1
PyTorch, an open-source deep learning framework used to build some of the world's most famous artificial intelligence products.
2
It was created at the Meta AI Research Lab in 2016, but is actually derived from the Lua-based Torch library that dates back to 2002.
3
Fundamentally, it's a library for programming with tensors, which are basically just multi-dimensional arrays that represent data and parameters in deep neural networks.
4
Sounds complicated, but its focus on usability will have you training machine learning models with just a few lines of Python.
5
In addition, it facilitates high-performance parallel computing on a GPU, thanks to NVIDIA's CUDA platform.
6
Developers love prototyping with it because it supports a dynamic computational graph, allowing models to be optimized at runtime.
7
It does this by constructing a directed acyclic graph consisting of functions
8
that keeps track of all the executed operations on the tensors, allowing you to change the shape, size, and operations after every iteration if needed.
9
PyTorch has been used to train models for computer vision AI like Tesla Autopilot, image generators like Stable Diffusion, and speech recognition models like OpenAI Whisper, just to name a few.
10
To get started, install PyTorch, and optionally CUDA, if you want to accelerate computing on your GPU.
11
Now import it into a Python file or notebook.
12
Like I mentioned, a tensor is similar to a multi-dimensional array.
13
Create a 2D array or matrix with Python, then use Torch to convert it into a tensor.
14
Now we can run all kinds of computations on it, like we might convert all these integers into random floating points.
15
We can also perform linear algebra by taking multiple tensors and multiplying them together.
16
What you came here to do though is build a deep neural network, like an image classifier.
17
To handle that, we can define a new class that inherits from the Neural Network Module class.
18
Inside the constructor, we can build it out layer by layer.
19
The flattened layer will take a multi-dimensional input, like an image, and convert it to one dimension.
20
From there, Sequential is used to create a container of layers that the data will flow through.
21
Each layer has multiple nodes, where each node is like its own mini statistical model.
22
As each data point flows through it, it'll try to guess the output, and gradually update a mapping of weights to determine the importance of a given variable.
23
Linear is a fully connected layer that takes the flattened 28x28 image and transforms it to an output of 512.
24
This layer is followed by a non-linear activation function.
25
When activated, it means that feature might be important and outputs the node.
26
Otherwise, it just outputs zero.
27
And finally, we finish with a fully connected layer that outputs the 10 labels the model is trying to predict.
28
With these pieces in place, the next step is to define a forward method that describes the flow of data.
29
And now instantiate the model to a GPU and pass it some input data.
30
This will automatically call its forward method for training and prediction.
31
Congratulations, you just built a neural network.
32
This has been PyTorch in 100 seconds.
33
Thanks for watching, and I will see you in the next one.

Learning English Through Tech: The PyTorch Video Scenario

Imagine watching a short tech video like "PyTorch in 100 Seconds" and using it to boost your English speaking skills. This scenario is perfect for IELTS speaking practice or everyday fluency—you’ll hear clear, conversational explanations of complex ideas, which trains you to follow fast, natural speech while learning new vocabulary. The video’s mix of technical terms and simple explanations makes it ideal for practicing pronunciation, intonation, and pacing.

Useful Chunks & Collocations to Memorize

  • "open-source deep learning framework" – A common phrase in tech, great for discussing tools.
  • "facilitates high-performance parallel computing" – Learn how to describe technical benefits smoothly.
  • "dynamic computational graph" – A key term, but the structure shows how to link adjectives and nouns.
  • "train models for computer vision AI" – Useful for talking about AI applications.
  • "define a new class that inherits from" – Perfect for explaining programming concepts clearly.
  • "gradually update a mapping of weights" – Shows how to describe incremental processes.

Your Shadowing Challenge: Try It Now

Shadowing is a proven way to improve speaking—here’s your task. Find the "PyTorch in 100 Seconds" video and play a 10-second clip. Pause, then repeat it immediately, mimicking the speaker’s tone, speed, and stress. Focus on phrases like "tensors, which are basically just multi-dimensional arrays"—notice how the speaker pauses after "tensors" to explain. Do this 5 times with the same clip. For extra practice, use a shadowing app to record yourself and compare. This "shadow speech" method trains your mouth to move like a native and builds listening comprehension. Whether you’re prepping for IELTS or just want better english speaking practice, this exercise works. Ready? Hit play and start shadowing!

Gölgeleme Tekniği Nedir?

Gölgeleme, başlangıçta profesyonel tercüman eğitimi için geliştirilen ve çok dilli Dr. Alexander Arguelles tarafından popüler hale getirilen, bilim destekli bir dil öğrenme tekniğidir. Yöntem basit ama güçlüdür: ana dili İngilizce olan bir sesi dinler ve hemen yüksek sesle tekrar edersiniz — konuşmacıyı 1-2 saniye gecikmeyle takip eden bir gölge gibi. Pasif dinleme veya dilbilgisi alıştırmalarının aksine, gölgeleme beyninizi ve ağız kaslarınızı gerçek konuşma kalıplarını eşzamanlı olarak işlemeye ve yeniden üretmeye zorlar. Araştırmalar, telaffuz doğruluğu, tonlama, ritim, bağlı konuşma, dinleme anlama ve konuşma akıcılığını önemli ölçüde geliştirdiğini göstermektedir — bu da onu IELTS Konuşma hazırlığı ve gerçek dünya İngilizce iletişimi için en etkili yöntemlerden biri yapar.
