Abstract

This study aims to determine and describe the level of mathematical connection ability of students in solving mathematical investigation questions in grade VII students at SMPN 2 Labuapi in the academic year 2020/2021. This type of research is descriptive qualitative research. The subjects in this study were 10 students of VII A class at SMPN 2 Labuapi. The data was collected in the form of test results of students' mathematical connection skills in solving mathematical investigation questions at triangles and quadrangle matter and the results of interviews. The test results were analyzed according to the indicators of students' mathematical connection ability, which is being able to connect the mathematical concepts that have been studied and those being studied and to connect the mathematical concepts to everyday life. Based on the results of data analysis, that the mathematical connection ability of students in solving mathematical investigation questions was still in the sufficient category. Overall there were 3 students (30%) in very poor category, 2 students (20%) in very good category, 2 students (20%) in good category, 2 students (20%) in good enough category, and 1 student (10%) in poor category.

Abstract

In this digital era, artificial intelligence has become very popular due to its very wide scope of application. Various models and methods in artificial intelligence are developed with their respective purposes. However, each model and method certainly requires a reliable optimizer in the training process. Many optimizers have been developed and are increasingly reliable lately. In this article, we classify the synopsis texts of several movies into nine different genre classes, leveraging Natural Language Processing (NLP) with Long Short Term Memory (LSTM) and Embedding to build models. Models are trained using several optimizers, including stochastic gradient descent (SGD), AdaGrad, AdaDelta, RMSProp, Adam, AdaMax, Nadam, and AdamW. Meanwhile, various metrics are used to evaluate the model, such as accuracy, recall, precision, and F1-score. The results show that the model structure with embedding, lstm, double dense layer, and dropout 0.5 returns satisfactory accuracy. Optimizers based on Adaptive moments provide better results when compared to classical methods, such as stochastic gradient descent. AdamW outperforms other optimizers as indicated by its accuracy on validation data of 89.48%. Slightly behind it are several other optimizers such as Adam, RMSProp, and Nadam. Moreover, the genres that have the highest metric values are the drama and thriller genres, based on the recall, precision and F1-score values. Meanwhile, the horror, adventure and romance genres have low recall, precision and F1-score values. Moreover, by applying Random Over Sampling (ROS) to balance the genre dataset, the model’s testing accuracy improved to 98.1%, enhancing performance across all genres, including underrepresented ones. Additional testing showed the model’s ability to generalize well to unseen data, confirming its robustness and adaptability.
