The authors propose a new methodology for creating the first automatically adapting learning rates that achieve optimal rate of convergence stochastic gradient descent. Empirical tests agree with theoretical expectations drift can be used to determine whether crucial parameter c is large enough. Using this statistic, it will possible produce adaptive which converge at speed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>

Information technology (IT) programs are collections of projects structured to meet goals established by top management regarding the use technology. Prior research has importance commitment organizational set and a shared understanding among project teams. However, conflicts occur teams due pursuit their own goals, unique approaches completion required tasks, individual need for limited resources. These be resolved in fashion that leads program not independent lodged projects. We develop...

Leadership must be leveraged at the management level to develop capabilities needed succeed in digital transformation projects, where complications arise due technological novelty and environmental dynamics. Transformational leadership (TRL) adaptive (ADL) are proposed as successful approaches for managing changing behaviors faster adaptation new circumstances. Survey results demonstrate positive influence of TRL on three project dynamic capabilities. However, its impact capability is weak....

In this paper, a Takagi-Sugeno-Kang (TSK) type collaborative fuzzy rule based system is proposed with the help of knowledge learning ability clustering (CFC). The method split huge dataset into several small datasets and applying mechanism to interact each other process could be helpful solve big data issue. applies collective CFC as input variables consequent part linear combination variables. Through intensive experimental tests on prediction problem, performance higher methods. only uses...

In this paper, a new technique for the Chinese text-to-speech (TTS) system is proposed. Our major effort focuses on prosodic information generation. New methodologies constructing fuzzy rules in model simulating human's pronouncing are developed. The proposed Recurrent Fuzzy Neural Network (RFNN) multilayer recurrent neural network (RNN) which integrates Self-cOnstructing Inference (SONFIN) into connectionist structure. RFNN can be functionally divided two parts. first part adopts SONFIN as...

Background: Firms recently rely on enterprise systems, such as resource planning (ERP), to integrate, automate, and support business strategy operations. However, uncertain environments require firms continuously adapt their ERP systems meet changing demands in the post-implementation stage. What capability can drive adaptation (PIA) deserves further research. Based dynamic capabilities view, we propose that IT for ERP, namely sensing, learning, integration, coordination capability, ERP-PIA.

To achieve desired business benefits from the implementation of an enterprise system (ES), current practitioners often adopt a multiple-project (program) approach instead conventional single-project strategy. Unfortunately, during such implementation, issues arising task-related conflicts among different teams within ES program are frequently observed; to successfully resolve these task-conflict issues, adoption collaborative problem-solving strategy is essential. Collaborative conflict...

During the implementation of IT programs, competition among project managers for scarce resources required completion individual projects is a common phenomenon. To avoid such self-interested resource managers, according to agency theory, monitoring can serve as an effective management mechanism conflict resolution within program. Furthermore, team cognition theory suggests that understanding goals each also solid foundation monitoring. Social interdependence positive goal program motivate...

Learning is a fundamental aspect of innovative new product development (NPD), and research shows that failures are source learning in NPD programs. However, little known about the role from successful experiences. We develop model for both success failure, based on characteristics multiteam systems (MTS) complexity. Quantitative analysis 167 programs organized as MTS suggests crucial innovation at all levels complexity, while effectiveness failure diminishes with increasing Qualitative...

The dynamics of the market pose a challenge for digital game industry. Game development firms must develop innovative games to satisfy players’ ever-changing needs and sustain suitable product/market fit. To realize such innovation, developers tend adopt an ambidextrous approach that includes exploratory exploitative activities games. In addition, teams rely on feedback from testers enhance meet needs. However, effect innovation is subject debate. Some studies have proposed has potentially...

The Software-as-a-Service (SaaS) product model provides clients to outsource software application processing requirements. Customer satisfaction is an important problem facing SaaS firms. Marketing theory suggests that customer affected by perceived value, but this relationship has not been examined in the context. This study argues for mediating role of value between traits and satisfaction. Our builds on prior studies success theories consider whether service quality, response, security,...
