Background Nonalcoholic fatty liver disease (NAFLD) is a common digestive system disease, which is often diagnosed by imaging methods in clinical work. At present, there is a lack of research on the effectiveness evaluation of imaging diagnostic meth

Data from multiple environments offer valuable opportunities to uncover causal relationships among variables. Leveraging the assumption that the causal outcome model remains invariant across heterogeneous environments, state-of-the-art methods attemp

Visual Text-to-Speech (VTTS) aims to take the environmental image as the prompt to synthesize the reverberant speech for the spoken content. The challenge of this task lies in understanding the spatial environment from the image. Many attempts have b

Heteroscedasticity and correlated data pose challenges for extreme value analysis, particularly in two-sample testing problems for tail behaviors. In this paper, we propose a novel copula-based multivariate model for independent but not identically d

A partition is finitary if all its blocks are finite. For a cardinal $\mathfrak{a}$ and a natural number $n$, let $\mathrm{fin}(\mathfrak{a})$ and $\mathscr{B}_{n}(\mathfrak{a})$ be the cardinalities of the set of finite subsets and the set of finita

Based on the actual engineering development experience, the working principle of the roll-pitch semi-strapdown guidance system is analyzed. Focused on the influence of disturbance rejection on the miss distance of the guidance loop, the roll-pitch se

Conversational Text-to-Speech (CTTS) aims to accurately express an utterance with the appropriate style within a conversational setting, which attracts more attention nowadays. While recognizing the significance of the CTTS task, prior studies have n

Non-stationarity poses significant challenges for multivariate time series forecasting due to the inherent short-term fluctuations and long-term trends that can lead to spurious regressions or obscure essential long-term relationships. Most existing

As financial markets grow increasingly complex in the big data era, accurate stock prediction has become more critical. Traditional time series models, such as GRUs, have been widely used but often struggle to capture the intricate nonlinear dynamics

Policy gradient methods are widely used in reinforcement learning. Yet, the nonconvexity of policy optimization imposes significant challenges in understanding the global convergence of policy gradient methods. For a class of finite-horizon Markov De
