Entropy coding is the backbone data compression. Novel machine-learning based compression methods often use a new entropy coder called Asymmetric Numeral Systems (ANS) [Duda et al., 2015], which provides very close to optimal bitrates and simplifies [Townsend et al., 2019] advanced compression techniques such as bits-back coding. However, researchers with a background in machine learning often struggle to understand how ANS works, which prevents them from exploiting its full versatility. This paper is meant as an educational resource to make ANS more approachable by presenting it from a new perspective of latent variable models and the so-called bits-back trick. We guide the reader step by step to a complete implementation of ANS in the Python programming language, which we then generalize for more advanced use cases. We also present and empirically evaluate an open-source library of various entropy coders designed for both research and production use. Related teaching videos and problem sets are available online.

A new generation of increasingly autonomous and self-learning systems, which we call embodied systems, is about to be developed. When deploying these systems into a real-life context we face various engineering challenges, as it is crucial to coordinate the behavior of embodied systems in a beneficial manner, ensure their compatibility with our human-centered social values, and design verifiably safe and reliable human-machine interaction. We are arguing that raditional systems engineering is coming to a climacteric from embedded to embodied systems, and with assuring the trustworthiness of dynamic federations of situationally aware, intent-driven, explorative, ever-evolving, largely non-predictable, and increasingly autonomous embodied systems in uncertain, complex, and unpredictable real-world contexts. We are also identifying a number of urgent systems challenges for trustworthy embodied systems, including robust and human-centric AI, cognitive architectures, uncertainty quantification, trustworthy self-integration, and continual analysis and assurance.

This course fully covers from classical C to Modern C style of creating object Oriented Programs from scratch to advance level in a step-by-step approach. The course teaches in detail the latest concepts introduced in C 11, C 14 and C 17. The object oriented programming concepts are covered in detail such that you will learn all the concepts including classes, objects, Data Abstraction, Data Encapsulation, Inheritance, polymorphism (including Operator overloading and Function Overloading). The main focus of the course apart from Fundamentals of programming and Object Oriented Programming is on Templates(including Function and Class Templates), which is a building block to understand STL implementation. The Course entirely covers all String Functions included in the latest version of C along with the basic programming concepts like operators, variables, Conditional statements and looping structures, functions(User-Defined and Recursive Functions), reference parameters, Arrays,File I/O and vectors in C .has been discussed in details.

I've been a teacher at many grade levels, and I own a tutoring center that serves kids from age 4 to 18. I've tutored hundreds of students myself over 10 years. I've spent a lot of time trying to teach concepts, to students, peers, friends, direct reports, you name it. I say this because there is one thing that I beg you to listen to, and it's the number one issue I've seen in students at all levels: We just don't know what we don't know. People aren't great at seeing where their own understanding has small gaps. For any topic, we have a few lines of knowledge that we can spout, but we just aren't aware of the edge cases that exist until we see them. We don't have all the knowledge of how every topic intersects with every related one, and many times, those answers are not easy to figure out. Therein lies why experience is valuable. There is so much about even the basic Data Science topics that we haven't yet come across.

In big tech companies, launching ML models is complex. Every ML model you launch will be interlaced with multiple complex systems. In practice, you will need to understand that there is no free lunch and different ML solutions need to adapt to the complexity of the system in mind. This means, you need fundamental systems design understanding to help you implement a proper ML Ops practice. Understanding systems design and ML Ops best practices will immensely help you reduce technical debt and launch your model scalably.

Artificial intelligence is growing exponentially. There is no doubt about that. Self-driving cars are clocking up millions of miles, IBM Watson is diagnosing patients better than armies of doctors and Google Deepmind's AlphaGo beat the World champion at Go - a game where intuition plays a key role. But the further AI advances, the more complex become the problems it needs to solve. And only Deep Learning can solve such complex problems and that's why it's at the heart of Artificial intelligence.

Data-Free Knowledge Distillation (KD) allows knowledge transfer from a trained neural network (teacher) to a more compact one (student) in the absence of original training data. Existing works use a validation set to monitor the accuracy of the student over real data and report the highest performance throughout the entire process. However, validation data may not be available at distillation time either, making it infeasible to record the student snapshot that achieved the peak accuracy. Therefore, a practical data-free KD method should be robust and ideally provide monotonically increasing student accuracy during distillation. This is challenging because the student experiences knowledge degradation due to the distribution shift of the synthetic data. A straightforward approach to overcome this issue is to store and rehearse the generated samples periodically, which increases the memory footprint and creates privacy concerns. We propose to model the distribution of the previously observed synthetic samples with a generative network. In particular, we design a Variational Autoencoder (VAE) with a training objective that is customized to learn the synthetic data representations optimally. The student is rehearsed by the generative pseudo replay technique, with samples produced by the VAE. Hence knowledge degradation can be prevented without storing any samples. Experiments on image classification benchmarks show that our method optimizes the expected value of the distilled model accuracy while eliminating the large memory overhead incurred by the sample-storing methods.
