First Principle Thinking: Building Structured Systems in Life
First Principle Thinking is a powerful tool that enables us to examine and challenge all assumptions related to a topic, leading to a deeper and more comprehensive understanding of it. By questioning and challenging common understanding, we can uncover hidden assumptions and biases that may have been previously overlooked. FPT is one of my mental […] Continue reading

Announcement 📢 Releasing dlpackrs
DLPack is the standard in-memory data format that facilitates zero-cost tensor transfer across major Deep Learning frameworks (PyTorch, TensorFlow and TVM) and the supported Python Array processing frameworks such as Numpy, CuPy. The dlpackrs provides a safe idiomatic Rust binding where Rust ndarray and tensor frameworks can use it to gain the same kind of […] Continue reading

Announcement 📢 Releasing smartalloc
If you happen to write unsafe code in Rust where normal static checks are not available and want better UX for detecting memory issues along side using various sanitizers, checkout my new crate smartalloc which provides idiomatic Rust binding for the original C version here. Beside the reason in README, note that MIRI can’t be […] Continue reading

Announcement 📢 Create your own programming language with Rust
After almost a year from my last blog post, in this short post I’m very happy to announce that I’m writing a free online book where early chapters are available now. I’ve explained my motivations and goals in the introduction. The accompanying codes are also available on my GitHub. Feedbacks are welcome and happy learning. […] Continue reading

Rust std study series: Pin
This time we dive into std::pin which has a dense documentation. Types that pin data to its location in memory. It is sometimes useful to have objects that are guaranteed to not move, in the sense that their placement in memory does not change, and can thus be relied upon. A prime example of such […] Continue reading

Rust std study series: alloc
Let’s get deep into std::alloc! Memory allocator 101 The very basic need for any program to compile and execute is having access to either physical memory or virtual memory. An allocator is responsible for providing such an access. You can think of an allocator as a service, taking some sort of requests and either giving […] Continue reading

Rust std study series: Interior mutability
Continuing the standard library study, it’s time for Cell<T>! Rust compiler enforces multiple reads access and a single write access mutually exclusive, i.e. either multiple shared references & or one and only one mutable reference & mut. So essentially, Rust prevents the evil of aliasing and mutation between multiple threads. Cell<T> is a sharable mutable […] Continue reading

The State of Machine Learning in Rust
Every once in a while this topic comes up on a social media or Rust user channel. I’d like to describe briefly the way I see where things are going by a little bit of history as well as some information about existing flux of Machine Learning/Deep Learning frameworks and major recent trends. Brief history […] Continue reading

Rust std study series: VecDeque
Continuing from Rust standard library study series, it’s time for VecDeque<T>. Because of its similarity to Vec, there isn’t much to say. A double-ended queue implemented with a growable ring buffer. The “default” usage of this type as a queue is to use push_back to add to the queue, and pop_front to remove from the […] Continue reading

Rust std study series: LinkedList
Continuing from Rust standard library study series, it’s time for LinkedList<T>. Note that implementation are taken from Rust stable v1.33.0. A doubly-linked list with owned nodes. The LinkedList allows pushing and popping elements at either end in constant time. Almost always it is better to use Vec or VecDeque instead of LinkedList. In general, array-based […] Continue reading

Variance in Rust: An intuitive explanation
Recently I’ve made a presentation about subtyping and variance in Rust for our local Vancouver Rust meetup, but I still think intuition was rather lost in the formalism, so here’s my shot at explaining it as intuitively as I can. For more succinct definitions, please checkout the presentation or the resources at the end. First, […] Continue reading

Rust std study series: Vec
The upcoming series of blog posts will contain my study of Rust standard library. I’ve partially written some parts of the series in scattered places and want to gather them in one place for better and easier access. I intend to update whenever I discover something interesting/important to remember. I’m referring to implementations in Rust […] Continue reading

What’s up with word embedding?
Word embedding is one of the interesting areas of research in Natural Language Processing. There are huge amount of materials with a lot of interesting ideas. I have been studying some of them lately and in this post, I’d like to create a brief account of the ideas I have found most interesting so far. […] Continue reading

General Monty Hall Simulation
The idea of this post came up to my mind last night. I’m assuming you have already heard about the famous Monty Hall Problem (if you haven’t, watch the quicker intro in Numberphile clip). Here I’d like to demonstrate a simulation taking the general case into account, i.e. assume we have bins (boxes or doors, whatever) and […] Continue reading

Restaurant Revenue Prediction with BART Machine
In this post, I’d like to show you how to use the newly written package on Bayesian Additive Regression Trees i.e. BART Machine for Restaurant Revenue Prediction with R. The datasets are part of the passed Kaggle competition that can be found here. What is BART? BART is the Bayesian sibling of Random Forest. For […] Continue reading

Vector Bundles, Locally Free Sheaves and Divisors on a Curve
In this post, I’ll be summarizing the basics of the correspondence between vector bundles, locally free sheaves and divisors on a smooth curve (defined over an algebraically closed field of characteristic zero) together with some of their individual properties. Locally free sheaves and Vector bundles: Proposition 1: a) A coherent sheaf on a curve is locally free […] Continue reading

Classification of Vector Bundles on Elliptic curves
I’m supposed to give a talk on this subject for one of my courses, so I consider this post as a “pre-exposition.” I learned from and heavily used the great exposition “Vector bundles on curves” by Montserrat Teixidor I Bigas in this post. I wrote up the pre-requisites here. In 1957, Atiyah in this famous paper “Vector bundles over […] Continue reading

Some Homological Algebra Computations
In this post, I’m going to write down the detailed proofs of some of the exercises in Rotman’s Homological Algebra. They were asked in ML and then answered by me. 1. Let be a torsion abelian group. Then , where is the unit circle. One point is that the structure of the circle group is […] Continue reading
About Me
I am a Machine Learning since 2013, transforming complex data into manageable solutions. Previously grounded in the discipline of pure Mathematics, I transitioned from beauty of Math to innovative code. I blog to manage and structure information.
