This review aims to draw attention to two issues of concern when we set out to make machine learning work in the chemical and materials domain, i.e., statistical loss function metrics for the validation and benchmarking of data-derived models, and the uncertainty quantification of predictions made by them. They are often overlooked or underappreciated topics as chemists typically only have limited training in statistics. Aside from helping to assess the quality, reliability, and applicability of a given model, these metrics are also key to comparing the performance of different models and thus for developing guidelines and best practices for the successful application of machine learning in chemistry.

IOP Conference Series: Materials Science and engineering 2021年第1期1087卷

作者： S Rahman M Ramli F Arnia R Muharar A Sembiring Doctoral Program School of Engineering Universitas Syiah Kuala Banda Aceh Department of Mathematics Universitas Syiah Kuala Banda Aceh Department of Electrical and Computer Engineering Universitas Syiah Kuala Banda Aceh Department of Informatics Technology Universitas Harapan Medan

Information on the availability of parking spaces is one of the main needs in urban areas. This information can minimize the impact of vehicle growth, including exhaust gas emissions, traffic jams, and fuel use. In general, the detection of parking space availability can be done in two ways, namely the sensor system and computer vision. Computer vision monitoring of parking spaces is more promising for use in the future. A single-camera can monitor multiple parking spaces by making use of computer vision. CNN is a technique for parking space classification. CNN's pre-trained dedicated to parking space classification is mAlexnet. mAlexnet can classify parking spaces well, but not perfect. in this paper, we try to observe and improve the performance of mAlexnet. We tried training options and activation function tuning. From the results of testing the combination of SGDM training option and the LeakyReLu activation function, the performance of mAlexnet improves.

Feeding on shrimp culture is important to the shrimp growth process so that the expected yields are achieved. Feeding must be balanced and timely, there are no advantages or disadvantages in feeding because all the feed provided is not necessarily completely consumed by shrimp, therefore it is necessary to have technology that can control shrimp feeding. Automatic shrimp feed technology can be a solution to the problem of feeding to support the productivity of shrimp culture. Automatic shrimp feeder is built using an arduino microcontroller module, RTC module (Real Time Clock), and feed throwing system. The shrimp feeding method with the working principle of shrimp feeder is shrimp feed thrown horizontally due to centrifugal force. With the influence of the centrifugal force from the propeller spreader, the feed will be thrown throughout the surface of the pond. Feeding is controlled using Arduino by setting the time. Shrimp feeding is done every 4 hours and the appliance is on for 7 minutes to spread 10 kg of feed for the number of shrimps 1,500 and the width of kolan 400 m2 with a minimum throwing distance of feed 1 meter and a maximum of 7 meters.

作者： Alfredo Gormantara Pranowo 1Informatics Engineering Graduate Program Universitas Atma Jaya Yogyakarta Yogyakarta 55281 Indonesia

One of the reaction-diffusion type differential equations is the formation of the Turing pattern. This paper describes the numerical simulation of the reaction-diffusion equations of FitzHugh-Nahumo model. This model is one of Turing systems, which can be used as a mathematical model of pattern formation in animal skin. The model is solved numerically using a finite difference method while the time evolution is discretized by using explicit Euler scheme. For reduction, the elapsed time, the parallel algorithm based on Graphical Processing Unit (GPU) with CUDA was used. This study compares the elapsed time of the CPU and GPU, numerical experiments were carried out using various mesh sizes. The results show that parallel implementation of GPU achieves acceleration up to 12 times faster than the serial CPU implementation. The greater the computing resources needed will make GPU use more optimal.
