Hi, please it is easy doing a masters in data analyst, without any idea, or background information
9 Modules: Semester 1: 1. Machine Learning(bsc) 2.) Data management 3.) Distributed Systems 4.)Multivariate and Cluster Analysis 5.)Data Science Semester 2: 1.) Statistical Learning 2.) Big Data Systems 3.) Data Mining and Analytics 4.) Learning skills through Case studies
Hello, I'm a college student studying yolo model. Can you share the code? I'm so curious about the code content. Thank you for making a wonderful project.

Great videos! Easy to understand, thanks for the explanation.
Thank you, really helpful
Great video, thanks for breaking it down!
Hi, great video! Soon I have to choose a bachelor program keeping in mind that I will probably choose master in data science. I've got 2 options: 1.Mathematics and data analysis 2. Data analysis and engineering (data science) I know that naturally the second option is the better one in terms of a smooth transition. But maybe it is not a huge difference? The first option includes more math oriented topics, the second one - more programming (also in Java for example).I am talking about one of the best uni in my country, the quality of teaching is good when it comes to both options . What would you say and potentially recommend?
I believe it depends right. Both sound great options and will get your foundational layer covered for the most part. Even within option 1, I can assume you will get basic programming such as R (for statistical analysis) or Python. A better question for ya might be: what you do aspire to use this masters degree or what are your future professional goals? Looking to apply these skills in the industry as a data scientist? Do you intend to pursue a PhD in the future? Is research & the higher theoretic field something you’re passionate about? Based on those questions option 1 sounds more theoretical and could help you further down the line. Option 2 sounds more applied and could help you understand how these skills can be applied in a company. The type of industry niche could play a factor too! Thinking of going into manufacturing? I can tell you first hand that our data scientists often work on creating models but often doing a bit of other roles such as data engineering roles and even operations. Perhaps you want to go into big FAANG companies, then maybe those companies have more of a budget to spend solely on r&d and thus option 1 could be helpful. At the end of the day, both could work for anything because if you do option 1 you could work on some side project that involves more programming! On the contrary, if you go for option 2, you could also do self study on very specific math intensive subjects at your own pace while you learn industry ready skill. Hope my very small 2 cents help in some way shape or form! Best of luck!
Very helpful video. Thank you very much. I’m considering completing my studies because of my interest in the academic field and research in data
Would data science be in demand in 2030?
I got a 2.2 in CS (admittedly didn't try hard enough) and been thinking of doing a Masters in Data Science but im not 100% on it. I'll be real and say I'm doing the DS masters to make up for the 2.2, despite being more interested in Data Analytics and rather get a job in that but I have doubts that I can land one with a 2.2 in London(I live in London and I have no previous work experience). How hard would you say a Data Science masters is in general? (I know it depends on the Uni) What would you do if you were in my position? I am genuinely lost at the moment and only have a few days to decide if I want to go forward with the DS Masters 😭
Heey what did you decide on
It’s definitely possible to become a data scientist without a masters and no experience. I did a 9 week data science Bootcamp and I have a degree in Electronic Engineering. I previously worked in construction as a Quantity Surveyor and I got a job as machine learning scientist 3 months after completing the book camp
May I ask which bootcam did you complete?
What other roles would you say a Data Science MSc helps with? I work as a Data Analyst, and want to get an MSc to help advance my career but the job prospects look kind of questionable. Since you graduated, so many great universities also offer Data Science MScs.
Lol i guess the university of Leeds doesn’t really have International students then
About the salary, you provided the averages from Glassdoor and Indeed, but is that what they really are in the market?
Really helpful thanks mate
No problem Jake!
What did you study in your bachelors? I come from a life science background doing my bachelors in that would I find it hard?
I studied maths for my bachelors. A life science background could help, but it really depends on how much stats you know. IMO, the more confident you are with stats, the easier the data science master's will be.
9 modules is insane
It's a lot indeed!
Thanks
Why didn't you apply for any data science graduate roles? they dont ask for much as they are graduate specific
is the salary gross income or net income
It's gross income.
How are you doing brother. Please can I have your email address would love to reach out to you
How are you doing brother Please can I have your email. Would love to read you. Thanks
hi leon i recently got into the university of leeds for computer science master's, i have applied for a few colleges in the US too but my priority is that i get a job after doing my course, so my question is does doing masters with UG increase my chance in getting a job in the uk or does it not matter.
Technically it was in 5 min
Technically 2 minutes if you play at 2x speed.
Hey Can I do Master's in Data Science from UK and do job as a Data Analyst for some experience and than switch to Data Science
Hey leon, how are you? Found your channel on RUclips and it’s been fun.. am so much interested in data science am starting my graduate application pretty soon with an engineering background…but I really need your help with statements of purpose for masters in data science since you are a graduate and have an experience of how it is.… I will be applying to like 10 university in the Uk simply because am an international students.. your reply is highly valued thanks.
