Pengaruh Pemberian Momentum Pada Artificial Neural Network Backpropagation

Salah satu algoritma Artificial Neural Network (ANN) yang biasa digunakan adalah algoritmabackpropagation dengan pola model gradient descent pada proses pembelajarannya. Akan tetapi,gradient descent memiliki kelemahan yaitu tidak mudah digunakan dan terkadang lambat dalampengkonvergenan solusinya. Untuk mengatasi kelemahan tersebut dilakukan suatu modifikasi yaitudengan memberikan momentum pada Perubahan bobotnya. Pada proses prediksi surface roughnesspada CNC Milling menggunakan ANN Backpropagation dengan momentum pada Perubahan bobotini, nilai rata-rata persentase error yang dihasilkan pada masing-masing nilai momentum yangdiberikan adalah tidak banyak mengalami Perubahan. Namun jika nilai momentum yang diberikanmendekati nilai maksimal momentum yaitu mendekati nilai satu maka akan menyebabkanterjadinya overshoot. Pemberian momentum pada Perubahan bobot menyebabkan Perubahan yangcukup besar yaitu pada waktu prosesnya, semakin besar nilai momentum yang diberikan makasemakin cepat pula waktu proses yang dibutuhkan. Hal ini berarti jika ingin waktu prosesprediksinya menjadi cepat maka gunakan nilai momentum yang besar, namun sebaiknya kurangdari 0.9

Research Promotion in Nursing, Physiotherapy, Occupational Therapy and Medical Engineering - Appeal and Recommendation to the Colleague -

[Summary] Despite of the severe situations of insufficient money, labor, time, and communication, we want to promote the research activity in our university to the level of major institutions. The first step we propose is to acquire the external research grants from public resources. The specific proposal is described in grant application to increase the probability of successful adoption of the grant from the Ministry of Education and Science of Japan

Id2-, RORγt-, and LTβR-independent initiation of lymphoid organogenesis in ocular immunity

The eye is protected by the ocular immunosurveillance system. We show that tear duct–associated lymphoid tissue (TALT) is located in the mouse lacrimal sac and shares immunological characteristics with mucosa-associated lymphoid tissues (MALTs), including the presence of M cells and immunocompetent cells for antigen uptake and subsequent generation of mucosal immune responses against ocularly encountered antigens and bacteria such as Pseudomonas aeruginosa. Initiation of TALT genesis began postnatally; it occurred even in germ-free conditions and was independent of signaling through organogenesis regulators, including inhibitor of DNA binding/differentiation 2, retinoic acid–related orphan receptor γt, lymphotoxin (LT) α1β2–LTβR, and lymphoid chemokines (CCL19, CCL21, and CXCL13). Thus, TALT shares immunological features with MALT but has a distinct tissue genesis mechanism and plays a key role in ocular immunity

The Physics of the B Factories

This work is on the Physics of the B Factories. Part A of this book contains a brief description of the SLAC and KEK B Factories as well as their detectors, BaBar and Belle, and data taking related issues. Part B discusses tools and methods used by the experiments in order to obtain results. The results themselves can be found in Part C
