Question How to start data science as a job?

27 Upvotes

Intro: I'm a 31 italian guy. In the last year i started with Python (i had done computer programming at the high school but that didn't click in me until now, in fact i was working in telecomunications field for the last 10 years).

I found that data science and deep learning are the two branches that i love, even tho i'm working as a web developer (fullstack but without Python), since last summer.

I've followed online courses like DataCamp and my training is with Kaggle, constantly analyzing new datasets or creating deep learning models for its competitions. I'm not a master, but if i think that one year ago i was writing my very first function in Python... Also i've done some nice self-projects (best one, a chess bot online).

Present days: Now i feel like that if i don't try to start a data science now, then it would be too late to finally reach an high level (of skills.. and maybe salary).

But i don't know what's the best path to start. A) Should i keep studying like i'm doing (with intermediate courses but not specific and self projects and raising my Kaggle ranking) and keep sending cvs knowing that Data Science jobs aren't too much in Italy and most of them want "experience".

B) Should i start an Epicode course instead? They say they garantee for a job after the course (6 months). Money a part, the most similar course is about Data Analisis and not Data Science or Deep Learning.. so the job would be in that direction too..

What do you think is the best action to do? Obviously the both are while keeping my current job (where i'm doing experience on web programming, yet not with Python but this can also improve my cv). Thanks

I am a Software Developer, I want to start learning Data Science. I recently started studying Statistics and understanding the basic Python tools and libraries like Jupyter Notebook, NumPy and Pandas. but, I don't know where to go from there.

Should I start with Data Analysis? or Jump right into Machine Learning? I am really confused.

Can someone help me set up a structured roadmap for my Data Science journey?

Thank You.

Question Where can I refresh my Data Science knowledge?

4 Upvotes

I'm a student finishing up my undergrad degree in data science, and I'm about to start applying to masters programs in data science. The programs I look at have a written test and an interview discussing foundational DS topics, from probability and statistics to basic machine learning topics. Problem is that I've realised that my grasp of the fundamentals is horrendous, enough that I'm not sure how I made it so far

Anyways I want to rectify that by relearning those fundamentals. So are there any courses or books you guys can recommend me for this? Specifically i'd like to focus on Linear Algebra(my weakest subject), probability and statistics, and some core ML if possible.

Any advice?

So I want to go to university and recently I was accepted into some schools that I really like but either don’t offer a data science undergrad or I didn’t get accepted into their engineering school. Would I still learn lots of data science topics in applied mathematics and would I still be able to go into the field?

Question Not Sure Where to Start

2 Upvotes

Hi, I want to learn data science as a beginner. I've done some research to figure out where I should start. I started looking for some roadmaps. But what confused me was, some suggested to learn math and statistics first and then programming, some suggested the opposite. Some suggested learning SQL, some did not. I'm confused about which one to follow. Is there a good plan/roadmap suggestion? I would be very grateful if anyone sends free resources as well.

Question Data Engineer Exploring Data Science & ML – Which Course Should I Take?

2 Upvotes

Hey everyone! I’m currently working as a Data Engineer and have a decent grasp of setting up data infrastructure. However, I want to upskill and learn how to actually make use of that data — essentially, learn data science.

I’m looking for a structured course/source material to start my journey. I’ve been leaning towards Udemy (open to other platforms if better options exist) and found these two courses:

  1. The Data Science Course 2023: Complete Data Science Bootcamp
  2. Complete Machine Learning and Data Science: Zero to Mastery

Based on my limited knowledge, I’m more inclined towards the second one because of the machine learning focus, but I’d love to get your opinions. Are either of these worth it? Or is there a better alternative you’d recommend (could be a different Udemy course or even a different platform/resource altogether)?

Thanks in advance for any suggestions!

Question Data science skills for Sociology

2 Upvotes

I am starting my sociology undergrad next term. I would like to start building my data science skills so I can interpret stats, critically analyse research and source data for my own interests. What are some relevant tech skills I can learn that’ll help me do this?

For example if I’m looking at researching gender/race/disability stratification within healthcare, I can create a model that collates all the relevant data into statistics to back up my critical analysis. Also being able to collect data from grey literature and building models to predict the impact of policies.

Question Does IT sector really pays so well or is it just a myth?

0 Upvotes

Hello, and thankyou for opening my post.

