From now on, let $\vec{\mathbf{x}} = (x^1, \cdots, x^n) \in \mathbb{R}$ and $\overrightarrow{\mathbf{x}_0} = (x_0^1, \cdots, x^n_0) \in \mathbb{R}^n$. Also let $f_i (\vec{x}) = \frac{\partial f}{\partial x^i}$ be the $i$-th partial derivative.

This talk aims to discuss, demystify and crack open various data formats used by meteorological agencies. Formats encountered along the way includes curiously formatted comma separated files, xml (blergh), json as well as n-dimensional data — all using data available ...

The analysis will start by looking at just the dataset itself. We'll look at:

The system temperature, $T_\mathrm{sys}$, is a property of the receiver, which determines the base noise level. It depends on the receiver noise itself, but also has conributions from ground and atmosphere, as well as astronomical background (Galactic continuum, CMB). The ...

Standardise the inputs and outputs so that it is easier to train. I have't saved the mean and standard deviations, but you should.

It will be like being drunk, except that your it will be my Python interpretor and not me !

As an example, consider two groups of runners. The first group of runners trains regularly and is in good shape. The second group of runners does not train but still enjoy running occaisionally. You measure how fast everyone can run ...

Fermat's library, @fermatslibrary , posted on twitter a gif https://twitter.com/fermatslibrary/status/862659602776805379 illustrating eight points moving inside a circle. No explanation of the motion was given. Here I reproduce it via Python Plotly.

I'm still wrapping my brain around pandas and I'm sure there are other ways to achieve similar results more efficiently. Let me know!

プログラミング学習者の皆さんであれば、Javaと呼ばれるプログラミング言語があることはご存知でしょう。では、名前の似ているJavaとJavaScriptは何か関係があるのでしょうか？ 答えは 全く関係ありません 。 JavaScriptは、1990年代にNetscape社によってLiveScriptという名前で開発されました。当時Netscape社と業務提携していたSun Microsystems社の開発したJavaという言語が大きく流行ったため、JavaScriptという名前に変更されました。そのため、JavaとJavaScriptは名前は似ていても中身は全く別物です。

This is the referendum result as a function of constituency (the actual wards were not constituencies, so this has been estimated: https://docs.google.com/spreadsheets/d/1wTK5dV2_YjCMsUYlwg0l48uWWf44sKgG8uFVMv5OWlA/ )
