Non-Cash Food Assistance or Bantuan Pangan Non-Tunai (BPNT) is food assistance from the government given to the Beneficiary Family (KPM) every month through an electronic account mechanism that is used only to buy food at the Electronic Shop Mutual Assistance Joint Business Group Hope Family Program (e-Warong KUBE PKH ) or food traders working with Bank Himbara. In its distribution, BPNT still has problems that occur that are experienced by the village apparatus especially the apparatus of Desa Wanasari on making decisions, which ones are worthy of receiving (poor) and not worthy of receiving (not poor). So one way that helps in making decisions can be done through the concept of data mining. In this study, a comparison of 2 algorithms will be carried out namely Naive Bayes Classifier and Decision Tree C.45. The total sample used is as much as 200 head of household data which will then be divided into 2 parts into validation techniques is 90% training data and 10% test data of the total sample used then the proposed model is made in the RapidMiner application and then evaluated using the Confusion Matrix table to find out the highest level of accuracy from 2 of these methods. The results in this classification indicate that the level of accuracy in the Naive Bayes Classifier method is 98.89% and the accuracy level in the Decision Tree C.45 method is 95.00%. Then the conclusion that in this study the algorithm with the highest level of accuracy is the Naive Bayes Classifier algorithm method with a difference in the accuracy rate of 3.89%.

Healthcare industry collects huge amount of unclassified data every day.  For an effective diagnosis and decision making, we need to discover hidden data patterns. An instance of such dataset is associated with a group of metabolic diseases that vary greatly in their range of attributes. The objective of this paper is to classify the diabetic dataset using classification techniques like Naive Bayes, ID3 and k means classification. The secondary objective is to study the performance of various classification algorithms used in this work. We propose to implement the classification algorithm using R package. This work used the dataset that is imported from the UCI Machine Learning Repository, Diabetes 130-US hospitals for years 1999-2008 Data Set. Motivation/Background: Naïve Bayes is a probabilistic classifier based on Bayes theorem. It provides useful perception for understanding many algorithms. In this paper when Bayesian algorithm applied on diabetes dataset, it shows high accuracy. Is assumes variables are independent of each other. In this paper, we construct a decision tree from diabetes dataset in which it selects attributes at each other node of the tree like graph and model, each branch represents an outcome of the test, and each node hold a class attribute. This technique separates observation into branches to construct tree. In this technique tree is split in a recursive way called recursive partitioning. Decision tree is widely used in various areas because it is good enough for dataset distribution. For example, by using ID3 (Decision tree) algorithm we get a result like they are belong to diabetes or not. Method: We will use Naïve Bayes for probabilistic classification and ID3 for decision tree.  Results: The dataset is related to Diabetes dataset. There are 18 columns like – Races, Gender, Take_metformin, Take_repaglinide, Insulin, Body_mass_index, Self_reported_health etc. and 623 rows. Naive Bayes Classifier algorithm will be used for getting the probability of having diabetes or not. Here Diabetes is the class for Diabetes data set. There are two conditions “Yes” and “No” and have some personal information about the patient like - Races, Gender, Take_metformin, Take_repaglinide, Insulin, Body_mass_index, Self_reported_health etc. We will see the probability that for “Yes” what unit of probability and for “No” what unit of probability which is given bellow. For Example: Gender – Female have 0.4964 for “No” and 0.5581 for “Yes” and for Male 0.5035 is for “No” and 0.4418 for “Yes”. Conclusions: In this paper two algorithms had been implemented Naive Bayes Classifier algorithm and ID3 algorithm. From Naive Bayes Classifier algorithm, the probability of having diabetes has been predicted and from ID3 algorithm a decision tree has been generated.

