Introduction TL;DR: The Tensor Processing Unit (TPU) is a specialized hardware chip developed by Google to accelerate the training and inference of its AI models. Unlike general-purpose CPUs and GPUs, the TPU is an Application-Specific Integrated Circuit (ASIC), highly optimized for the ‘matrix multiplication’ operations central to artificial intelligence. It utilizes a powerful systolic array architecture, enabling massive parallel processing of data to power services like Google Search and Gemini, and is available to external users via the Cloud TPU service on Google Cloud Platform (GCP). Tensor Processing Unit (TPU) is a custom-developed AI accelerator designed by Google specifically for machine learning and deep learning workloads. The core function of AI models, particularly neural networks, involves immense amounts of tensor operations, which are essentially multi-dimensional array or matrix multiplications. Traditional Central Processing Units (CPUs) and Graphics Processing Units (GPUs) are designed for a wide range of tasks, but the TPU is a single-purpose processor, or ASIC, built to perform these matrix operations with extreme efficiency. The first-generation TPU was unveiled in May 2016, following its internal deployment since 2015, driven by the escalating computational demands of Google’s AI services. The Core Technology of TPU: The Systolic Array The secret to the TPU’s high performance lies in its specialized architecture, the Systolic Array. For a beginner, this can be visualized as a highly optimized ‘factory conveyor belt’ for calculations. ...

Introduction TL;DR: PyTorch, developed by Meta, is a prominent deep learning framework utilizing a Define-by-Run (Dynamic Computation Graph) approach, which significantly aids intuitive model development and debugging. Its core strength lies in GPU acceleration via Tensor objects and automatic differentiation through Autograd. With the latest stable version being PyTorch 2.9.0 (as of October 2025), PyTorch continues to evolve its ecosystem, offering robust tools like TorchScript and ONNX for production deployment, making it a powerful, Python-centric platform for both research and industry applications. PyTorch is an open-source machine learning library designed to accelerate the path from research prototyping to production deployment. This article explores the core architectural features that make PyTorch a preferred choice for many developers and outlines its practical application in real-world environments. Core Architecture and Flexibility 1. Tensors and GPU Acceleration In PyTorch, a Tensor is the fundamental data structure, analogous to NumPy arrays but with crucial support for GPU (Graphics Processing Unit) acceleration. This capability is essential for handling the massive computational loads of modern deep learning models. By simply moving a Tensor to a CUDA device, complex matrix operations are parallelized, drastically reducing model training time. ...

Introduction TL;DR: Entropy is a core scientific concept defined in two major contexts: Thermodynamics and Information Theory. In thermodynamics, it quantifies the degree of disorder or unusable energy in an isolated system, always increasing according to the Second Law of Thermodynamics. In information theory, specifically Shannon Entropy, it measures the uncertainty of a random variable, acting as the expected value of the information content. Both concepts fundamentally relate to the number of possible states a system can occupy or the uniformity of a probability distribution. The concept of Entropy was first introduced by Rudolf Clausius in the 19th century to describe the direction of energy change in thermodynamic processes. It is a physical quantity representing the thermal state of a system, often popularized as the measure of ‘disorder’ or ‘randomness’. More precisely, it quantifies a system’s tendency towards equilibrium or the degree of reduction in energy available to do useful work. 1. Thermodynamic Entropy and the Second Law Thermodynamic entropy, denoted by $S$, is a fundamental property of a system in thermal physics. Ludwig Boltzmann related entropy to the number of microstates ($\Omega$) a system can attain, reflecting the system’s inherent randomness. ...

Introduction TL;DR: The Joint Embedding Predictive Architecture (JEPA), championed by Meta AI’s Chief AI Scientist Yann LeCun, represents a major architectural alternative to the dominant Large Language Models (LLMs). This analysis explores JEPA’s fundamental principles, its superiority over generative models for building robust World Models, and its latest application in V-JEPA2 as the foundation for future Autonomous AI systems. JEPA is a non-generative architecture designed to construct efficient World Models. It tackles the limitations of LLMs (lack of planning, uncontrollable error growth) by predicting only the abstract representation ($S_y$) of future states, rather than the raw data itself. This allows JEPA to learn the core dynamics and common sense of the world, ignoring uncertain details. With the release of V-JEPA2 in June 2025, Meta AI is leveraging JEPA to learn profound physical world understanding from multimodal sensory data, driving the next phase of AI development toward controllable and safe agents. 1. Defining JEPA: Predicting Abstract Representations JEPA is a core component of LeCun’s prescription for achieving human-level intelligence: learning predictive models of the world through Self-Supervised Learning (SSL). ...

Introduction TL;DR: The Perceptron, invented by Frank Rosenblatt in 1957, is the simplest form of an artificial neural network, performing binary classification by calculating a weighted sum of inputs against a threshold. While the Single-Layer Perceptron could only solve linearly separable problems, its inherent limitation was exposed by the XOR problem in 1969. This led to the development of the Multi-Layer Perceptron (MLP), incorporating hidden layers to solve complex, non-linear classification tasks, serving as the architectural blueprint for modern Deep Learning. This article details the operational principles of the Perceptron, its historical context, and how the evolution to Multi-Layer Perceptrons enabled the advancement of neural network capabilities. 1. The Single-Layer Perceptron’s Operation The Perceptron is fundamentally a supervised learning algorithm for binary classification, modeled after the structure of a biological neuron. It takes multiple binary or real-valued inputs and produces a single binary output (0 or 1). ...