How is Aston University for MSc in data analytics?
Basically I'm an international student and I am pursuing my Masters in Data Science course in UK and in my Undergraduate course I don't have work experience other than Internships of about 7-8 months. May I know will I be considered as fresher and also please can you tell me the Interview rounds for jobs in UK after completion of Master degree.
hey there! did you manage to get a job in uk?
"The purpose of this video is not to put you off but to show you the downsides of data science" enjoyed every bit of the video man. I appreciate. I still want to pursue a carrer in data science. I wanted to ask a few questions if you dont mind, how can I reach you?
Thank you very much
Your opinion could mislead people if I'm honest. Black and white logic doesn't help people see the truth easily. Whether R or Python depends on problems you're solving and the team culture.
Thanks for the feedback. I'd add that it also depends on the infrastructure you work with, and since (at least from what I've seen) most companies prefer having a more general infrastructure, Python seems to be the more logical choice for a data science team to use.
HI, is University of Leeds Beckett is good for MSC data Science?
I don't know much about Leeds Beckett University, so I can't really comment on that. Since I'm biased, I'd obviously suggest going to University of Leeds instead but it's really up to you and what you want out of the course.
Hi thanks for the video I'm a btec student and I'm currently trying to apply for data science what's your thoughts on entering in the bachelor's degree
If you're 100% interested in data science, then I say go for it!
How about a data science bachelors degree
I don't know much about data science bachelor's degrees but I'd assume they'd be more practical than something like a pure maths degree.
Hi Leon , would love to see more content coming from you . Please drop in some datascience /ML projects too , Would be more than happy to learn . Thankyou 🌼
Thanks Akansha! I'll try my best :)
Hii brother , thank you for your video, bro I have a question that, I am going to complete my degree in Master's in Data Science from UK this month, can you please suggest me like how to get a job in Data Science field as a International student as Data Science freshers or any advice further please....
No problem! I'd say as a graduate the biggest thing is to make sure you have enough projects on your CV to talk about in the interviews. Try apply to as many companies as possible and really try your best to research each company and their products before beginning the interview process.
Am just a mathematics graduate from university , I want to go into data analytics masters. Will they teach us from scratch, because I have zero background in data science or programming is it possible?
Yes, a data science master's will cover the fundamentals. Since you have a maths background, you can pick more programming or data science theory modules if that's what you want to focus on instead.
Thanks for this, I found it really helpful.
Thanks Stella! Glad you found it helpful :D
i’m an International student and i’m gonna study abroad in uk for data major. Would you suggest me for suitable uni ? Now i’m wavering. Thank you !
That's a really difficult question for me to answer. I'd suggest having a look at reviews for each course and see whether the course content matches with what you want to learn.
i know you mentioned you can get a DS role through experience being a DA, how many years of experience do you think that process would need?
I've seen people go from an analyst to data scientist in 2 or 3 years. but some people take longer. It really depends on what you're exposed to at work. If there's already a bunch of data scientists that you get to work with, then I'd imagine it'd be much quicker to progress.
@@LeonLokk thanks mate for your opinion, not too keen in going back to uni while working as well as the ridiculous fees, I’ll probably play the long game with this 😂
No worries! Going back to uni definitely isn't for everyone, so I get that 🙂
Hey Leon which affordable university in Uk would you recommend me for data science
Of course I'd recommend the University of Leeds because I studied there 😉 but in all seriousness, I can't answer that question and I'd recommend you doing your own research based on your own needs.
is an engineering background problematic when applying for masters in data science
I've seen people with all sorts of different backgrounds, so you're probably fine. Engineering is at least a STEM subject, which will definitely help in data science.
Amazing videos, just wondering if you are able to provide a tutorial on how to use the code?
Thanks Hanson! It's on my list of videos to create, so hopefully I can make a tutorial once I have the chance to sit down and go through the code properly again.
Good morning Leon, I am a foreigner very enthusiastic about doing a master's degree in data science in the UK with the profile you described. For example, I find it very important that the master's degree is based on Python and I am preparing myself to handle this programming language. However, there are too many masters and universities in the UK, which universities do you suggest? I have a bachelor's degree in economics so I am looking to specialise in data science to use big data in the development of public projects. Glasgow University is my first choice for now, what do you think?
It's hard for me to suggest any universities besides my own, as that's the one I studied at. I can only suggest doing your own research on what the course offers and whether it matches with your interests and needs.
how lon lg did it take before you get employed after finishing Ur masters?
It took me around half a year due to COVID lockdowns at the time.
Are you a UK citizen? Most companies need data scientists but just very few of them are willing to sponsor visas.,
Yes I'm British. It really depends on the company but from what I've seen, it's usually the larger international corporations that are more open to sponsorships.
Do They not teach in python. I have no knowledge R language? It is possible without R language?
They didn't really teach Python besides in the machine learning module. They focus mainly on R because of it's popularity in academia.
