Large Language Models (LLMs) are evolving rapidly on code generation tasks. While it is important to evaluate their code generation accuracy, ensuring they follow responsible practices is equally critical. Some of the previous works use tools such as CodeQL to match patterns against Common Weakness Enumeration (CWE), suffering from high error rate, while others rely on human annotation to only focus on top CWE categories, limiting security coverage. We propose AutoSUIT Bench, which addresses these limitations through a paradigm to automate the vulnerable code benchmark creation with iterative auto validation. As a result, our benchmark covers 232 CWE categories across C/C++, Java, and Python languages and is designed to evaluate on four coding tasks: (i) code generation, (ii) generation with CWE context, (iii) security patching, and (iv) code completion. Upon benchmarking against LLMs, we found that functionality pass rate is consistently higher than vulnerability pass rate for all programming languages. One notable observation from our benchmark is that LLMs perform well on top CWEs while lacks on others down the list. This highlights the necessity of vulnerable code benchmarks with larger CWE coverage.

Multimodal affective computing, learning to recognize and interpret human affect and subjective information from multiple data sources, is still a challenge because: (i) it is hard to extract informative features to represent human affects from heterogeneous inputs; (ii) current fusion strategies only fuse different modalities at abstract levels, ignoring time-dependent interactions between modalities. Addressing such issues, we introduce a hierarchical multimodal architecture with attention and word-level fusion to classify utterance-level sentiment and emotion from text and audio data. Our introduced model outperforms state-of-the-art approaches on published datasets, and we demonstrate that our model is able to visualize and interpret synchronized attention over modalities.

We examine the utility of linguistic content and vocal characteristics for multimodal deep learning in human spoken language understanding. We present a deep multimodal network with both feature attention and modality attention to classify utterance-level speech data. The proposed hybrid attention architecture helps the system focus on learning informative representations for both modality-specific feature extraction and model fusion. The experimental results show that our system achieves state-of-the-art or competitive results on three published multimodal datasets. We also demonstrated the effectiveness and generalization of our system on a medical speech dataset from an actual trauma scenario. Furthermore, we provided a detailed comparison and analysis of traditional approaches and deep learning methods on both feature extraction and fusion.
