Twitter sebagai platform yang digandrungi masyarakat terbukti dengan data yang menunjukkan bahwa Indonesia peringkat lima di dunia dengan banyak pengguna mencapai 18.4 juta. Banyak pengguna mengutarakan pendapat di dalam Twitter. Skincare lokal kini sedang merajai industri kecantikan di Indonesia. Beberapa brand kecantikan yang menggunakan artis korea sebagai brand ambassador. Berdasarkan hal tersebut, maka dilakukan analisis sentimen menggunakan algoritma Support Vector Machine (SVM)  dan naïve bayes untuk mengetahui bagaimana sentimen para pengguna terhadap penggunaan artis korea sebagai brand ambassador produk kecantikan lokal. Data yang digunakan merupakan komentar masyarakat twitter sebanyak 317 data yang terdiri 266 komentar positif dan 21 komentar negatif. Hasil terbaik diperoleh pada SVM dengan nilai akurasi  83.60% dengan precision 83.86% dan recall 99.62%.

Predicting early Type 2 diabetes (T2D) is critical for improved care and better T2D outcomes. An accurate and efficient T2D prediction relies on unbiased relevant features. In this study, we searched for important features to predict T2D by integrating ML-based models for feature selection and classification from 520 individuals newly diagnosed with diabetes or who will develop it. We used standard machine learning classifications, such as logistic regression (LR), Gaussian naive Bayes (NB), decision tree (DT), random forest (RF), support vector machine (SVM) with linear basis function, and k-nearest neighbors (KNN). We set out to systematically explore the viability of main feature selection representing each different technique, such as a statistical filter method (F-score), an entropy-based filter method (mutual information), an ensemble-based filter method (random forest importance), and a stochastic optimization (simultaneous perturbation feature selection and ranking (SpFSR)). We used a stratified 10-fold cross-validation technique and assessed the performance of discrimination, calibration, and clinical utility. We attained the highest accuracy of 98% using RF with the full set of features (16 features), then used RF as a classifier wrapper to select the important features. We observed a combination of SpFSR and RF as the best model with a P-value above 0.05 (P-value = 0.26), statistically attaining the same accuracy as the full features. The study's findings support the efficiency and usefulness of the suggested method for choosing the most important features of diabetic data: polyuria, gender, polydipsia, age, itching, sudden weight loss, delayed healing, and alopecia.

Every company always has a recruitment selection process with the hope that the company can get competent employees. The selection process usually has several criteria that are usually predetermined by the company which are needed in the initial selection process for hiring employees. Thus it is necessary for an application system that can carry out the initial screening process for employee recruitment to assist the implementation of the selection process. The design of this application uses the FSA implementation with the NFA type as an abstract machine to determine the stages and transitions contained in these stages which are used to determine the results of the initial screening of employee recruitment. If they meet the specified criteria, they will pass at this stage. This is a role in making abstract machines for the initial screening process for employee recruitment using Nondeterministic Finite Automata (NFA) because each stage can lead to several stages at once.
