To date, nonparametric regression studies using a combined estimator model have recently begun to develop significantly. Yet previous research employing this approach is still restricted to models with a single response variable. Hence, this paper offers a novel method to estimate bi-response nonparametric regression using a model that combines Fourier series and truncated spline estimators. This research aims to estimate the regression curve of the proposed model using twostage estimation. The first stage is completed by the penalized weighted least square optimization followed by utilized the weighted least square optimization. We conduct numerical simulations with various sample sizes and correlations to assess the performance of the proposed model. Using generalized cross-validation as a criterion, the best model was obtained from the scenario model with big sample size and strong correlation. Furthermore, compared to uncombined estimators, the proposed model outperformed when applied to a real dataset of the human development index (HDI) education indicator in the East Java Province, Indonesia.

The preservation of traditional dances as an important part of world cultural heritage can be done by recording. While it is convenience to record the dances using video, this medium has limited capability in the reconstruction. On the other hand, recording using a motion capture device gives us the ability to replay them and add alterations in a creative process. In this paper, we propose a method to train traditional dance moves in a generative model using Long Short-Term Memory (LSTM). We use a traditional dance from East Java, Indonesia, that is called Remo Dance as the training data. The dance is recorded with a motion capture device and each basic move is trained into the model. In the sampling process, the trained model reiterates its memory into an unlimited length of dance animation. The generated dance animation has imperfection relative to the training data. This discrepancy gives the intended variations. We use visual assessments, dynamic time warping curves, and a subset of parameters from Laban motion analysis to evaluate the variations. These evaluations show how the variations behave and in what pattern they occur. In general, those variations give slight alterations to the motions that add human-like imperfection and give opportunities for animators and choreographers alike to explore new dances creations [ABSTRACT FROM AUTHOR]
