Exploration of CNN Parameters to Measure Performance of LeNet-5 Architecture in Toraja Carving Classification

Toraja is a part of Indonesia located on the island of Sulawesi. One form of Toraja culture is carving art made from wood, bamboo or stone. There are around 70 types of Toraja carving motifs. With so many motifs and some motifs being almost similar to each other, it can make it difficult for the public and tourists to know the name of the motif. This research focuses on classifying Toraja carving images using Convolutional Neural Network (CNN) and measuring the performance of the LeN et-5 architecture. The number of Toraja carving motifs used in this research is 7 and the data is 700, where each motif is represented by 100 data. In testing, 3 explorations were carried out, namely dividing training and validation data, Batch Size values, and Target Size values. Based on test results, the 70:30 data division provides the highest level of accuracy compared to other data divisions. Increasing the Batch Size value has a negative impact on the level of accuracy. On the other hand, increasing the Target Size value has a positive impact on the accuracy value. The best Batch Size and Target Size values in this study were 32 and 256x256 with respective accuracies of 50.67% and 69.33%.