Pandemi COVID-19 memberikan dampak diberbagai aspek. Salah satu yang terkena dampak adalah transportasi umum. Transportasi umum mengalami penurunan jumlah penumpang yang signifikan, seperti Transjakarta sebesar 34,52%, MRT  94,11%  dan KRL 78,69%. Penurunan ini disebabkan oleh kebijakan yang dikeluarkan untuk mendukung upaya pemerintah dalam pencegahan penyebaran virus Covid-19, seperti memangkas jam operasional, mengurangi perjalanan yang akan dijadwalkan sampai pembatasan penumpang setiap gerbong. Kebijakan ini memicu opini penumpang mengenai pelayanan yang diberikan. Opini tersebut dapat dituangkan melalui berbagai media salah satunya Twitter. Opini penumpang yang tertuang didalam twitter mengenai pelayanan transportasi umum dapat bersifat positif atau pun negatif. Opini penumpang dapat digunakan sebagai data dalam melakukan analisis sentimen, data ini dapat diperoleh dengan menggunakan teknik crawling. Analisis sentimen dilakukan untuk mengetahui kecenderungan opini penumpang mengenai pelayanan transportasi umum selama pandemi Covid-19. Data yang didapatkan sebanyak 650 data yang diberikan label positif dan negatif. Data dibagi menjadi data latih sebanyak 60 % atau 390 data, dan data uji 40% atau 260 data. Data ini dapat digunakan untuk proses pembuatan model mechine learning menggunakan Metode algoritma Naïve Bayes Classifier. Hasil pembentukan model mechine learning ini memiliki tingkat akurasi sebesar 83,8%  yang dihasilkan dari pengujian data uji dengan menggunakan confusion matrix.

Twitter Data

Pilpres saat ini cukup menyita perhatian, karena berbagai rumor yang beredar. Masyarakat juga menjadi sasaran elit politik, dimana suara mereka merupakan penentu keberlangsungan arah politik untuk lima tahun kedepan. Opini-opini positif, netral maupun negatif dapat menimbulkan ancaman munculnya berita bohong (hoax). Salah satu sarana yang digunakan masyarakat dalam mengekspresikan pilihan politiknya adalah melalui media sosial salah satunya twitter. Data seperti opini publik dapat diolah menjadi sebuah informasi yang bermanfaat, salah satunya melalui analisis sentimen. Pada penelitian ini, akan dilakukan analisis sentimen pada Twitter tentang pemilihan presiden 2019. Tahapan analisis sentimen pada penelitian ini terdiri dari akuisisi data, pre-processing, klasifikasi data, evaluasi data dan visualisasi data. Preprocessing dilakukan dengan case folding, normalisasi data, filtering, ubah kata baku, stopword dan stemming. Penelitian ini melakukan 2 metode yaitu dengan metode Lexicon Based dan Naïve Bayes Classifier. Hasil akhir dari analisis kemudian dihitung nilai akurasi menggunakan confusion matrix dan di visualisasikan menggunakan web server. Penentuan sentimen prediksi dilakukan menggunakan metode Lexicon Based dan Labelisasi dengan perhitungan secara manual. Data latih dan data uji akan digunakan dalam proses pelatihan dan pengujian menggunakan Naive Bayes Classifier. Hasil klasifikasi yang dilakukan oleh metode Naive Bayes Classifier disebut sentimen aktual. Perhitungan tingkat keakurasian antara sentimen prediksi terhadap sentimen aktual menggunakan pengujian confusion matrix. Hasil yang didapatkan adalah tingkat akurasi antara sentimen prediksi dan sentimen aktual dengan Lexicon Based sebesar 64,49% pada data uji dan pada data latih sebanyak 94,2% serta dengan menggunakan Labelisasi dan Naive Bayes Classifier sebesar 86,53% pada data uji dan data latih sebesar 94,08%. Hasil penelitian ini diharapkan dapat membantu melakukan riset atas opini masyarakat pada Twitter mengenai Pilpres 2019 yang mengandung sentimen positif, negatif atau netral.

Probabilistic Classifier

Document clustering partitions sets of unlabeled documents so that documents in clusters share common concepts. A Naive Bayes Classifier (BC) is a simple probabilistic classifier based on applying Bayes’ theorem with strong (naive) independence assumptions. BC requires a small amount of training data to estimate parameters required for classification. Since training data must be labeled, we propose an Iterative Bayes Clustering (IBC) algorithm. To improve IBC performance, we propose combining IBC with Comparative Advantage-based (CA) initialization method. Experimental results show that our proposal improves performance significantly over classical clustering methods.
