Abstract

Abstract - invasive species are threatening indigenous species habitat in many countries around the world. Nowadays, the monitoring method relies on scientists. Scientists are skilled to see the determined areas and record the living species. Applying high skill labors requires high cost, inefficient time and limited scope as the large area cannot be reached by the man. In this research, engine based learning approach was presented to identify the image of invasive hydrangea (indigenous species from Asia) with data collection around 800 images taken form the Brazil national forest and Hydrangea appears in some images. Gradient Descent optimization method is frequently used for artificial neural network. This method roles to discover standard grade for the best output. The Gradient Descent method role play is minimizing the cost function grade by changing the parameter grade step by step. Three optimization methods have been implemented namely Stochastic Gradient Descent (SGD), ADADELTA, and Adam in the artificial neural network (Ann) for classifying aritmia data [32]. This research used the most suitable error grade limitation from each optimization method as the indicators at the end of the training. The result of this research showed that artificial nerve tissue using Adam optimization gets the highest accuration compared with SDG and ADADELTA optimization methods. Deep Learning Technique applied extensively in image introduction is Adam optimization. The training model has reached accuration to 83, 5 % and showed properness of approach conducted. Keyword: SGD, Adadelta, Adam, Optimizer FunctionAbstrak— Spesies invasif mengancam habitat spesies asli di banyak negara di dunia. Saat ini dalam metode pemantauan mereka tergantung pada pengetahuan ahli. Ilmuwan terlatih mengunjungi area yang ditentukan dan mencatat spesies yang menghuninya. Menggunakan tenaga kerja berkualifikasi tinggi seperti itu membutuhkan biaya yang mahal, tidak efisien waktu dan jangkauan yang terbatas karena manusia tidak dapat mencakup area yang luas. Dalam makalah ini, pendekatan berbasis pembelajaran mesin disajikan untuk mengidentifikasi gambar hydrangea invasif (spesies invasif asli Asia) dengan kumpulan data yang berisi sekitar 800 gambar yang diambil di hutan nasional Brasil dan di beberapa gambar terdapat Hydrangea.  Metode optimasi Gradient Descent sering digunakan untuk pelatihan Jaringan Syaraf Tiruan (JST). Metode ini berperan dalam menemukan nilai bobot yang memberikan nilai keluaran terbaik. Prinsip kerja metode Gradient Descent adalah memperkecil nilai fungsi biaya dengan mengubah nilai parameter selangkah demi selangkah. Telah diimplementasikan tiga buah metode optimasi yaitu Stochastic Gradient Descent (SGD), ADADELTA, dan Adam pada sistem Jaringan Saraf Tiruan untuk klasifikasi data aritmia [32]. Penelitian ini menggunakan batas nilai kesalahan yang paling sesuai dari masing-masing metode optimasi  sebagai kriteria pemberhentian pelatihan. Hasil penelitian menunjukkan Jaringan Saraf Tiruan dengan optimasi Adam menghasilkan akurasi tertinggi dibandingkan dengan dengan metode optimasi SGD dan ADADELTA.Teknik Deep Learning  yang diterapkan secara ekstensif pada pengenalan gambar yang digunakan memanfaatkan metode optimizer Adam  . Model yang kita latih menggunakan fungsi optimisasi Adam mencapai akurasi 83,5% pada tes yang lakukan, menunjukkan kelayakan pada  pendekatan yang dilakukan .Kata Kunci— SGD, Adadelta, Adam, Fungsi Optimasi

Abstract

A civil servant or civil servant (English: civil servant, Dutch: ambtenaar) is a person employed by a government agency to provide public services. As a profession, civil servants are positions that are pursued through career paths and not based on general elections involving the people's vote. Quoted from the Regulation of the Head of BKN No. 35 of 2011 concerning Guidelines for the Preparation of PNS Careers, the career pattern of civil servants is arranged based on the principles of certainty, professionalism, and transparency. One of the requirements to achieve the desired career is through the promotion process. The promotion or class of a civil servant cannot be separated from the recommendation of the leadership. A leader in providing recommendations must look at several important points that must be possessed by employees who will be given recommendations such as Attendance, Integrity, Cooperation and Insight or Knowledge. In the process, there are still problems in terms of technical and effectiveness because manual assessments sometimes still assess subjectively. Therefore, a study was carried out for the classification of the determination of the status of giving recommendations using the Naïve Bayes method. Naive Bayes is one method of probabilistic reasoning. The Naive Bayes algorithm aims to classify data in certain classes, then the pattern can be used to estimate the employee who will be given a recommendation, so that the leader can make a decision to give recommendation or not to the employee

Abstract

Many measures have been taken to protect endangered species by using "camera trap" technology which is widespread in the field of technology-based nature protection field research. In this study, a machine learning-based approach is presented to identify endangered wildlife images with a data set containing 5000 images taken from Kaggle and some other sources. The Gradient Descent optimization method is often used for Artificial Neural Network (ANN) training. This method plays a role in finding the weight values that give the best output value. Three optimization methods have been implemented, namely Stochastic Gradient Descent (SGD), ADADELTA, and Adam on the Artificial Neural Network system for animal data classification. In some of the studies reviewed there are differences in the results of SGD and ADAM, which on the one hand SGD is superior, and on the one hand ADAM is superior with the appropriate learning rate. The results of this study show that the CNN method with the Adam optimization function produces the highest accuracy compared to the SGD and RMSprop optimization methods. The model trained using Adam's optimization function achieved an accuracy of 89.81% on the test, showing the feasibility of the approach.
