Kredit tanpa agunan (KTA) adalah salah satu produk kredit yang diberikan bank kepada nasabah kredit dalam bentuk fasilitas pinjaman tanpa ada suatu jaminan. Karena tidak ada jaminan atas pinjaman tersebut maka bank harus berhati-hati memeriksa calon nasabah kredit agar tidak terjadi resiko kerugian di kemudian hari. Pengajuan aplikasi KTA oleh nasabah kepada pihak bank akan dilakukan penilaian berdasarkan teknik klasifikasi. Teknik klasifikasi pada KTA ini menggunakan metode pendekatan statistik yaitu regresi logistik dan ANN. Regresi logistik merupakan salah satu metode parametrik yang tidak disyaratkan asumsi-asumsi sebagaimana yang harus dipenuhi apabila melakukan analisis data dengan menggunakan regresi linear. Metode ANN adalah pemrosesan informasi yang terinspirasi oleh sistem syaraf biologi (Haykin,1999). Metode regresi logistik memiliki kemampuan untuk  menentukan peubah penjelas yang berpengaruh  terhadap peubah respon hasil keputusan. Regresi logistik dengan peubah penjelas berpengaruh yaitu jenis kelamin, jumlah cicilan 12 bulan, jumlah cicilan 24 bulan, dan standar gaji. Jadi pihak bank dapat menjadikan peubah penjelas tersebut sebagai pertimbangan untuk menentukan hasil keputusan nasabah KTA. Berdasarkan nilai ketepatan klasifikasi confusion matrix, nilai akurasi, dan AUC pada data training dan data testing metode yang terbaik pada data nasabah KTA yaitu ANN Backpropagation diikuti oleh regresi logistik.Kata Kunci :    Kredit Tanpa Agunan, Artificial Neural Network (ANN) Backpropagation, Regresi Logistik.

Abstract Stuck pipe is one of the leading causes of non-productive time (NPT) while drilling. Machine learning (ML) techniques can be used to predict and avoid stuck pipe issues. In this paper, a model based on ML to predict and prevent stuck pipe related to differential sticking (DS) is presented. The stuck pipe indicator is established by detecting and predicting abnormalities in the drag signatures during tripping and drilling activities. The solution focuses on detecting differential sticking risk via assessing hookload signatures, based on previous experience from historical wells. Therefore, selecting the proper training set has proven to be a crucial stage of model development, especially considering the challenges in data quality. The model is trained with historical wells with and without differential sticking issues. The solution is based on the Artificial Neural Network (ANN) approach. The model is designed to provide users, i.e., driller or monitoring specialist, a warning whenever a risk is identified. Since multi-step forecasting is used, the warning is given with enough time for the driller or monitoring specialist to evaluate which preventative action or intervention is necessary. The warnings are provided typically between 30 minutes and 4 hours ahead. The model validation includes the performance metrics and a confusion matrix. Practical cases with real-time wells are also provided. The ML model was proven robust and practical with our data sets, for both historical and live wells. The huge amount of data produced while drilling holds valuable information and when smartly fed into an Artificial Intelligence (AI) model, it can prevent NPT such as stuck pipe events as demonstrated in this paper.

A self-balancing type of robot works on the principle of maintaining the balance of the load's position to remains in the center. As a consequence of this principle, the driver can go forward reverse the vehicle by leaning in a particular direction. One of the factors affecting the control model is the weight of the driver. A control system that has been designed will not be able to balance the system if the driver using the vehicle exceeds or less than the predetermined weight value. The main objective of the study is to develop a semi-adaptive control system by implementing an Artificial Neural Network (ANN) algorithm that can estimate the driver's weight and use this information to reset the gain used in the control system. The experimental results show that the Artificial Neural Network can be used to estimate the weight of the driver's body by using 50-ms-duration of tilt sensor data to categorize into three defined classes that have been set. The ANN algorithm provides a high accuracy given by the results of the confusion matrix and the precision calculations, which show 99%.

In this paper to make use of complementary potential in the mapping of LULC spatial data is acquired from LandSat 8 OLI sensor images are taken in 2019.  They have been rectified, enhanced and then classified according to Random forest (RF) and artificial neural network (ANN) methods. Optical remote sensing images have been used to get information on the status of LULC classification, and extraction details. The classification of both satellite image types is used to extract features and to analyse LULC of the study area. The results of the classification showed that the artificial neural network method outperforms the random forest method. The required image processing has been made for Optical Remote Sensing Data to be used in LULC mapping, include the geometric correction, Image Enhancements, The overall accuracy when using the ANN methods 0.91 and the kappa accuracy was found 0.89 for the training data set. While the overall accuracy and the kappa accuracy of the test dataset were found 0.89 and 0.87 respectively.

Computer vision and image processing are extremely necessary for medical pictures analysis. During this paper, a method of Bio-inspired Artificial Intelligent (AI) optimization supported by an artificial neural network (ANN) has been widely used to detect pictures of skin carcinoma. A Moth Flame Optimization (MFO) is utilized to educate the artificial neural network (ANN). A different feature is an extract to train the classifier. The comparison has been formed with the projected sample and two Artificial Intelligent optimizations, primarily based on classifier especially with, ANN-ACO (ANN training with Ant Colony Optimization (ACO)) and ANN-PSO (training ANN with Particle Swarm Optimization (PSO)). The results were assessed using a variety of overall performance measurements to measure indicators such as Average Rate of Detection (ARD), Average Mean Square error (AMSTR) obtained from training, Average Mean Square error (AMSTE) obtained for testing the trained network, the Average Effective Processing Time (AEPT) in seconds, and the Average Effective Iteration Number (AEIN). Experimental results clearly show the superiority of the proposed (ANN-MFO) model with different features.
