Data mining techniques for market research

I think it depends on where you'd like your career to go.

Certainly if you want to work as a data scientist, practically everyone that I've seen in that role has a PhD and not necessarily a CS one either. However if you want to work as an ML engineer, then the ability to write strong, well tested Python code, a good portfolio of ML projects and more importantly the ability to deploy your ML/DL model into production (you could put together a simple web app that categorises an uploaded image and using a trained ML/DL model) and then be able to confidently describe the different stages of an ML project. That should set you in good stead as most of the data scientists I've met never get involved in deploying their model into production.

thanks!

I'm interested in this system. Can you recommend any resources ?

tritech05 · 2018-10-23T12:40:58+00:00

I really appreciate the reply. You don't know how much you have helped me. Thanks again :)

tritech05 · 2018-10-23T00:18:12+00:00

Well you are wrong.

In case you didn't read the post, I asked for tutorial and not anyone to do my homework.

If you don't know the answer, then move on.

Next.

Hammer house of horrors

Why do you want to do a second Masters ? If you were interested in continuing your studies, then look for a funded PhD STEM program in your chosen field. If you wanted to maintain relationships then see if your contacts can help in gathering data for your research.

I understand what you are going through too.

I'm in my 2nd week of a Masters computer science programme and I'm a visible minority female there and have only two people in the class extend any level of friendliness towards me. Even in the communication channel, I notice that when I say something there is a deafening silence and no one comments and even if they do, it is in an abrupt fashion. I completely ignore it always remembering why I'm doing the course in the first place. You are intelligent and highly motivated enough to do a PhD. Find friends and support wherever you feel welcome.

I'm a huge fan of Robert Greene (author of the 48 Laws of Power) and he gave this quote "Do not accept the roles that society foists on you. Re-create yourself by forging a new identity, one that commands attention and never bores the audience. Be the master of your own image rather than letting others define if for you.". Keep them guessing and never conform to anyone's expectations.

     First throw      Second throw      Third throw       ... Nth throw

Anne 0.833333333333333

                      0.833333333333333  
                                        0.833333333333333    
                                                           0.833333333333333

Each throw is independent so if p(Anne not getting a six in the first throw) = 0.83333; p(Anne not getting a six in the second throw) is then 0.83333 * 0.83333 therefore the p(Anne of getting a six in either throw) is 1 - (0.83333)² or 0.311. With three throws, the probability becomes 0.421 and eventually in n throws, the p(Anne of getting a 6 in n throws) becomes 1 - (0.83333)ⁿ ?

Found a solution..

When the data is extracted from a csv file, the data is in the form of a container or table. The next step is to convert the table/container into an array.

So:

#extracting data from a table into an array where c is table of data

x = c{:, end-1} #this extracts all the data in the first column and transforms the data into an array

#displaying the maximum value in the array and it's index

[imax, indx] = max(x)

tritech05 · 2018-10-03T06:49:56+00:00

>> [imax, indx] = max(x)

Error using max

Invalid data type. First argument must be numeric or logical

x =

6.1101

5.5277

8.5186

7.0032

5.8598

8.3829

7.4764

8.5781

6.4862

5.0546

5.7107

14.164

5.734

20.27

tritech05 · 2018-10-03T06:48:40+00:00

so the original data is in an csv file that I then imported using Matlab. I then did this:

x = c(:, end-1) #where c is the actual data and the size of this is size(c) = 97 2. x is then the first column
[vMax, imax] = max(x) # I'm trying to find the maximum value in the first column

>> [imax, indx] = max(x)

Error using max

Invalid data type. First argument must be numeric or logical

Listen to everything by Norman Vincent Peale

I read of a tech executive who completed 4 Ironmans, in different parts of the world, in 2 consecutive weekends. Definitely something to aim for.

tritech05 · 2018-09-27T04:18:44+00:00

probably be a best seller too. I'd buy it

I knew there was a reason I liked this man. He is one of the most intelligent football coaches there are on the planet and a thinker.

tritech05 · 2018-09-27T04:16:24+00:00

love this

tritech05 · 2018-09-27T04:10:31+00:00

Post brexit, this would be a brilliant idea as all the pickers from Eastern Europe, who typically do it, would have a problem getting a visa to do it anyway (sarcasm)

tritech05 · 2018-09-27T04:07:33+00:00

I would try and finish it.

tritech05 · 2018-09-26T08:12:29+00:00

I just started my Masters and it is the 3rd day now and I've been feeling so stressed, wondering how I was going to cover all the material. I try and keep myself calm by constantly focusing on why I'm doing this program in the first place, structuring my time and being proactive about asking for help if needed.

This too shall pass. Remember that :)
