Recently, sentiment analysis has seen remarkable advance with the help of pre-training approaches. However, knowledge, such as words and aspect-sentiment pairs, is ignored in process pre-training, despite fact that they are widely used traditional In this paper, we introduce Sentiment Knowledge Enhanced Pre-training (SKEP) order to learn a unified representation for multiple tasks. With automatically-mined SKEP conducts masking constructs three knowledge prediction objectives, so embed...
Reward shaping is an effective technique for incorporating domain knowledge into reinforcement learning (RL). Existing approaches such as potential-based reward normally make full use of a given function. However, since the transformation human numeric values often imperfect due to reasons cognitive bias, completely utilizing function may fail improve performance RL algorithms. In this paper, we consider problem adaptively We formulate utilization rewards bi-level optimization problem, where...

Understanding user instructions in natural language is an active research topic AI and robotics. Typically, are high-level can be reduced into low-level tasks expressed common verbs (e.g., `take', `get', `put'). For robots understanding such instructions, one of the key challenges to process achieve specified with robots' primitive actions. To address this, we propose novel algorithms by utilizing semantic roles defined dictionaries integrating multiple open knowledge generate task plans....
Offline reinforcement learning (RL) provides a promising approach to avoid costly online interaction with the real environment. However, performance of offline RL highly depends on quality datasets, which may cause extrapolation error in process. In many robotic applications, an inaccurate simulator is often available. data directly collected from cannot be used due well-known exploration-exploitation dilemma and dynamic gap between simulation To address these issues, we propose novel...
The bond behavior between the textile and earth-based matrix determined reinforcement effectiveness of composite systems. This paper presented a pull-out experimental study on glass mesh reinforced matrix. was studied using different development length, spacing size thickness, with total 32 specimens. test results showed that peak force had increased by 31.7% 40.5% 200 mm 300 versus 100 respectively. 16 compared to 10 thickness specimens high strength improvement (9.73%) because elevated...
Aiming at the characteristics of forming difficulty for Semimonocoque, a finite element analysis on precision forging was conducted by using rigid-plastic method based DEFORM-3D software. The metal flow law during process studied. equivalent stress, strain distribution and load-stroke curve were analyzed. numerical simulation results used to optimize die structure technological parameters. research verified valid experiment.
An adjustable foaming machine that consisted of air feeding system, liquid device, and control system was designed to satisfy various demands on foam density diameter in the preparation concrete. The air-liquid ratio adjusted by controlling flow, adjustment achieved. single-foam tube structure adopted realize controls pore size adjusting packing medium tube. By using single chip as digital processing core, communication between frequency converter established through RS485 interface, thereby...
This paper describes MDS: a Multimodal-based Dialog System that supports communication between the hearing impaired and hearing-abled. The system converts sign language to speech, combines speech with gesture lip motion using human face. features of face are derived by doing 3D feature extraction speaker's face, so "virtual face" similar actual speaker. main technologies associated include recognition, synthesis synchrony movement speech. Integration synthesis, virtual provides new way...
We propose a system, named ATVHunter, which can pinpoint the precise vulnerable in-app TPL versions and provide detailed information about vulnerabilities TPLs. two-phase detection approach to identify specific versions. Specifically, we extract Control Flow Graphs as coarse-grained feature match potential TPLs in pre-defined database, then opcode each basic block of CFG fine-grained exact build comprehensive database (189,545 unique with 3,006,676 versions) reference database. Meanwhile,...
