Abstract Classification tasks are an integral part of science, industry, business, and health care systems; being such a pervasive technique, its smallest improvement is valuable. Artificial Neural Network (ANN) is one of the strongest techniques used in many disciplines for classification. The ANN technique suffers from drawbacks such as intransparency in spite of its high prediction power. In this paper, motivated by learning styles in human brains, ANN's shortcomings are assuaged and its prediction power is improved. Self-Organizing Map (SOM), an ANN variation which has strong unsupervised power, and Feedforward ANN, traditionally used for classification tasks, are hybridized to solidify their benefits and help remove their limitations. The proposed method, which we name Self-Organizing Error-Driven (SOED) Artificial Neural Network, shows significant improvements in comparison with usual ANNs. We show SOED is a more accurate, more reliable, and more transparent technique through experimentation with five different datasets. Highlights A synthesis of MLP and SOM is presented for tackling classification challenges. The superiority of SOED over MLP in addressing 5 classification tasks is presented. SOED is compared with other states of the art techniques such as DT, KNN, and SVM. It is shown that SOED is a more accurate and reliable in comparison with MLP. It is shown SOED is more accurate, reliable and transparent in comparison with MLP.

Background: Human face is a biometric feature. Artificial Intelligence (AI) called Artificial Neural Network (ANN) can be used in recognising such a biometric feature. In ANN, the learning process is divided into two: supervised and unsupervised learning. In supervised learning, a common method used is Backpropagation, while in the unsupervised learning, a common one is Kohonen Self Organizing Map (KSOM). However, the application of Backpropagation and KSOM need to be adjusted to improve the performance.Objective: In this study, Backpropagation and KSOM algorithms are rewritten to suit face image recognition, applied and compared to determine the effectiveness of each algorithm in solving face image recognition.Methods: In this study, the methods used and compared in the case of face image recognition are Backpropagation dan Kohonen Self Organizing Map (KSOM) Artificial Neural Network (ANN).Results: The smallest False Acceptance Rate (FAR) value of Backpropagation is 28%, and KSOM is 36%, out of 50 unregistered face images tested. While the smallest False Rejection Rate (FRR) value of Backpropagation is 22%, and KSOM is 30%, out of 50 registered face images. The fastest time for the training process using the backpropagation method is 7.14 seconds, and the fastest time for recognition is 0.71 seconds. While the fastest time for the training process using the KSOM method is 5.35 seconds, and the fastest time for recognition is 0.50 seconds.Conclusion: Backpropagation method is better in recognising face images than KSOM method, but the training process and the recognition process by KSOM method are faster than Backpropagation method due to the hidden layers. Keywords: Artificial Neural Network (ANN), Backpropagation, Kohonen Self Organizing Map (KSOM), Supervised learning, Unsupervised learning

Artificial Neural Network (ANN) sebagai sebuah metode analitik dalam data science memiliki kemampuan pada bidang  klasifikasi, asosiasi, self organizing dan optimasi. Dengan kemampuan tersebut ANN dapat menciptakan suatu pola pengetahuan melalui pengaturan diri atau kemampuan belajar (self-organizing) bahkan mampu memetakan kumpulan data berdasarkan ciri-ciri kesamaan yang ada pada data tersebut dengan mekanisme Self Organizing Mapping (SOM). Kemampuan SOM dalam melakukan pemetaan terhitung cukup valid dan rendah bias, karena mengkalkulasi secara mandiri dan cepat berdasarkan kesamaan ciri atau karakter data yang diinput. Pada penelitian ini SOM diterapkan untuk pemetaan industi pada industri mesin pertanian dan kehutanan. Mengingat selama ini kekuatan industri mesin pertanian dan kehutanan dengan kode Kelompok Lapangan Usaha Industri (KLUI) 2921 belum dipetakan dengan sempurna. Data industri yang menjadi input pada program terlebih dahulu ditransformasi dengan aktivasi sigmoid biner dan  selanjutnya dimasukkan ke dalam program jaringan competitive kohonen. Berdasarkan perhitungan metode SOM dihasilkan klasifikasi industri dengan jenis menengah dan besar dengan capaian epoch 1000. Kata kunci: Data Science; Artificial Neural Network (ANN); Self Organizing Mapping (SOM); Klasifikasi Industri.
