This note is used to show the compoents I created to use in this site. It's for me only. I use it as a reference when I wanna create some components for the notes.

👉 Note: For me only (This is another technical note used for this site only).

This uses shortcode {% icon "draft" %}.

This uses shortcode {% icon "idea" %}.

This uses shortcode {% icon "warning" %}. I wanna make a very long sentence to see how this icon will be placed in the paragraph.

This uses shortcode {% icon "success" %}.

This uses shortcode {% icon "time" %}.

Check line eleventyConfig.addShortcode("icon" in .eleventy.js for more icon names.

\underbrace{SDR(S,O)}_{\text{Standard Deviation Reduction}}= \underbrace{SD(S)}_{\text{SD before split}}- \underbrace{\sum_j P(O_j | S) \times SD(S,O_j)}_{\text{weighted SD after split}}

Inside a list

Calculate the Standard Deviation ( $SD$ ) of the current node (let's say $S$ , parent node) by using MSE or MAE,
$\begin{aligned}SD(S) &= \frac{1}{n} \sum_{i=1}^{n} (y_i - \bar{y}_i)^2, \\\text{or } SD(S) &= \frac{1}{n}\sum_{i=1}^n \vert y_i - \bar{y}_i \vert,\end{aligned}$
where $y_i\in$ the target values (Hours Played in the above example), $\bar{y}=\frac{\Sigma y}{n}$ is the mean value and $n$ is the number of examples in this node.
Calculate the Standard Deviation Reduction (SDR) after splitting node $S$ on each attribute (for example, consider attribute $O$ ). The attribute w.r.t. the biggest SDR will be chosen!
$\underbrace{SDR(S,O)}_{\text{Standard Deviation Reduction}}= \underbrace{SD(S)}_{\text{SD before split}}- \underbrace{\sum_j P(O_j | S) \times SD(S,O_j)}_{\text{weighted SD after split}}$
where $j \in$ number of different properties in $O$ and $P(O_j)$ is the propability of property $O_j$ in $O$ . Note that, $SD(S,O_j)$ means the SD of node $O_j$ which is also a child of node $S$ .
After splitting, we have new child nodes. Each of them becomes a new parent node in the next step. Go back to step 1
