A New Markup-based Typesetting System That Is Powerful & Easy to Learn

Typst is a new markup-based typsetting system that is designed to be as powerful as LaTeX while being much easier to learn and use. Typst has:

Built-in markup for the most common formatting tasks
Flexible functions for everything else
A tightly integrated scripting system
Math typesetting, bibliography management, and more
Fast compile times thanks to incremental compilation
Friendly error messages in case something goes wrong

This repository contains the Typst compiler and its CLI, which is everything you need to compile Typst documents locally. For the best writing experience, consider signing up to our collaborative online editor for free. It is currently in public beta.

Example

A gentle introduction to Typst is available in our documentation. However, if you want to see the power of Typst encapsulated in one image, here it is:

Example

Let's dissect what's going on:

We use set rules to configure element properties like the size of pages or the numbering of headings. By setting the page height to auto, it scales to fit the content. Set rules accommodate the most common configurations. If you need full control, you can also use show rules to completely redefine the appearance of an element.

We insert a heading with the = Heading syntax. One equals sign creates a top level heading, two create a subheading and so on. Typst has more lightweight markup like this, see the syntax reference for a full list.

Mathematical equations are enclosed in dollar signs. By adding extra spaces around the contents of a equation, we can put it into a separate block. Multi-letter identifiers are interpreted as Typst definitions and functions unless put into quotes. This way, we don't need backslashes for things like floor and sqrt. And phi.alt applies the alt modifier to the phi to select a particular symbol variant.

Now, we get to some scripting. To input code into a Typst document, we can write a hashtag followed by an expression. We define two variables and a recursive function to compute the n-th fibonacci number. Then, we display the results in a center-aligned table. The table function takes its cells row-by-row. Therefore, we first pass the formulas $F_1$ to $F_10$ and then the computed fibonacci numbers. We apply the spreading operator (..) to both because they are arrays and we want to pass the arrays' items as individual arguments.

Text version of the code example.

#set page(width: 10cm, height: auto)
#set heading(numbering: "1.")

= Fibonacci sequence
The Fibonacci sequence is defined through the
_recurrence relation_ $F_n = F_(n-1) + F_(n-2)$.
It can also be expressed in closed form:

$ F_n = floor(1 / sqrt(5) phi.alt^n), quad
  phi.alt = (1 + sqrt(5)) / 2 $

#let count = 10
#let nums = range(1, count + 1)
#let fib(n) = (
  if n <= 2 { 1 }
  else { fib(n - 1) + fib(n - 2) }
)

The first #count numbers of the sequence are:

#align(center, table(
  columns: count,
  ..nums.map(n => $F_#n$),
  ..nums.map(n => str(fib(n))),
))

Install and use

You can get sources and pre-built binaries for the latest release of Typst from the releases page. This will give you Typst's CLI which converts Typst sources into PDFs.

# Creates `file.pdf` in working directory.
typst file.typ

# Creates PDF file at the desired path.
typst path/to/source.typ path/to/output.pdf

You can also watch source files and automatically recompile on changes. This is faster than compiling from scratch each time because Typst has incremental compilation.

# Watches source files and recompiles on changes.
typst --watch file.typ

If you prefer an integrated IDE-like experience with autocompletion and instant preview, you can also check out the Typst web app, which is currently in public beta.

Build from source

To build Typst yourself, you need to have the latest stable Rust installed. Then, you can build the CLI with the following command:

cargo build -p typst-cli --release

The optimized binary will be stored in target/release/.

Contributing

We would love to see contributions from the community. If you experience bugs, feel free to open an issue or send a PR with a fix. For new features, we would invite you to open an issue first so we can explore the design space together. If you want to contribute and are wondering how everything works, also check out the ARCHITECTURE.md file. It explains how the compiler works.

Design Principles

All of Typst has been designed with three key goals in mind: Power, simplicity, and performance. We think it's time for a system that matches the power of LaTeX, is easy to learn and use, all while being fast enough to realize instant preview. To achieve these goals, we follow three core design principles:

Simplicity through Consistency: If you know how to do one thing in Typst, you should be able to transfer that knowledge to other things. If there are multiple ways to do the same thing, one of them should be at a different level of abstraction than the other. E.g. it's okay that = Introduction and #heading[Introduction] do the same thing because the former is just syntax sugar for the latter.

