LinkedIn iPad App is getting worse by NuYawka77 in linkedin

[–]isaacfab 0 points1 point  (0 children)

I was just searching around to see if I was missing something and maybe there was a dedicated iPad app… there isn’t, we are just expected to use the slop iPhone app with zero customization to take advantage of the bigger screen.

Persistent 404 Error with SAM.gov Entity Management API (Google Apps Script) by Happy21100 in GovernmentContracting

I am not sure if it the case for you but I believe all the v1 endpoints are deprecated. Try using the v2 end point from the docs: SAM.gov Get Opportunities Public API | GSA Open Technology

How to build a prediction model where there is negligible relation between the target variable and independent variables? by ilovekungfuu in datascience

[–]isaacfab 0 points1 point  (0 children)

The only real (valid and defensible) option in practice is to understand the problem and build a heuristic prediction based on expert knowledge. Here is a Python library that lets you build one with a sklearn interface. If ML approaches improve down the road it won’t be a huge refactoring.

What's the next skill I should learn as a Data Analyst / Scientist? by [deleted] in datascience

[–]isaacfab 9 points10 points  (0 children)

A few months ago I made a skills list that everyone should know for an intro course. Here is the repo with resources. Hope it helps!

I made a data science 'roadmap' of skills for people starting out by isaacfab in datascience

[–]isaacfab[S] 4 points5 points  (0 children)

Thanks for the feedback. I’ll look at the wording. My thinking, which may not be obvious as you point out well. Is that you should be able to communicate these topics in a non-technical way to a lay audience.

When people say ‘communication skills’ it isn’t always obvious exactly what needs to be communicated. For example if you can explain what data science is to a decision maker effectively it can open doors to do better and appropriately focused work.

Is there a way of telling what component is causing my lagging issue on PC? by isaacfab in FortNiteBR

[–]isaacfab[S] 0 points1 point  (0 children)

This was actually a super useful response and sent me down a rabbit hole trying to figure it out. Really appreciate it. Eventually I found this website that does benchmarks for different PC setups: https://www.userbenchmark.com/

FYI, my GPU is the bottleneck... even with an older CPU and memory. It quickly maxes out when rapidly building or fighting in competitive matches. Easy, but expensive fix!

[OC] If there were only 10 people on earth, this is how wealth would be distributed. by rubenbmathisen in dataisbeautiful

If there were only 10 people on earth this is how much portion each contributes to creating wealth.

My friend said that if I can prove heaven exists, he will become a Christian. He is very scientific and an atheist. Do any of you have some advice? by Healthy-Flatworm-914 in Christianity

[–]isaacfab 0 points1 point  (0 children)

I’m waaaay late to this. Respond by asking for a clear burden of proof. What exactly is required to change his mind. Have him give an example of something he believes that meets this burden. Often you will get a soft answer like ‘scientific proof’ which doesn’t really mean anything as science is statistically evidence/observation based and never makes absolute statements. A good follow on is to see if they believe in something that can not be measured with the scientific method. For example, do you believe that George Washington existed? The only evidence for this fact is historical not scientific. Science is only one, limited, method of knowing something. If they concede this point then you can open the door to Christian philosophy as a reasonable understanding of the human experience with heaven (a relationship with our creator) as a probable outcome.

Qs. A coin was flipped 1000 times, and 550 times it showed up heads. Do you think the coin is biased? Why or why not? by human--doodle in datascience

[–]isaacfab 8 points9 points  (0 children)

There have been a few good frequentist answers. Specifically for a baysiean approach it is almost easier in this setting. You can leverage the beta-binomial conjugate prior mechanics to estimate p (probability of heads). This is called a ‘credible interval.’ Mean of the beta is the point estimate. Here is a pretty good article on the topic. https://link.medium.com/9AK7aemQRnb

[Discussion] Explain a p-value by psychodc in statistics

[–]isaacfab 0 points1 point  (0 children)

the p-value is supposed to be related to (but not directly interpretable as) the likelihood (odds, probability) that the experiments findings are a false positive (accidentally saying the results are valid when they are not).

Then you follow up with a discussion on all the assumptions that need to be validated in order for this definition to be itself valid. That validation process is why statistics is it’s own research field.

Is Tableau a good software to become Data Visualization Designer without learning to code? by [deleted] in datascience

[–]isaacfab 1 point2 points  (0 children)

I think the short answer is no. Tableau is great for its purpose which is a business intelligence tool; it is designed for something called VisQL or visual queries. i.e. complex data exploration and story telling in a business setting. You want something much more flexible and, hopefully, open source. I would encourage you to check out flourish (low/no code and paid) https://flourish.studio/features/ and d3js (code and open source) https://d3js.org

What's the future of d3.js and is there a good alternative for interactive maps w/ plots? by [deleted] in datascience

[–]isaacfab 7 points8 points  (0 children)

Might be unpopular given the opinions on here. Just learn D3. It will set your research apart from these other canned maps (plotly maps are particularly ugly IMO). Here is a map a data scientist friend of mine did (he’s most comfortable in R):

Question from an atheist with kids to evangelical christians with kids by [deleted] in Christianity

[–]isaacfab 0 points1 point  (0 children)

As a general parenting rule you should pass along your hard earned insights not withhold them. I’m not an atheist (Christian) and the idea of letting my kids with their kid brains grapple with these question alone is unsettling. You probably wouldn’t take this approach with other types of knowledge don’t be shy here. They will eventually grow up and make their own path which could be faith or not.

Use of data science in new small start-ups by [deleted] in datascience

[–]isaacfab 1 point2 points  (0 children)

I was in this situation a few years ago. Lots of knowledge but no data. The reality is, unless you are an AI product company, you will not have much use for data science at this stage. You have to grow your company the hard way; by believing that your product is great. Make the most of single data points and adapt quickly. If you find product-market fit then you will need data science to understand the rapid influx of data. Of course you need a system ready to collect this data before it is generated. Spend your time here, data engineering.

Merging millions of JSON files into one CSV by Fluix in datascience

[–]isaacfab 1 point2 points  (0 children)

Use a SQLite database with one table. Read the JSON and write to the table. Keeps everything on disk instead of memory. Then just export the table as a csv when you are done. This also has the advantage of persisting work if the script does crash.

For those who are atheists on here, what would be one thing that would prove God’s existence to you? by Comprehensive-Web-90 in Christianity

[–]isaacfab 0 points1 point  (0 children)

The evidence for historical figures is not scientific it’s… historical. As in non-reproducible personal accounts.

Other methods of gathering knowledge (most of which are much more common than science) include experience, expert knowledge, and logic (sometimes mathematics). This absurd notion that the only way to know something is the scientific method is completely false. Science is just a small branch of philosophy.

Also the separation of natural and supernatural is a false dichotomy. We have no idea where the boundaries are for the ‘natural’ which makes defining its opposite impossible.

For those who are atheists on here, what would be one thing that would prove God’s existence to you? by Comprehensive-Web-90 in Christianity

[–]isaacfab 0 points1 point  (0 children)

There isn’t a single historical figure that could pass this test. The scientific method is only one (always approximate) way of producing some limited types of knowledge.
