Smart cities which are becoming overcrowded today are making human beings life miserable and prone to more challenges on daily basis. Overcrowded is leading to vast generation of wastes contributing to air pollution and in turn is affecting health causing various diseases. Even though various measures are taken to recycle wastes, the rate at which it is being produced is becoming higher and higher. This paper deals with prediction of waste generation using Naïve Bayes machine learning algorithm(Classifier) based on the statistics of previous waste datasets. The datasets used for the future prediction are obtained from reliable sources. The implementation of the algorithm is done in Pyspark using Anaconda Jupyter. The performance of the classifier on the datasets is analyzed with confusion matrix and accuracy metric is used to rate the efficiency of the classifier. The accuracy obtained indicates that algorithm can be effectively used for real time prediction and it gives more accurate results for huge input datasets based on independence assumption.

Now a day’s many advanced techniques are proposed in diagnosing the tumor in brain like magnetic resonance imaging, computer tomography scan, angiogram, spinal tap and biospy. Based on diagnosis it is easy to predict treatment. All of the types of brain tumor are officially reclassified by the World Health Organization. Brain tumors are of 120 types, almost each tumor is having same symptoms and it is difficult to predict treatment. For this regard we are proposing more accurate and efficient algorithm in predicting the type of brain tumor is Naïve Bayes’ classification and decision tree algorithm. The main focus is on solving tumor classification problem using these algorithms. Here the main goal is to show that the prediction through the decision tree algorithm is simple and easy than the Naïve Bayes’ algorithm.

Abstract:  Covid-19 has been set as a Pandemic by the World Health Organization (WHO). The very large impact and the infection that is fast enough are the reasons for making Covid-19 as a pandemic and efforts to overcome. One anticipation that can be done is to do lockdown. Making the decision to carry out a lockdown is intended to reduce the spread that occurs. Lockdown is certainly not a 100% good solution for all of individual. There are individual who agree that the lockdown will be implemented, also there are those who think that the lockdown is better not to be carried out considering the negative impacts that can occur. Therefore in this study will be presented the predictive modeling for sentiment analysis related to "lockdown" specially on social media Twitter. The method used to labeled was using Vader then the tweets are extracted using TF-IDF, and modeling is made for the prediction of sentiment using Naïve Bayes and Support Vector Machine. The results obtained from the two algorithms are more than 80%. Keywords: Covid-19, lockdown, TF-IDF, Naïve Bayes, Support Vector Machine Abstrak: Covid-19 telah ditetapkan sebagia Pandemi oleh World Health Organization (WHO). Dampak yang sangat besar dan penyebaran yang cukup cepat menjadi alsan untuk menjadikan Covid-19 sebagai Pandemi dan perlu dilakukan upaya penanggulangan. Salah satu upaya yang bisa dilakukan adalah dengan melakukan lockdown. Pengambilan keputusan untuk melakukan lockdown diperuntukan guna mengurangi penyebaran yang terjadi. Lockdown tentunya bukanlah solusi yang 100% baik bagi segala pihak. Terdapat pihak - pihak yang menyetujui akan dilaksanakannya lockdown, ada pula yang beranggapan bahwa lockdown lebih baik tidak dilaksanakan dengan pertimbangan dampak negatif yang bisa terjadi. Oleh karena itu, pada penelitian ini akan disampaikan mengenai pembuatan pemodelan prediksi terkait analisa sentimen terkait “Lockdown” yang dikhususkan pada media sosial Twitter. Metode yang digunakan adalah dengan melakukan labeling menggunakan Vader dan selanjutnya tweet tersebut dilakukan ekstraksi menggunakan TF-IDF, dan dibuatkan pemodelan untuk prediksi sentimen menggunakan Naïve Bayes dan Support Vector Machine. Hasil evaluasi yang didapat dari kedua algoritma tersebut ialah mencapai lebih dari 80%. Kata kunci: Covid-19, lockdown, TF-IDF, Naïve Bayes, Support Vector Machine Abstract:  Covid-19 has been set as a Pandemic by the World Health Organization (WHO).

Educational scholarships are one of the efforts to sustain students in getting a better education. Not a few students drop out in the middle of the road or cannot continue their education at the same level or higher level. Selection according to the criteria for scholarship recipients is important so that scholarships are on target. Similar to Depok Primary Middle School, educational scholarships are provided by schools based on 9 criteria for scholarship recipients, namely parent status, parent work, rented house, home appliances, vehicles, parents 'savings, parents' jewelry, cellphones and pocket money. With the number of prospective scholarship recipients there is an algorithm needed to accurately predict students who are entitled to scholarships. With the naïve bayes algorithm, accuracy is 77.50% in predicting scholarship recipients based on the criteria found in students. The use of genetic algorithms is done to get a more optimal level of accuracy. This is evidenced by the accuracy of 83.33%.
