TensorFlow Basics: Tensors, Training, Deployment
Key Points
- TensorFlow is an open‑source, multi‑language framework (Python, JavaScript, Java, C++) that lets you develop, train, and improve AI and machine‑learning models.
- A tensor is essentially a multi‑dimensional array (a multilinear algebraic structure) that serves as the fundamental data unit for machine‑learning computations.
- The platform offers an iterative workflow: you can choose training hardware (CPU, GPU, or TPU), access built‑in datasets, and use ready‑made “estimators” or starter neural‑network models to accelerate development.
- TensorFlow provides APIs for model interaction and supports deployment across a wide range of environments, including mobile (iOS/Android), embedded systems (Raspberry Pi, ARM), Linux, and browsers via TensorFlow.js.

On my bucket list for this year is a
commitment to do more tinkering with
machine learning and AI. And as I've
started this research, I keep running
into references to what is a Tensor,
what is a TensorFlow. Let's go ahead and
break these down real quick. TensorFlow
is an open- source project you can
access via GitHub and it can be used
with a variety of modern languages like
Python, JavaScript, Java, and C++. Put
simply, it's used to develop and improve
AI and machine learning models, which is
why you hear about it so much. So, the
second question makes me ask, what is a
tensor anyway? It turns out a tensor is
an algorithm expressed as a multilinear,
which is essentially a complex array
used in machine learning. One way of
showing this is a multi-dimensional
array kind of like this shape.
TensorFlow is an open-source platform
for creating and using models. It's just
that simple. And what I wanted to
outline is kind of the way you work
through it. It is a very iterative
platform where you can really get
started immediately taking advantage of
machine learning. It comes first by
doing the training. Now when it comes to
building these models, creating them,
there are many decisions to make and
this is where TensorFlow really aids you
in this process and you can decide it to
say hey I wanted to train this I have a
set of data uh I want to make this model
be a CPU be trained by CPU or GPU or
there's there's even tensor uh computing
processing units that you can do as well
to train your data but it gives you an
opportunity to make that decision when
you want to create the model. Now, if
you don't have your own data, you can it
will give you data sets that you can
leverage. All right? If you uh kind of
don't want to go the process of creating
your models by hand, there are some
starter let's say we call them
estimators, which are like starter uh
neural networks to get started or models
that you can use to really try to get
jumpstart your your your process of
doing this. And then the last part is
once you have something you have to
deploy that well another great part of
that is you can also give you an API.
Testflow is going to give you an API you
can use code name kas uh but that will
be a way that you can actually input
data to train your models. It
encapsulates any of the models that you
want to create. So very important there
that process of getting started is very
easy. Now the last part you may say is
all right I'm using TensorFlow I want to
know what I want to achieve in my
application but how do I get it into
where I want to develop and that's where
the last part that it offers for you it
gives you a method for deployment a it's
going to let you get into mobile
and embedded abbreviated EM so iOS
Android SDKs
and the ability to get on Raspberry
Pies. All right, Linux, ARM SDKs for you
to get there as well. Secondly, you'll
be able to get
on browsers.
There's going to be a library which is
TensorFlowJS
which will give you a mechanism for
creating and executing your models
inside um your code as well. And also
you can do uh I kind of mentioned
embedded systems, but that's something
you can do. But there's an additional
piece here too. You can get even get in
on embedded devices. They even have
microcontrollers. So the opportunities
are endless here to really get started
here. Well, for me, when I want to get
started with something, I actually love
being able to take advantage of any
platform I can that can help me jump
start and get and get going. And that's
what you should do. I want you to leave
in the comments what you think about
TensorFlow and tell us how easy it was
to get jump start your journey. As
always, see your respon