Power through Composability: There are two ways to make something flexible: Have a knob for everything or have a few knobs that you can combine in many ways. Typst is designed with the second way in mind. We provide systems that you can compose in ways we've never even thought of. TeX is also in the second category, but it's a bit low-level and therefore people use LaTeX instead. But there, we don't really have that much composability. Instead, there's a package for everything (\usepackage{knob}).

Performance through Incrementality: All Typst language features must accommodate for incremental compilation. Luckily we have comemo, a system for incremental compilation which does most of the hard work in the background.

Reinforcement Learning Based Recommender Systems

Develop personalized apps using a combination of Reinforcement Learning and NLP/Chatbots

**Abstract. **We present a Reinforcement Learning (RL) based approach to implement Recommender Systems. The results are based on a real-life Wellness app that is able to provide personalized health / activity related content to users in an interactive fashion. Unfortunately, current recommender systems are unable to adapt to continuously evolving features, e.g. user sentiment, and scenarios where the RL reward needs to computed based on multiple and unreliable feedback channels (e.g., sensors, wearables). To overcome this, we propose three constructs: (i) weighted feedback channels, (ii) delayed rewards, and (iii) reward boosting, which we believe are essential for RL to be used in Recommender Systems.

This paper appears in the proceedings of AAI4H — Advances in Artificial Intelligence for Healthcare Workshop, co-located with the 24th European Conference on Artificial Intelligence (ECAI 2020), Sep 2020 (paper pdf) (ppt)

1 Introduction

Health / Wellness apps have historically suffered from low adoption rates. Personalized recommendations have the potential of improving adoption, by making increasingly relevant and timely recommendations to users. While recommendation engines (and consequently, the apps based on them) have grown in maturity, they still suffer from the ‘cold start’ problem and the fact that it is basically a push-based mechanism lacking the level of interactivity needed to make such apps appealing to millennials.

We present a Wellness app case-study where we applied a combination of Reinforcement Learning (RL) and Natural Language Processing (NLP) / Chatbots to provide a highly personalized and interactive experience to users. We focus on the interactive aspect of the app, where the app is able to profile and converse with users in real-time, providing relevant content adapted to the current sentiment and past preferences of the user.

The core of such chatbots is an intent recognition Natural Language Understanding (NLU) engine, which is trained with hard-coded examples of question variations. When no intent is matched with a confidence level above 30%, the chatbot returns a fallback answer. The user sentiment is computed based on both the (explicit) user response and (implicit) environmental aspects, e.g. location (home, office, market, …), temperature, lighting, time of the day, weather, other family members present in the vicinity, and so on; to further adapt the chatbot response.

RL refers to a branch of Artificial Intelligence (AI), which is able to achieve complex goals by maximizing a reward function in real-time. The reward function works similar to incentivizing a child with candy and spankings, such that the algorithm is penalized when it takes a wrong decision and rewarded when it takes a right one — this is reinforcement. The reinforcement aspect also allows it to adapt faster to real-time changes in the user sentiment. For a detailed introduction to RL frameworks, the interested reader is referred to [1].

Previous works have explored RL in the context of Recommender Systems [2, 3, 4, 5], and enterprise adoption also seems to be gaining momentum with the recent availability of Cloud APIs (e.g. Azure Personalizer [6, 7]) and Google’s RecSim [8]. However, they still work like a typical Recommender System. Given a user profile and categorized recommendations, the system makes a recommendation based on popularity, interests, demographics, frequency and other features. The main novelty of these systems is that they are able to identify the features (or combination of features) of recommendations getting higher rewards for a specific user; which can then be customized for that user to provide better recommendations [9].

Unfortunately, this is still inefficient for real-life systems which need to adapt to continuously evolving features, e.g. user sentiment, and where the reward needs to computed based on multiple and unreliable feedback channels (e.g., sensors, wearables).

The rest of the paper is organized as follows: Section 2 outlines the problem scenario and formulates it as an RL problem. In Section 3, we propose

three RL constructs needed to overcome the above limitations: (i) weighted feedback channels, (ii) delayed rewards, and (iii) reward boosting, which we believe are essential constructs for RL to be used in Recommender Systems.

‘Delayed Rewards’ in this context is different from the notion of Delayed RL [10], where rewards in the distant future are not considered as valuable as immediate rewards. This is very different from our notion of ‘Delayed Rewards’ where a received reward is only applied after its consistency has been validated by a subsequent action. Section 4 concludes the paper and provides directions for future research.