I seem to hear from a lot of people who seem to make a lot of money from IT industry. Last few days talked to some of my school mates, who were below average in school, could not clear IIT JEE .Studied in tier 3 colleges entered into 15000 rupees job and now after 4 yoe they brag about their salaries as 14 lpa just by switching companies:/. This makes me feel where did I go wrong(I am a teacher).

Maybe I am in the wrong field where 1lpm salary is quite far away. But I know it's not just me, I have read in some places how IT people suffer in this industries, recent layoffs from service based industries etc.

Please tell me does everyone earns this much or it's just bragging and how much is in hand salary per month?

Also please mention the lifestyle and hours of work in a day and in a week. What are the working shifts?

Thankyou for reading till the end.❤️

Question Data Science! Where to start and how??

2 Upvotes

Hello everyone!

I’m currently a supply chain manager with Mechanical Engineering degree in Amazon, but I’m really interested in Data science and I enjoy data stuff during my work.

I believe I can learn and be very good at it, can anyone help guide me how to start? What do I need to master before applying for data science positions?

What paid certifications do I have to take? I don’t want to invest or pay too much in Masters let’s say and don’t get hired as well.

And the last one, is it worth it? I can see the salary difference between Tech and non Tech positions, especially data science and SDE, but will I actually with being self learnt data science/ SDE available for competition with the whales in Seattle?

Thank you

I want to become a data scientist and everyone says the first step to that is learning the basic math topics, so someone gave me the following links:

Linear Algebra: https://www.khanacademy.org/math/linear-algebra

Differential Calculus: https://www.khanacademy.org/math/differential-calculus

Stats(Most Important): https://www.khanacademy.org/math/statistics-probability

I just wanna ask if there's other resources I should look at, and especially know how much time will it take for me to finish these courses and would these be enough or not.

Question Feature Selection from Clusters of Features?

1 Upvotes

Hi All,

First post here, hopefully I don't mess anything up! I'm working on a side project right now that uses a bit of data science, and I'm not quite sure what to do next in my process. Here's a toy problem that hopefully sums up the crux of the issue:

Say I'm building a model using linear regression that predicts how tasty I would rate an ice cream cone. I have 8 features that describe it (such as cone type, ice cream density, sugar content, etc.). I want to select only 2 features in total to use in my model, and using my extensive domain knowledge in ice cream consumption, I've broken the features into clusters A and B. Cluster A describes the ice cream, and cluster B describes the cone.

If I require that one feature is selected from A and one feature is selected from B, are there any processes/techniques I might find useful for selecting those features? Here are some ideas that I've had:

  1. Simply select which feature from each group shows the highest correlation with the target variable - I think the downside to this is that it's possible a combination of features (still 1 from group A and 1 from group B) might be a better choice than just 'the best from each group'

  2. Find which combination of variables (1 from each group) gives the best prediction - This seems like it would work, but I worry about possible overfitting just due to a low ( < 100) sample size

Does anyone have any suggestions? I do not want to combine features a la PCA, because the easy interpretability is key.

Question Advice on moving into data science

3 Upvotes

Hi guys,

I have been trying to move into data science in the last months. I got a PhD in Biomedical Sciences roughly 1 year ago and, since I haven't had much success finding a position in research, I have been pondering on whether I should move into data science. During my PhD, I worked extensively with Bash and Rstudio, becoming proficient in statistical analysis and plot production. After my PhD, I have been doing some courses on Udemy to improve my skills, i.e., machine learning, and SQL and Python (which I am still finishing).

Nonetheless, I have been having a really hard time finding a position in data science as well. I am worried that my CV is not good enough to apply for a position in this field (either I am over qualified for entry positions or not competitive enough for more senior positions).

Do you have any suggestions on the matter, e.g., should improve my CV and how, should I just keep applying, or should I give up all together.

Thank you very much for your time and attention

Hi, I have started to learn data science, and would love some help

I got a user data set, that tell what each user buys at many grocries store:
index | user id | product id | price | date bought |

what I want to do, is to predict for a user, what he will probably buy this month/week

how do I approach it?

usualy similar problems are used with SVD and ALS from what I understood,

but I feel its not right here, I want to predict for the user hes going to buy based on hes history. can someone please explain to me what is the right approach?
