Abstract

This study aims to enhance the classification accuracy of batik motifs through a novel integration of Multi-Texton Co-Occurrence Descriptor (MTCD) and Binarized Statistical Image Features (BSIF). The primary objective is to develop a robust feature extraction method that effectively captures both textural and statistical properties of batik images, specifically utilizing the Batik Nitik 960 dataset. Our methodology employs a combination of MTCD and BSIF, followed by Principal Component Analysis (PCA) for dimensionality reduction, optimizing the model's ability to learn from diverse characteristics inherent in batik motifs to augment the diversity and robustness of the training data, we enhanced the Batik Nitik 960 dataset by applying vertical flipping, in addition to existing rotations. We explored three feature fusion approaches: Combination 1, where features are combined before normalization and PCA, achieving an accuracy of 99.948%; Combination 2, where normalization occurs prior to feature combination, also achieving an accuracy of 99.948%; and Combination 3, which applies PCA separately to each feature before combination, resulting in an accuracy of 99.896%. Experimental results demonstrate a remarkable accuracy in classifying these motifs, with the combined MTCD-BSIF features significantly surpassing the individual performances of MTCD at 95.729% and BSIF at 99.531%. This substantial improvement addresses the limitations identified in previous research, which reported an accuracy of only 0.71 on the same dataset. Furthermore, we explore the impact of various feature fusion techniques on classification performance, providing insights into the effectiveness of our proposed methods. Our findings suggest that the combined MTCD-BSIF approach can serve as a benchmark for future studies aiming to enhance classification accuracy in similar domains, thereby contributing to advancements in automated classification systems and their applications across various fields.

Abstract

Nitik batik is one of the most intricate and culturally significant motifs in Yogyakarta's batik tradition, characterized by its complex, geometric dot-based patterns. The unique challenges of automatically classifying nitik batik motifs stem from the high variability within the class and the limited availability of training data. This study investigates how different image data augmentation techniques can enhance the performance of a random forest classifier for nitik batik motifs. Techniques such as geometric transformations (flip, rotate, and scaling), intensity transformations (cut-out, grid mask, and random erasing), non-instance level augmentation (pairing samples), and unconditional image generation (deep convolutional generative adversarial network (DCGAN)) were used to expand the dataset and improve the model's ability to generalize. The results show that specific techniques, notably flip, cut-out, and DCGAN, significantly improved classification accuracy, with flip achieving the highest accuracy improvement of 20.20%, followed by cut-out at 19.27% and DCGAN at 16.25%. Moreover, DCGAN demonstrated the lowest standard deviation (0.78%), indicating high stability and robustness in classification performance across multiple validation folds. These findings suggest that augmentation techniques effectively improve classification accuracy and enhance the model's ability to generalize from limited and complex datasets.

Abstract

Pandemi mengharuskan pihak sekolah untuk menerapkan sistem pembelajaran online. Perubahan cara kerja pembelajaran yang semula diterapkan melalui sistem pembelajaran tatap muka kemudian dilakukan secara online (daring) menyebabkan siswa dan para orang tua perlu melakukan adaptasi untuk perubahan tersebut. Tujuan dari penelitian ini adalah untuk melakukan klasifikasi terhadap kemampuan adaptasi siswa dengan diberlakukannya pembelajaran online (daring) dengan menggunakan bantuan Algoritma Naive Bayes. Pemilihan algoritma Naïve Bayes dilakukan karena mudah dan cepat untuk diimplementasikan. Metode lain yang digunakan adalah metode  untuk melakukan feature selection. Data splitting yang dipilih pada penelitian ini adalah 70% untuk data training dan 30% untuk data testing. Evaluasi model yang dilakukan dengan jumlah Information Gain feature yang berbeda yakni 3, 6, 9, dan 13 kombinasi feature yang memiliki nilai gain terbaik. Sedangkan, jumlah information gain untuk mendapatkan feature terbaik yaitu saat menghasilkan 6 feature. Feature terbaiknya yaitu Class Duration, Financial Condition, Age, Institution Type, Location, dan Device. Penelitian ini juga membandingkan penggunaan library dan yang menggunakan perhitungan manual. Pemilihan feature selection dipilih 6 feature maka didapatkan hasil accuracy tertinggi jika dihitung dengan perhitungan manual menghasilkan accuracy sejumlah 66.02%, sedangkan jika dihitung dengan perhitungan library nilai accuracy yang dihasilkan adalah 66.29%. Penggunaan library terpantau memiliki perbedaan hasil dibandingkan dengan perhitungan manual karena adanya perbedaan step yang digunakan.
