The Role of Charities vs. Government

2. Charities should not exist. It is the responsibility of the government to provide for all in society.

Some people argue that charities should not exist because governments should be responsible for ensuring that everyone’s needs are met. While this idea might seem ideal, I believe that charities are necessary to complement the work of governments. Governments are often limited by bureaucracy or budget constraints, which can prevent them from addressing all social issues effectively.

Charities step in to provide support where it is most needed, such as:

• Offering disaster relief
• Helping vulnerable groups

Moreover, charities allow individuals and communities to take part in social causes, fostering solidarity... Continue reading "Why We Need Charities and Youth Volunteering" »

Support Vector Machines (SVM)

A support vector machine is a supervised method for classification or regression that seeks a boundary in a high-dimensional space which separates classes with the widest possible margin. The training process involves choosing a boundary that maximizes the distance to the nearest training points, known as support vectors. When data are not perfectly separable, slack variables can be introduced to allow some misclassifications or margin violations while balancing margin maximization and classification accuracy. A kernel is a special function that effectively maps data into higher-dimensional spaces without doing the mapping explicitly; it lets the support vector machine handle nonlinear relationships by measuring...

Finding the Point of Intersection

Method 1: Elimination

1. Use multiplication to get one variable having the same numbers in both equations (they can have different signs).
2. If the signs for the variables are the same, subtract the two equations; otherwise, add them.
3. Substitute the answer into an original equation and solve.

Method 2: Substitution

1. Isolate one variable in one equation.
2. Substitute into the other equation.
3. Solve.
4. Substitute the answer into the original and solve.
