Graph convolutional neural networks exploit convolution operators, based on some neighborhood aggregating scheme, to compute representations of graphs. The most common operators only local topological information. To consider wider receptive fields, the mainstream approach is non-linearly stack multiple graph (GC) layers. In this way, however, interactions among GC parameters at different level...

Semi-supervised learning (SSL) provides a way to improve the performance of prediction models (e.g., classifier) via usage unlabeled samples. An effective and widely used method is construct graph that describes relationship between labeled Practical experience indicates quality significantly affects model performance. In this paper, we present visual analysis interactively constructs high-qual...

The decarbonization of the transport system requires a better understanding human mobility behavior to optimally plan and evaluate sustainable options (such as Mobility Service). Current analysis frameworks often rely on specific datasets or data-specific assumptions hence are difficult generalize other studies. In this work, we present workflow identify groups users with similar that appear ac...

Given a graph G, a visual cryptography scheme based on the graph G is a method to distribute a secret image among the vertices of G, the participants, so that a subset of participants can recover the secret image if they contain an edge of G, by stacking their shares, otherwise they can obtain no information regarding the secret image. In this paper we apply maximal independent sets of the grap...

In this paper, face detection problem is considered using the concepts of compressive sensing technique. This technique includes dictionary learning procedure and sparse coding method to represent the structural content of input images. In the proposed method, dictionaries are learned in such a way that the trained models have the least degree of coherence to each other. The novelty of the prop...

هدف از پژوهشی که گزارش آن در رساله موجود آمده است بسط و بررسی محاسبه و ارزیابی نظریه ای است که بر اساس آن میتوان با اندازه گیری مقادیر تابع coherence امواج تداخلی حاصل از پوشش تشعشعی incoherent زمین در فواصل بسیار دور قدرت و پراکندگی آنها را محاسبه نمود. پس از آنکه رابطه ریاضی که توزیع قدرت تشعشعی پوشش uhf زمین را به مقادیر اندازه گرفته شده تابع coherence مربوط میسازد بدست آمد ثابت شده است که م...
