50+ Data Science, Machine Learning Cheat Sheets, updated. This post updates a previous very popular post 50+ Data Science, Machine Learning Cheat Sheets by Bhavya Geethika.
If we missed some popular cheat sheets, add them in the comments below. Cheatsheets on Python, R and Numpy, Scipy, Pandas Data science is a multi-disciplinary field. Thus, there are thousands of packages and hundreds of programming functions out there in the data science world! An aspiring data enthusiast need not know all. Mastering Data science involves understanding of statistics, mathematics, programming knowledge especially in R, Python & SQL and then deploying a combination of all these to derive insights using the business understanding & a human instinct—that drives decisions. Here are the cheat sheets by category: Cheat sheets for Python: Python is a popular choice for beginners, yet still powerful enough to back some of the world’s most popular products and applications.
Cheat sheets for R: At cran.r-project.org: At Rstudio.com: Others: Cheat sheets for MySQL & SQL: Forecasting - Predicting future values with a regression model. Analytics Vidhya. Philosophy of mathematics - Wikipedia. The terms philosophy of mathematics and mathematical philosophy are frequently used interchangeably. The latter, however, may be used to refer to several other areas of study.
One refers to a project of formalizing a philosophical subject matter, say, aesthetics, ethics, logic, metaphysics, or theology, in a purportedly more exact and rigorous form, as for example the labors of scholastic theologians, or the systematic aims of Leibniz and Spinoza. Another refers to the working philosophy of an individual practitioner or a like-minded community of practicing mathematicians. Additionally, some understand the term "mathematical philosophy" to be an allusion to the approach to the foundations of mathematics taken by Bertrand Russell in his books The Principles of Mathematics and Introduction to Mathematical Philosophy. Recurrent themes Recurrent themes include: What is the role of Mankind in developing mathematics? History The origin of mathematics is subject to argument.

Anomaly detection. Visualizing Algorithms. The power of the unaided mind is highly overrated… The real powers come from devising external aids that enhance cognitive abilities.
—Donald Norman Algorithms are a fascinating use case for visualization. To visualize an algorithm, we don’t merely fit data to a chart; there is no primary dataset. Instead there are logical rules that describe behavior. This may be why algorithm visualizations are so unusual, as designers experiment with novel forms to better communicate. But algorithms are also a reminder that visualization is more than a tool for finding patterns in data.
#Sampling Before I can explain the first algorithm, I first need to explain the problem it addresses. Light — electromagnetic radiation — the light emanating from this screen, traveling through the air, focused by your lens and projected onto the retina — is a continuous signal. This reduction process is called sampling, and it is essential to vision. Sampling is made difficult by competing goals. Here’s how it works:
