Is there more questions on a voting ballot than there are questions on the SAT? How the can they do it in a somewhat timely manner but our government can't grasp the concept of how to do it...still, today?

STOP THIS SHIT, SIT DOWN AND SHUT UP...PLEASE!

1/20...
Stop asking stupid questions or you'll continue to get stupid answers.

Feed us the data that matters so we can figure this out the right way.

#ProblemSolving101 using the #ScientificMethod.
If facts tend to change on their way to finding the truth...then give us the facts and lets figure this out for ourselves once and for all.

Stop censoring the truths and facts that are available.

I spent the weekend putting together a "Meta RMarkdown" blog post!

4 R Markdown Strategies:

1 - Literate Programming
2 - Data Product
3 - Control Document
4 - Template

themockup.blog/posts/2020-07-…

#rstats #datascience #tidyverse
1 - Literate Programming

Use RMarkdown like a reproducible scientific notebook, capturing code, comments, and specific outputs in a output document.

All in plain text that is easily human-readable in version control!
2 - Data Product

Generate all sorts of fancy outputs from RMarkdown, such as:
- Presentations (Powerpoint or web native like remark.js)
- Dashboards w/ flexdashboards
- Reports as HTML, PDF, Word, etc
- Entire websites w/ blogdown, hugodown, distill

I am really thrilled to release #AutoSpill onto @biorxivpreprint. It is a novel method for applying compensation to #flowcytometry data, which reduces the error by ~100,000-fold. It is thanks to AutoSpill that we can push machines to their max colours

biorxiv.org/content/10.110…
#AutoSpill is a beautiful example of what #maths can add to #immunology, led by the talented Dr Carlos Roca.

It has really open up my eyes to the potential of #computationalbiology, and is the reason why we have a new #datascience position available:

babrahaminstitute.livevacancies.co.uk/#/job/details/…
So how does #AutoSpill work? If you just want to compensate your data, simply upload your single colour controls to autospill.vib.be and then copy the spillover matrix to your #flowcytometry program of choice

@CarlyEWhyte can walk you through the whole process in <2'

In January, I wrote a Python script to query the @USAJOBS API every day for federal job announcements containing any of eight keywords related to #datascience. Almost 6 months later, I have amassed more than 500 job announcements and want to explore what I've collected. A thread:
First, these are the eight keywords I searched for and the number of announcements in which they appeared in the title, qualifications, or duties:
The problem with looking for #datascience jobs on USAJobs is that there (currently) is no data science job series so you have to wade through other occupational series. These are the 10 most common job series that contained any of the keywords.

A few months ago I wrote a very long blog for @CommitteeSysmus on advice that I wish I would have heard when I was a graduate student about getting a non-academic job.

sites.google.com/view/sysmus/bl…

I'll thread the major points below because it's a long one (4K words)
There are a lot of resources on how to keep going on in academia, but as we all know, we can't all immediately go from PhD to more academia (AND this was all originally written pre-COVID) but there's not a lot of good resources to help people prepare for that as a student.
So I wanted to just pass on many words of wisdom that I think I would have found helpful a few years ago (esp since my first job out of PhD was helping people land junior #datascience jobs) and not just say what to do (ewww) but rather my thoughts on why.

Today's thread - by @pingali - is about making #MachineLearning projects successful. Links back to the first session of making #DataScience work by @scribbledata hasgeek.com/fifthelephant/… (1/8) Learn more by joining The Fifth Elephant on hasgeek.com/fifthelephant
@pingali @scribbledata Framing: Formulating a good problem is the most important step. What is 'good' depends on the context. Mature companies require optimal solutions. Sometimes, framing can be good enough but something that can be pulled back. Take #risks, with guard rails in place. (2/8) Join The Fifth Elephant to participate: hasgeek.com/fifthelephant
@pingali @scribbledata Buy-in: #DataScience has ambiguity. Communicating is
critical - define goals of communication; who you are communicating with is important. Link data science outcomes to business outcomes. Understand incentives and motives of other stakeholders. Be empathetic. (3/8) Subscribe to The Fifth Elephant on hasgeek.com/fifthelephant to join.

