"Just like electricity, Machine Learning will revolutionize our life in many ways-some of which are not even conceivable today. This book provides a thorough conceptual understanding of Machine Learning techniques and algorithms. Many of the mathematical concepts are explained in an intuitive manner. The book starts with an overview of machine learning and the underlying Mathematical and Statistical concepts before moving onto machine learning topics. It gradually builds up the depth, covering many of the present day machine learning algorithms, ending in Deep Learning and Reinforcement Learning algorithms. The book also covers some of the popular Machine Learning applications. The material in this book is agnostic to any specific programming language or hardware so that readers can try these concepts on whichever platforms they are already familiar with."

"The emphasis of the book is on the question of Why – only if why an algorithm is successful is understood, can it be properly applied, and the results trusted. Algorithms are often taught side by side without showing the similarities and differences between them. This book addresses the commonalities, and aims to give a thorough and in-depth treatment and develop intuition, while remaining concise."

"Banyaknya konferensi menyulitkan peneliti memilih konferensi berkualitas. Kemungkinan peneliti tertipu dengan konferensi predator merupakan ancaman nyata yang perlu diperhatikan. Penilaian konferensi umumnya menggunakan pakar yang membutuhkan waktu dan biaya yang tinggi. Penelitian ini fokus untuk menganalisis jika h-indeks, impact factor, jumlah dokumen, dan SJR dapat menghasilkan penilaian kualitas yang sesuai dengan penilaian manual pakar dari beberapa situs penilaian konferensi serta membandingkan hasil performanya dengan penilaian jurnal. Data yang digunakan dikumpulkan dari empat sumber situs web yang mengkalkulasi kualitas konferensi luar negeri, yaitu CORE, ERA/QUALIS, AMiner, dan ScimagoJR. Data untuk penilaian jurnal didapatkan dari Guide2Research. Variabel yang digunakan untuk penilaian adalah h-indeks, jumlah dokumen, impact factor, dan SJR. Penelitian ini menggunakan metode K-Nearest Neighbor (KNN), Support Vector Machine (SVM), Naïve Bayes, dan Decision Tree (DT).

The number of conferences makes it difficult for researchers to choose quality conferences. The possibility of researchers being fooled by predatory conferences is a real threat that deserves attention. Conference assessments generally use experts who require time and money to evaluate the conferences. This study focuses on analyzing whether h-index, impact factor, number of documents, and SJR can produce quality assessments in accordance with expert manual assessments from several conference assessment sites and compare the resulting performance with journal assessments. The data used were collected from four website sources that calculate the quality of overseas conferences, namely CORE, ERA/QUALIS, AMiner, and ScimagoJR. Data for journal assessments were obtained from Guide2Research. The variables used for the assessment are h-index, number of documents, impact factor, and SJR. This research used K-Nearest Neighbor (KNN), Support Vector Machine (SVM), Naïve Bayes, and Decision Tree (DT). KNN produced the highest accuracy value of 72.22% and the f1 score of 63.06% using Qualis data with the h-index, IF, and SJR factors."

"Penelitian ini menganalisis akurasi peramalan permintaan produk barang konsumsi cepat (FMCG) menggunakan model Machine Learning, yaitu LSTM (Long Short-Term Memory) dan SARIMAX (Seasonal AutoRegressive Integrated Moving Average with eXogenous regressors), dengan data sekunder dari April 2021 hingga April 2024 yang terdiri dari 36 observasi bulanan. Variabel dependen adalah total penjualan, sementara variabel eksogen mencakup pengeluaran per kapita, adopsi produk, proporsi penjualan dari promosi, jumlah toko yang menjual produk, dan pangsa pasar produk. Hasil menunjukkan model LSTM memiliki akurasi lebih tinggi dalam memprediksi nilai penjualan dibandingkan SARIMAX, dengan nilai Mean Absolute Percentage Error (MAPE) yang lebih rendah pada sebagian besar sampel. Analisis korelasi mengungkapkan variabel jumlah toko yang menjual produk dan adopsi produk berpengaruh signifikan terhadap nilai penjualan dalam model LSTM, sedangkan SARIMAX unggul dalam menangkap pola musiman namun memiliki MAPE lebih tinggi. Penelitian ini menyarankan penggunaan model LSTM untuk data time series yang kompleks dan tidak stasioner, sementara SARIMAX lebih cocok untuk data dengan komponen musiman yang kuat. Pemilihan model harus mempertimbangkan karakteristik data dan tujuan analisis.

This study analyzes the forecasting accuracy of fast-moving consumer goods (FMCG) demand using Machine Learning models, namely LSTM (Long Short-Term Memory) and SARIMAX (Seasonal AutoRegressive Integrated Moving Average with eXogenous regressors), utilizing secondary data from April 2021 to April 2024 with a total of 36 monthly observations. The dependent variable is sales value, while the exogenous variables include spend per buyer, product penetration, promo % of value, the number of stores selling, and market share. The results indicate that the LSTM model has higher accuracy in predicting sales value compared to the SARIMAX model, with a lower Mean Absolute Percentage Error (MAPE) for most samples. Correlation analysis reveals that the variables number of stores selling and product penetration significantly influence sales value in the LSTM model, whereas SARIMAX excels in capturing seasonal patterns but has a higher MAPE. This study recommends using the LSTM model for complex and non-stationary time series data, while SARIMAX is more suitable for data with strong seasonal components. Model selection should consider the characteristics of the data and the objectives of the analysis."

Jakarta as the big city and the capital of Indonesia that have high density rate in the work hours and days have a special rule to decrease the congestion rate in the road. One of the rules is the enforcement of odd even license plate rules that connect to the real time date. This rule is effective in decreasing the congestion rate in the major arterial roads. but there's still a loophole that makes people violate this rule, the human limited ability makes them can't always observe all the license plate. With the help of technology development in computer vision, can help to reduce the problem. Computer vision combines the video camera and computer to work side by side so it can read and detect the license plate number. Technology development also develops the computer vision ability so detection and recognition can be done with more accuracy and less time. To do this thing YOLOv7 algorithm trains a model to detect the license plate in a car and read the license plate so it can classify the license plate type (odd/even) and compare it with the research date type. This research build the prototype of detection and classifier system with machine learning and computer vision, to do the automatic odd /even license plate detection and recognition at the car in artery road. As the result of the research , the detection model made by YOLOv7 algorithm have a 86 % accuracy, and the character recognition with EasyOCR have a character error rate 3.81 %  and word error rate 11.90 % , the system prototype can run the detection and OCR in real time, the prototype can get the real time date and classified it as odd or even number, and give an alert when the detected license plate number violated the odd even rule."
