In this book, you will implement two data science projects using Scikit-Learn, Scipy, and other libraries with Python GUI.
In chapter 1, you will learn how to use Scikit-Learn, Scipy, and other libraries to perform how to predict traffic (number of vehicles) in four different junctions using Traffic Prediction Dataset (https://viviansiahaan.blogspot.com/2023/06/step-by-step-project-based-tutorials.html). This dataset contains 48.1k (48120) observations of the number of vehicles each hour in four different junctions: 1) DateTime; 2) Juction; 3) Vehicles; and 4) ID. Here's the outline of the steps involved in predicting traffic:
Dataset Preparation: Extract the dataset files to a local folder. Import the necessary libraries, such as pandas and numpy. Load the dataset into a pandas DataFrame. Exploratory Data Analysis (EDA). Explore the dataset to understand its structure and characteristics. Check for missing values or anomalies in the data. Examine the distribution of the target variable (number of vehicles). Visualize the data using plots or graphs to gain insights into the patterns and trends.; Data Preprocessing: Convert the DateTime column to a datetime data type for easier manipulation. Extract additional features from the DateTime column, such as hour, day of the week, month, etc., which might be relevant for traffic prediction. Encode categorical variables, such as Junction, using one-hot encoding or label encoding. Split the dataset into training and testing sets for model evaluation.; Feature Selection/Engineering: Perform feature selection techniques, such as correlation analysis or feature importance, to identify the most relevant features for traffic prediction. Engineer new features that might capture underlying patterns or relationships in the data, such as lagged variables or rolling averages.; Model Selection and Training: Choose an appropriate machine learning model for traffic prediction, such as linear regression, decision trees, random forests, or gradient boosting. Split the data into input features (X) and target variable (y). Split the data further into training and testing sets. Fit the chosen model to the training data. Evaluate the model's performance using appropriate evaluation metrics (e.g., mean squared error, R-squared). Model Evaluation and Hyperparameter Tuning. Assess the model's performance on the testing set. Tune the hyperparameters of the chosen model to improve its performance. Use techniques like grid search or randomized search to find the optimal hyperparameters.; Model Deployment and Prediction: Once satisfied with the model's performance, retrain it on the entire dataset (including the testing set). Save the trained model for future use. Utilize the model to make predictions on new, unseen data for traffic prediction.
In chapter 2, you will learn how to use Scikit-Learn, NumPy, Pandas, and other libraries to perform how to analyze and predict heart attack using Heart Attack Analysis & Prediction Dataset (https://viviansiahaan.blogspot.com/2023/06/step-by-step-project-based-tutorials.html). Following are the outline steps for analyzing and predicting heart attacks using the Heart Attack Analysis & Prediction Dataset. Introduction and Dataset Description: Provide an introduction to the topic of heart attack analysis and prediction. Briefly explain the dataset's source and its features, such as age, sex, blood pressure, cholesterol levels, etc.; Data Loading: Explain how to load the Heart Attack Analysis & Prediction Dataset into your Python environment using libraries like Pandas. You can mention that the dataset should be in a CSV format and demonstrate how to load it.; Data Exploration: Describe the importance of exploring the dataset before analysis. Show how to examine the dataset's structure, check for missing values, understand the statistical summary, and visualize the data using plots or charts.; Data Preprocessing: Explain the steps required to preprocess the dataset before feeding it into a machine learning model. This may include handling missing values, encoding categorical variables, scaling numerical features, and dealing with any other necessary data transformations.; Data Splitting: Describe how to split the preprocessed data into training and testing sets. Emphasize the importance of having separate data for training and evaluation to assess the model's performance accurately.; Model Building and Training: Explain how to choose an appropriate machine learning algorithm for heart attack prediction and how to build a model using libraries like Scikit-Learn. Outline the steps involved in training the model on the training dataset.; Model Evaluation: Describe how to evaluate the trained model's performance using appropriate evaluation metrics, such as accuracy, precision, recall, and F1 score. Demonstrate how to interpret the evaluation results and assess the model's predictive capabilities.; Predictions on New Data: Explain how to use the trained model to make predictions on new, unseen data. Demonstrate the process of feeding new data to the model and obtaining predictions for heart attack risk.

Rismon Hasiholan Sianipar was born in Pematang Siantar, in 1994. After graduating from SMAN 3 Pematang Siantar 3, the writer traveled to the city of Jogjakarta. In 1998 and 2001 the author completed his Bachelor of Engineering (S.T) and Master of Engineering (M.T) education in the Electrical Engineering of Gadjah Mada University, under the guidance of Prof. Dr. Adhi Soesanto and Prof. Dr. Thomas Sri Widodo, focusing on research on non-stationary signals by analyzing their energy using time-frequency maps. Because of its non-stationary nature, the distribution of signal energy becomes very dynamic on a time-frequency map. By mapping the distribution of energy in the time-frequency field using discrete wavelet transformations, one can design non-linear filters so that they can analyze the pattern of the data contained in it. In 2003, the author received a Monbukagakusho scholarship from the Japanese Government. In 2005 and 2008, he completed his Master of Engineering (M.Eng) and Doctor of Engineering (Dr.Eng) education at Yamaguchi University, under the guidance of Prof. Dr. Hidetoshi Miike. Both the master's thesis and his doctoral thesis, R.H. Sianipar combines SR-FHN (Stochastic Resonance Fitzhugh-Nagumo) filter strength with cryptosystem ECC (elliptic curve cryptography) 4096-bit both to suppress noise in digital images and digital video and maintain its authenticity. The results of this study have been documented in international scientific journals and officially patented in Japan. One of the patents was published in Japan with a registration number 2008-009549. He is active in collaborating with several universities and research institutions in Japan, particularly in the fields of cryptography, cryptanalysis and audio / image / video digital forensics. R.H. Sianipar also has experience in conducting code-breaking methods (cryptanalysis) on a number of intelligence data that are the object of research studies in Japan. R.H. Sianipar has a number of Japanese patents, and has written a number of national / international scientific articles, and dozens of national books. R.H. Sianipar has also participated in a number of workshops related to cryptography, cryptanalysis, digital watermarking, and digital forensics. In a number of workshops, R.H.
