What is simple? How can we make simple things? Simplicity seems easy to grasp but is surprisingly difficult to explain. “We know it when we see it”, but we don’t know how to describe it. This essay reflects on a number of observations about simplicity ...

Discovering simple, understandable and yet accurate process models is a well-known issue for models mined from real-life event logs. In this paper, we consider algorithms for automatically computing nested groups of activities in declarative ...

This article unifies and generalizes fundamental results related to n-process asynchronous crash-prone distributed computing. More precisely, it proves that for every $0\le k\le n$, assuming that process failures occur only before the number of ...$$$$$\mathrm{}$$$

This research project was carried out in Indonesia and focuses on how top management support affects the adoption of information systems in the banking sector. With 76 respondents, the study used a questionnaire-based methodology. Structural Equation ...

Although process model discovery has been largely investigated over the past two decades, existing process discovery methods are not yet considered fully satisfactory. A particular issue is the difficulty of discovering process models with a good ...

Probabilistic linear discriminant analysis (PLDA) is widely implemented in speaker verification tasks. However, PLDA has limitations owing to its assumptions. In this study, we explore how to make deep speaker embeddings suitable for ...

• We investigate how to make embeddings suitable for PLDA.
• We analyze the effect ...

We consider the problem of truthfully auctioning a single item, that can be either fractionally or probabilistically divided among several winners when their bids are sufficiently close to a tie.

While Myerson’s Lemma states that any monotone ...

The convolutional neural network is a deep learning architecture that has dominated most computer vision tasks for several years. But starting from 2020, Transformer architecture has turned to be a new challenger that has been expected to replace ...

It is almost always easier to find an accurate-but-complex model than an accurate-yet-simple model. Finding optimal, sparse, accurate models of various forms (linear models with integer coefficients, decision sets, rule lists, decision trees) is ...

The idea that “simplicity is a sign of truth”, and the related “Occam’s razor” principle, stating that, all other things being equal, simpler models should be preferred to more complex ones, have been long discussed in philosophy and science. We ...

This research aims to ascertain how to effectively mitigate privacy risks in IoT devices. A user-centric approach is employed to increase user control and flexibility. After a detailed analysis of the extant literature, critical success factors ...

The problem of blind joint FIR-MIMO channel and data estimation is addressed in this paper. Based on a regularized DML (Deterministic Maximum Likelihood) formulation of the problem, a bilinear approach is used in order to estimate ...

• In this paper, we provide a formal definition of a causal broadcast abstraction in the presence of Byzantine processes.

Causal broadcast is a communication abstraction built on top of point-to-point send/receive networks that ensures that any two messages whose broadcasts are causally related (as captured by Lamport's “happened before” relation) are ...

Algorithms are increasingly used to aid, or in some cases supplant, human decision-making, particularly for decisions that hinge on predictions. As a result, two additional features in addition to prediction quality have generated interest: (i) to ...

The proliferation of smartphones has provided a huge market for mobile apps and created a massive industry for developers/designers creating various mobile apps for use in our daily activities. However, with many mobile apps competition for users ...

Originating from the simple and tasteful minimalist aesthetics of the design community and the Buddhist-style attitude towards life, combined by explorers of animation creation, simple Chinese ink animation short films have rapidly caught the ...

In this paper, we study the first eigenvalue of a nonlinear elliptic system involving p-Laplacian as the differential operator. The principal eigenvalue of the system and the corresponding eigenfunction are investigated both ...

(I) Synchronic norms of theory choice, a traditional concern in scientific methodology, restrict the theories one can choose in light of given information. (II) Diachronic norms of theory change, as studied in belief revision, restrict how one ...

Traditionally, belief change is modelled as the construction of a belief set that satisfies a success condition. The success condition is usually that a specified sentence should be believed (revision) or not believed (contraction). Furthermore, ...

• The study investigates the role of simplicity and emotions in determining WOM intentions.

With the known poor user retention rates of mobile apps, mobile app developers and service providers can significantly benefit from positive word-of-mouth (WOM) as a cost-effective means to reach a critical mass. Many users abandon ...
