Abstract

Handwritten digit recognition is a process of recognizing and identifying numbers using artificial intelligence algorithms such as Convolutional Neural Network (CNN). The application of handwritten number recognition can be developed and used in identifying postal code numbers on letters, identifying nominal amounts on bank checks and others. However, before carrying out the application, model training is needed on the algorithm that will be used so that number recognition is accurate because the problem faced in recognizing handwritten numbers is that images or written data are diverse and difficult to identify. In this study, the CNN algorithm was used with the SquuezeNet architecture with the MNIST (Modified National Institute of Standards and Technology) dataset which is divided into 60,000 training data and 10,000 test data. The platform used to carry out the training and testing process is Google Colab. Training was carried out 12 times using hyperparameters such as Optimizer namely Adam, SGD, and RMSprop, Learning rate namely 0.1, 0.01, 0.001, 0.0001 and Batch Size 64. Based on the research results from 12 trained models, 1 model was obtained with the best results on the Optimizer namely Adam, Learning rate namely 0.0001 and Batch Size 64 resulting in an accuracy of 99.11%.

Abstract

This study evaluates the performance of the EfficientNet architecture for image classification on Fashion-MNIST (70,000 grayscale images, 10 classes). The training/testing split follows the standard 60,000/10,000 scheme, with an internal validation subset drawn from the training data. Preprocessing resizes images to match EfficientNet’s input requirements. The model is trained with the Adam optimizer (learning rate 0.001), batch size 32, for 20 epochs, with data augmentation and metric monitoring. Evaluation on the test set employs accuracy, precision, recall, F1-score, and the confusion matrix. The results show accuracy = 0.9429, precision = 0.9426, recall = 0.9429, and F1-score = 0.9425. Per-class analysis indicates that Trouser and Bag achieve the highest performance, while T-shirt/top and Shirt are most challenging due to visual similarity, as reflected in the confusion matrix. Compared with several baselines standard CNN, CNN-3-128, VGG16, XG-ViT (Vision Transformer), and DRQCNN EfficientNet attains the best overall score, although its advantage is relatively marginal; hence, practical significance depends on application goals.

Abstract

Identifying air pollution is a serious problem in various cities including Medan city. In this article, the use of IoT sensor-based mamdani fuzzy inference rules to identify air pollution in Medan city is discussed. Data collection is done through devices and systems built using IoT sensor devices. The IoT devices are installed in three different locations namely on Sei Deli, Tembung and KIM roads to monitor and collect air pollution data in real-time. Fuzzy inference rules are then used to process the sensor data and identify air pollution based on predefined threshold values. In addition to pollution factors, the determination of the time scale, namely early morning, morning, afternoon, evening and night is also a variable to identify air pollution based on time. The results show that the system built can identify air pollution based on data obtained through 3 devices with an average value of pollution in the "Medium" category.
