ADABOOST

AdaBoost This blog post will provide you with a comprehensive overview of Adaboost, exploring the theory behind this probabilistic algorithm and demonstrating its implementation using Python libraries. Dive in to uncover the advantages and disadvantages of neural network, as well as its real-world applications across various domains. With that, enjoy your journey in QDO! What is  Adaboost AdaBoost (Adaptive Boosting) is an ensemble learning technique that combines multiple weak classifiers (often decision trees) to create a strong classifier. It works by training the weak classifiers sequentially, giving more weight to misclassified instances at each step so that subsequent classifiers focus more on the harder cases. The final prediction is made by combining the weighted votes of all weak classifiers. AdaBoost is effective at reducing bias and variance, and it’s particularly good for binary classification problems. However, it can be sensitive to noisy data and outliers. Concepts o...

LINEAR REGRESSION

 LINEAR REGRESSION Figure 1: Linear regression figure This blogpost will walk you through the concept of linear regression which is another machine learning model under the regression category of supervised learning. Introducing the parameters that you can turn while applying the logistic regression as well as the factors that play a significant impact upon the performance of the linear regression. What is linear regression Linear regression is a machine learning algorithm that could be used in predictive analysis. From predicting prices of houses to sales forecasting, linear regression is undoubtedly the first choice to many data scientists to implement within the dataset. In short, linear regression involves plotting your data on the graph base on the x and y coordinate and proceed to draw the best fit line upon the graph. The best fit line will be used as a reference to predict the independent variable in the future. However, do you have the skill to conduct a excellent analysis...

LOGISTIC REGRESSION

 LOGISTIC REGRESSION Figure 1: Logistic regression This blogpost will provide you an overview of logistic regression, the theory behind the algorithm of logistic regression and its implementation using python libraries. Dive in to discover the advantages and disadvantages of logistic regression as well as its real life applications. With that, enjoy your journey in QDO. WHAT IS LOGISTIC REGRESSION Figure 2: Logistic regression Logistic regression is considered as one of the most commonly used machine learning algorithm in the field of data science and it is used as a predictive model to predict the outcome base on the input variables feed into the model. This model is most suitable for binary classification tasks in which the dependent variable is categorical and typically represents two classes. For example: yes/no 0/1 true/false The visualization of the results of logistic regression would be a graph with a line that is in form of the shape of S, which is what makes logistic regr...
