ChatGPT is like having a super smart friend who can answer any question you ask. This friend is made by very smart people using computers and lots of information from books and websites. They taught the computer how to have a conversation with you by using what they learned.

When you ask ChatGPT a question, it uses its big brain to find the answer and then types it back to you. ChatGPT can answer questions about anything, like animals, places, and even math problems. It can also talk with you and have a conversation just like you would with a real friend.

It’s important to be nice to ChatGPT and ask it questions that are easy to understand. Try asking simple questions and give it time to think and find the answer. ChatGPT is still learning, so sometimes it might not know the answer or might make a mistake, but that’s okay! Just ask another question and it will try its best to find the answer for you.

ChatGPT is a cool tool that can help you learn new things and have fun conversations. Just remember, it’s not a real friend and doesn’t have feelings, so treat it nicely and always use good manners when you talk to it.

Yo, listen up data scientists, you need to stay ahead of the game, know what’s good for your career and the future of the field. AI technology is poppin’ off, and ChatGPT is one of the leading models out there. You best believe you gotta pay close attention to it and keep up with the latest developments.

First of all, ChatGPT and AI technology is transforming the way we do things. In the near future, AI-powered models like ChatGPT will be a critical tool in solving complex data science challenges and automating tedious tasks. This is the way the industry is heading, so you wanna be ahead of the curve.

Second, being well-versed in AI technologies, like ChatGPT, can help you stand out in a competitive job market. As AI becomes more widely adopted, demand for data scientists with AI skills will skyrocket. By paying close attention to ChatGPT and emerging AI technologies, you’ll be better positioned to meet the needs of future employers.

Finally, as AI technologies continue to evolve, the field of data science and machine learning will face new and exciting challenges. By paying close attention to ChatGPT and other AI models, data scientists can stay ahead of the curve and better prepare themselves to tackle these challenges.

So, in short, if you’re a data scientist or professional, it’s critical that you stay ahead of the game and pay close attention to ChatGPT and emerging AI technologies. This will help you stay relevant, advance your career, and be better prepared for the future of data science. Keep it real, and stay ahead of the game.

A coworker recently asked me to explain how one goes about building a credit risk model. It’s something my company does a lot of, but apparently it’s not taught during new hire on-boarding. Also, it made me think, how would I actually explain the process end-to-end to someone interested in our industry but not a practitioner? Curious, I searched Google in case anyone had already done so, and of course someone else had! So, here’s a quite impressive deep-dive into credit risk modelling thanks to Natasha Mashanovich, Senior Data Scientist at World Programming: Credit Scoring: The Development Process from End to End

This is a ten-part series of blog posts describing the entire process. Her company seems to be some sort of SAS competitor, and I am not endorsing her product or company in any way. That said, her write up is pretty tool-agnostic and pretty general, so it is worth a read if you are interested.

Personally, I would create a modelling pipeline in python / pyspark (since we deal with large data sets) in a cloud environment (like AWS) instead of SAS, but not everyone in the financial services industry has moved to the cloud yet. I hope you find the link to be helpful…

One day I got curious… what if I programmed my computer to track the fish swimming in my fish tank? That led me to tinkering with an open source software library called OpenCV. I fiddled around with the settings, tried a few things, and saved the output as a video, seen below. There’s a lot of research in computer science around object recognition and identification … this mini-project was just an attempt to have some fun poking around with some “older” computer vision technologies. Let me know what you think!

 

 

Context

Approximately 10% of American households have fish as pets.
It is estimated that 95% of fish deaths can be attributed to improper housing or nutrition. Many times fish are sold or given away without any guidance to the new pet owner, such as goldfish giveaways at carnivals or at birthdays. Some fish have myths associated with them, such as the betta fish (siamese fighting fish) that supposedly can live in dirty water in small bowls.

AqAdvisor.com is a website that helps aquarists plan how to stock their fish tank. Users specify their tank size, their filtration, and what fish they intend to keep in the tank. The site will calculate the stocking level and filtration capacity given the inputs. This is a useful tool to get a rough estimate on a fish tank’s stocking level, it even lets you know whether the fish are compatible with one another, if you have more than one species in the tank. AqAdvisor is sometimes criticized for “not being accurate”, so the output generated should be not be treated as gospel; nonetheless, it gives a reasonable starting point, and is generally very useful for beginner fishkeepers.

Why I created this tool

I started using AqAdvisor and got annoyed at the archaic design. It’s not a RESTful API, it’s a clunky web site that takes a while to load. I was doing lots of research and found myself wanting a better useful experience. I also had some free time on my hands one long holiday weekend so I decided to give myself a little programming exercise of creating a python API to the site.

How to use the tool

The easiest way to use the tool is to use the ipython notebook as a starting point. First, create a stocking, then a tank, and then make a call to the AqAdvisor service. Because of the clunky web interface, multiple calls to AqAdvisor.com must be made if you want to have more than one fish species in a tank (as is would be the case for a community tank). The auto-generated AqAdvisor URL will be printed for each call out to the website. This is useful in case you want to jump over to the web UI, you can just copy and paste the URL into your web browser and continue from there.

Use the common (English) name for the fish you are looking for. PyAqAdvisor will do a “fuzzy match” to AqAdvisor’s species list and match the closet one. This way you can specify your stocking list as “cardinal tetra” and not worry about the scientic name.

Please look at examples/example.py and examples/example.ipynb for more information.

Here’s an example of how easy it use the new API:

from pyaqadvisor import Tank, Stocking

if __name__ == '__main__':

  stocking = Stocking().add('cardinal tetra', 5)\
   .add('panda cory', 6)\
   .add('lemon_tetra', 12)\
   .add('pearl gourami', 4)

  print "My user-specified stocking is: ", stocking
  print "I translate this into: ", stocking.aqadvisor_stock_list

  t = Tank('55g').add_filter("AquaClear 30").add_stocking(stocking)
  print "Aqadvisor tells me: ",
  print t.get_stocking_level()

• PyAqAdvisor currently only works for freshwater fish species. If you are interested in saltwater fish, please contact me.
