted on dynamical systems from ecology, chemistry, physics, and energy demonstrate that by effectively utilizing contextual information, CoPoNDP outperforms the state-of-the-art models in handling joint distribution shifts. It also shows robustness in sparse and noisy settings, making it a promising approach for modeling dynamical systems in complex real-world applications.

Computer Graphics is an important course for graduate students in computer major. Aiming at the present teaching situation of computer graphics course, combined with an the course characteristics, some educational reform measures, such as adjusting of teaching content, employing more examples in teaching, strengthening the combination of knowledge and practical ability, was proposed. The teaching practices show that these methods can arouse students' learning interest, make the students understand the course better, and obviously improve the quality of teaching.

Based on an analysis of the present teaching situation of Digital Logic course in higher school, this paper points out its existing problems, discusses some key issues and then proposes the ideas such as bringing modern design methodology into course teaching, conducting hierarchical textbooks construction, employing different teaching method and teaching content for different teaching objectives and intensifying the combination of textbook and engineering practical use, so as to improve teaching effectiveness, develop students' interest and enhance their comprehensive practical ability. As the coping strategy to deal with the existing problems of Digital Logic course in higher education, this method has already made certain achievements in both teaching and experiment.