As #bioinformatician #biostatistician #DataScientist, have you ever felt you've done lots of work, yet achieved nothing? here is how to change that! A thread 👇 1/n
1 - #document rigorously your computing work - same as bench scientists do on experiments. Document your initial thoughts on data, your decisions, tests, issues, how you solved them, how you tried various tools, how you picked one over others. These are all *achievements*. n/1
2 - #track your tasks and efforts - make it quantitative. Write a weekly checklist on GitHub wiki; update and check it off at the end of a day. Version control your codes; push meaningful commits. Be aware of your time spent on each task. Numbers may be boring, but effective. 2/n

The next time you visit Yellowstone National Park to check out the Old Faithful geyser, know that if you wait for too long for the geyser to go off... you are likely to witness a longer eruption.
We use a cars dataset of car models with features such as horsepower and cylinders (& 5 more). We perform dimensionality reduction on this data & find out that European/Japanese cars cluster together whereas American cars form their own two clusters. But why? I'd love to find out

Had fun live-streaming a chat yesterday with @IcahnMountSinai Director of Bioinformatics @AviMaayan

Before our @tidybiology code along, Avi dropped some words of wisdom 👇

On approaches to science:

Avi Mayan builds tools to enable biological discovery. He wants to figure out “how cells work”

He is gene-agnostic & disease-agnostic, meaning he can follow science wherever it takes him

This is a tremendous advantage for genuine & impactful discovery
On Data science:

#datascience infuses computation in biology, statistics, topology (networks), dynamic modeling

All providing a data driven approach

For his PhD, Avi tried reading 1000+ papers to understand cell signaling networks

“It was quite daunting, and it didn’t work"

Data is the new buzz word and it is made its way into the Ag sector,helping farmers make smart decisions in order to increase productivity.
Here are some of the benefits of data science

Data Science grants the farmer access to databases collected from examining the weather in
order to come to conclusions that would improve productivity.

Also in gathering data from the soil like uptake rate, land type etc, recommendations can be made as regards the optimal need of the soil for certain nutrients.

In modern agriculture, advanced algorithms are used to
identify the patterns and behavior of nature that helps in forecasting the invasion of pests and the spread of microscopic diseases.

What's the difference between a Data Engineer , a Data Analyst & a Data Scientist?

If you want to make sure you don’t lose your job in the next five years, you probably want to know something about Big Data, or even switch to a data-related career.
#Thread
#DataScience #Data
You don’t need to be an excellent statistician or a high-class mathematician to work in data science or analytics, nor do you need a lot of prior programming knowledge.
- Dr. Rebecca Pope (Head, Data Science d Engineering at KPMG)

#DataScience #Data #DataAnalyst #Statistics
However, you do need an interest in statistics, you do need to be willing to learn how to code, and you do need to know how to do some high level mathematical operations. Data scientists are not just statisticians.

Blogs are great tools to showcase your work as a machine learning engineer. By writing blog posts, you better describe your projects and results. Also, it makes your projects discoverable by search engines.

#MachineLearning #DataScience
A practical way to start blogging is to use tools like @Medium or @ThePracticalDev. You don't have to waste time with details like domains, templates, or hosting. You have to focus only in writing.

If you are diving into Machine Learning some time after school, then you need a brush on Calculus. Probably you won't have the time to take a full course on Calculus, so you have to focus on the essential topics for MachineLearning. Check them:
1) Functions: you need to be familiar with functions, you must explain what a function is, and you need to be familiar with some of the main types of functions, like linear, quadratic, exponential, logarithmic and trigonometric functions
2) Derivatives: learn what is a derivative and how to find the derivatives of simple functions. Don't spend too much time on finding derivatives of complicated functions. Learn the basics and learn how to use numerical software to find derivatives.
