Given a Gaussian function that depicts the well-known bell-shaped curve.

$$p(x)=e^{-x^{2}/2},\quad x\in (-\infty ,\infty )$$We can compute the integral.

$$\int _{-\infty }^{\infty }p(x)\,dx=\int _{-\infty }^{\infty }e^{-x^{2}/2}\,dx={\sqrt {2\pi \,}}.$$Dividing the Gaussian function by …

Inspecting a data set is usually not a linear process, but involves iterative refinement of the initial assumptions and question. One might have an initial question but after taking a look at the data set realize that it requires multiple preprocessing steps before it can be used to address the …

The Broadcasting mechanism in NumPy is usually introduced by explaining the relevant rules.

Another perspective is to look at the topic from a mathematical viewpoint.

The initial example is the addition of a function and a constant.

$$f:= \sin{} + C$$The authors argue that this is not proper mathematical notation …

Here I will write about things related to data science.

For now this site is just a mockup. I will probably use a static site generator and Drafts to write postings.
