Abstract
This paper presents semantics, syntax, and tools for specification and verification of safety and liveness properties of behavioral programs. Verification is performed directly on program code, by traversing its transition system. Liveness properties are defined using “hot states”, in which scenarios are allowed to stay for a finite time, but not forever. Safety properties are defined using assertions which allow labeling program states as having violations, and by analyzing program states for deadlocks detection. The paper defines liveness violations with regards to specific program components and describes an approach for validating the absence of such violations is a system. The proposed approach is supported by BPjs, an open-source tool suite developed by the authors.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
