Im 35 years old, and I just started my Data Science journey by starting college this semester. Been an aircraft mechanic for my entire adult life and been looking for a change for years now and you inspired me to finally pursue Data science. Thank You Ken, I'll be tuning into your channel just to keep my 'ear to the ground' in this exciting field. Also, not sure if you spoke on this before, but what laptop do you recommend for data science? Thanks Buddy and keep up the good work!

[@KenJee_ds]

This is awesome! Excited to hear where your journey takes you! I personally use a Z book studio from HP, but to be honest, I think almost any computer will work these days. A huge portion of data science can be done on the cloud through google colab, kaggle, or deepnote. This lets you use their compute power rather than the one on your local machine. Their offerings again are free and are plenty for those getting started.

If you want a role where you want to work only with AI and heavy duty programming go for a machine learning engineer job, if you want to do statistics and sometimes classic ML and analyze data go for a data scientist job. Working as a ML engineer you spend way more time reviewing and maintaining code (so it's more SE from one side), you use python for model development and c++/java for production (the role is building AI products, so you are all day reviewing, extracting and preprocessing data to then training ML models, evaluate them and match required KPIs) In the other hand, data scientists positions offer what is described in the video: statistics and data preparation (engineering) and classic ML, there is more flexibility regarding tools and programming languages, and the final purpose is bringing value in a business perspective with the projects you have For example, In ML engineering you get assigned some set of models that you have to maintain and improve, in data scientist positions you get several projects that constantly change. Both roles have their advantages and interesting scopes I have been in both, my background is in statistics and I have been working as ML engineer in computer vision in the automotive industry for the last 3 years. Personally, I can say ML engineering is more fun, even more in start ups where you feel you bring a lot of value with your ideas about crazy AI methods

[@KenJee_ds]

agreed!

[@ChocolateMilkCultLeader]

One of the most important things that I wish more people would do is documentation. Of datasets, sources, code, rationale etc. I often have to spend a long time on the dataset exploration phase of the project and trying to figure out things. Everything would be much smoother if people created detailed documents on the different Datasets, how things are collected, what features are used, distributions etc

[@KenJee_ds]

Can't believe I left that one out! Great call!

[@ChocolateMilkCultLeader]

@@KenJee_ds this is something I've been frustrated with recently. I often have companies reach out and dump projects onto me. But because of the lack of documentation I end up wasting a lot of time with the details of the dataset. It would be avoided if documentation was stresses more

[@DataProfessor]

That’s a great concise video summing up the role of a professional data scientist, this video came at the right moment as I transition from academia to industry and totally relate with many of the points mentioned in the video. As mentioned in the later part of the video, I also find the undesirable aspect of data science to be a double-edged sword as on one end the ambiguity may make things unclear but at the same time also leaves room for experimentation and innovation. Papaya Tracker sounds like an interesting personal project!

Miss the times when data science was simply called statistics. Now every company wants a “Data Scientist” that can do: 1. Business management. 2. Presentations. 3. Data fetching and collection. 4. Research. 5. Model building and deployment. 6. Model performance evaluation. 7. Cloud environments. 8. Database administration. 9. Pipeline building and management. 10. Client management. With statistician the responsibilities where quite clear because now every person that works on anything related to data is now a Data Scientist.

[@johnwig285]

Because Data Science aint just abt stats hence the name??? There's the domain knowledge and production aspect, not simply programming everything in R like whats statisticians did back then, now its all abt production and deployment

@@Ashley-uh5lm You don't need to learn advanced maths in advance, but I recommend you to get really comfortable with functions (how their formula translates to their graphical form) and master basic arithmetic to be comfortable with exponents, logarithms, square roots and such things.

[@konstantinradu4399]

Hi Ken can I ask you if it’s true that data analysts are in more demand that data scientists? Idk if eventually I just found a blog which supports more this position rather than data science roles. As I knew Data analysts usually do things less advanced and let data scientists focus on more advanced things, but I suppose it depends on the location involved, on demographics (more or less people as candidates), on the field involved (tech, banks, manufacturers etc) Could you make a video about “supply and demand dynamics on data science vs data analytics/analysis jobs?

[@KenJee_ds]

I will definitely try to work in a video related to this! So the absolute number of data analyst jobs out there is higher than data scientist jobs. So I guess you could say that they are in more demand from a raw numbers perspective. I don't personally know how to quantify the demand on a per company level though. Since the data science salary is still significantly higher than that of a data analyst, it could be that the supply of qualified data scientists is still lower than what the demand calls for in that domain. Don't know if this helped haha, but that is how I would go about thinking about it!
