What went wrong? Identification of everyday object manipulation anomalies

چکیده
Enhancing the abilities of service robots is important for expanding what they can achieve in everyday manipulation tasks. In addition, it also essential to ensure that determine cannot achieve. Such necessity may arise due anomalies during task execution. These situations should be detected and identified overcome recover from them. Identification necessitates a deeper time series analysis onboard sensor readings keep track relate anomaly indicators since some perceived long before detection an anomaly. are usually taken asynchronously need fused effectively correct interpretations. this paper, we propose multimodal short-term memory-based (LSTM-based) identification approach takes into account real-time observations by fusing visual, auditory proprioceptive sensory modalities object The symptoms first trained then classified based on learned models real time. We provide comparative our method with hidden Markov (HMMs), conditional random fields (CRFs) gated recurring units (GRUs) Baxter robot executing scenarios. Then, analyze impact each modality various feature extraction techniques performance problem. show has ability identify capturing long-term dependencies between indicators. results indicate LSTM-based outperforms closest baseline 2% improvement f-score (0.92) classifying occur run-time.

What Went Wrong: Explaining Counterexamples
One of the chief advantages of model checking is the production of counterexamples demonstrating that a system does not satisfy a specification. However, it may require a great deal of human effort to extract the essence of an error from even a detailed source-level trace of a failing run. We use an automated method for finding multiple versions of an error (and similar executions that do not p...

that took place in the developing countries in the 1980s and 1990s was part of the general move toward giving markets a greater role in development. It was also a reaction to several factors specific to finance: the costs, corruption, and inefficiencies associated with using finance as an instrument of populist, state-led development; a desire for more financial resources; citizens’ demands for...
متن کاملAgile Development at ABC - What Went Wrong?
Agile development methods continue to enjoy widespread use, with more and more companies transitioning to agile methods. Current literature suggests that most of those companies are successful in making the transition, but others are not so successful. This paper examines one such company – referred to within as the ‘ABC Company’ to maintain their privacy – and analyzes and discusses their stru...
