After hours of searching on google on the above mentioned topic. I am unable to contrast the difference between model based testing and model driven testing. Tons of definitions are there,. But there is no clear definition with real world example.
Can anyone please help me understand the difference between these two with the help of real world example.
I'm afraid there is no clear-cut difference between the two. First, because everybody uses a different terminology (there is no "standard" definition for these terms). Secondly, because IMO, both terms refer to the same concept (using models as part of the process of writing the tests for your system) and only differ regarding the importance of the role of models in the testing process.
To me, model-driven implies a stronger role of the models (i.e. models are used to derive the tests) than model-based (where models are used but maybe as an additional input in the test generation process).
At least, this is how I explain other "model-based" vs "model-driven" concepts as I tried to explain in more detail here: http://modeling-languages.com/clarifying-concepts-mbe-vs-mde-vs-mdd-vs-mda/

I've been a full stack web developer for 15 years now and would like to be involved in machine learning. There is already a specific scenario for this: We have a database with several million products and one product image each. There is also a database with about 5000 terms.
A product image is linked to several terms (usually 3 - 20), whereby the link still has a weighting (1-100%). The terms are always of a visual nature, that is, they describe a visually recognizable feature on the image.
The aim should now be to upload a new image (of course with thematic reference) and to get an answer with possible terms (including probability) based on the already classified images.
Do you have any advice on how best to start here? Is there a framework that comes close to this scenario? Is TensorFlow relevant for this task? What new language should I learn?
Thank you very much!
TensorFlow can be used, it's pretty "low-level" though. So if you're just starting out you might be better off using Keras with a TensorFlow backend as it's more userfriendly.
Regarding languages you will probably use Python. So if you don't know it already you should get started. In my opinion you can also learn it on-the-fly while practicing as you're already a developer.
As for tutorials you will have to probably pick out the relevant bits of many different tutorials. You could get started with something like this:

I have a large legacy .NET application that has evolved and grown over the years to include many components and moving parts. I want to develop a strategy for developing automated unit and integration tests for this application and to that end I think a graphical representation would be key.
What I am picturing is some sort of diagram I could use to guide the process of writing up the test cases, help achieve better coverage, and eventually refer back to once a specific test fails. Does anyone have any thoughts on what type of diagram could fulfill this goal? My guess is this would be a variant of the classic functional block diagram, but I have not found examples that specifically relate to the design of an automated testing strategy.
Could this be what you are looking for?
The UTP provides extensions to UML to
support the design, visualization,
specification, analysis, construction,
and documentation of the artifacts
involved in testing. It is
independent of implementation
languages and technologies, and can be
applied in a variety of domains of
development.

I have been asked to create a traceability matrix that maps between the Requirements and Design document. I am having a lot of trouble working out how I link a single requirement to the design as the link is nearly always 1:M and is therefore difficult to map and maintain. Can any point be in the direction of any examples, or provide some advice on how you manage the matrix in this context. Requirements to Testing makes sense to me, however I fail to see why I need Requirements to Design, apparently this is required for our CMMI3 audit.
Thanks for the help
It appears to me like you are talking about the role of a requirements analyst. There are various tools to help in this process, the leading commercial contender is IBM Doors. Although I believe this can equally well be acheieved using a wiki and hyperlinks within wiki pages to denote dependancy and linkage.
If you have a Requirements Spec and a Design and they aren't already linked in some way then your boss has missed the point of Requirements Management in the first place.
Requirements should guide the design process and be linked from the beginning not merely linked afterwards to keep an auditor happy. Anything you design should be done in a particular way to meet a requirement.
To cut a long story short... Personally, I would stick both the Requirements and the design in a wiki and link them together as I mentioned above. You're basically being asked to make the documentation for a process that either didn't occur or wasn't written down.
The compliance matrix is a two-dimensional table that contains the correspondence of the functional requirements of the product and the prepared test cases. In the headings of the columns of the table there are requirements, and in the header lines - test scenarios. At the intersection is a mark, meaning that the requirement of the current column is covered by the test script of the current line.
The compliance matrix is used by QA engineers to validate product coverage with tests. The TM is an integral part of the test plan.

How to write a vision [generally] for some business ? Is it have some template ? any example ?
Business about online ticket services .
What is a 'vision'?
It's such a nebulous objective... I don't see how there could be a template. Unlike requirements specifications, functional specifications etc, there is no accepted understanding of what a 'vision' actually is...
I'd speak to the person who commissioned you to write the 'vision', and ask them what exactly they are trying to achieve and what their expectations are.
Here is a nice article on the Vision. Note that it doesn't have to be a heavyweight document (spend as little time as possible but as much as required). For more formal templates, RUP has some for the Vision artifact.
Karl Wiegers' book, Software Requirements, has an excellent template. I've used in for several projects. It seems a bit formulaic at first, but over the subsequent days and months, really helps a team keep focus.

The Business Motivation Model is a great source. They define what a business vision is, relate this concept to other relevant concepts in the organisation, and give good examples.
If you are interested in how business requirements are refined into user requirements and how, eventually, they determine what a software system does, you may want to have a look at the OPEN/Metis white paper.
First i warn you : Do not be a template zombie...
Secondly to give you just an idea OpenUP has a nice -non commercial Vision Template...
Check my answer how you can get it : RUP (Rational Unified Process)

After reading the definition of procedural design (http://en.wikipedia.org/wiki/Design_document) and searching for a few example diagrams, I have been having trouble on finding out more on what procedural design means other than finding this diagram (http://www.kelso.scotborders.sch.uk/departments/computing/resources/mindmaps/Procedural%20program%20design.gif). Typically, when is this type of documentation necessary? Is it when there's a specific algorithm used in the application?
This is most often used when you have a few very similar constructs that are used really often. In a way SQL is a "procedural design" since it limits you to tables and column and a handful of operations which can be applied to the "data model" (= the database).
Code generators thrive in this area since they have a large but simple input and generate a lot of code that would be extremely tedious and error prone to write by hand. In a similar way, you can generate "documentation" for this which is usually a big waste of time since it will be enormous in volume and contain very little information about how the system works.
[EDIT] In computer science the amount of information in a message is the amount of "surprise" you get per bit. So one page of "1'000 feet view" which is tight packed with information, which gives you a compressed introduction how the system is designed and how you can find your way around, is worth more than 1'000 pages of documentation generated from a data model.
