How to Build Suno AI: An Engineer's Perspective

Sun, 24 Dec 2023 00:00:00 +0000

Acoustical Society of Japan (ASJ) Student and Young Forum Advent Calendar 2023 Day 24

Suno AI is a generative AI service that automatically produces full songs with vocals simply by providing lyrics, musical style descriptors, and a track title.

Suno AI

While various music generation models have been released recently, Suno AI went especially viral because of its unique lyric-driven interface and the immense entertainment value of generating expressive vocal tracks.

The 100% Guaranteed Diet Method for 2023

Thu, 21 Dec 2023 00:00:00 +0000

Wall Advent Calendar 2023 Day 21

Whether preparing for a wedding, shaking off holiday pounds, or getting ready for summer, we often find ourselves wanting to lose around 3 kg (6-7 lbs) in a month. However, because human discipline is inherently fragile, many people hit a stubborn “wall” when dieting.

Problem Statement: Lose 3–5 kg in 1 month
Challenge: Dieting is painful.

Proposed Method

Since restrictive diets are agonizing, let us consider a “Diet where you MUST eat”. The concept is simple: your only constraint for the day is that you must finish a specific massive dish. Beyond that, you are free to eat whatever you want.

Best Practices for Multi-Node Training on ABCI with PyTorch

Sun, 17 Dec 2023 00:00:00 +0000

This article summarizes a simple method for conducting distributed training with ABCI, the GPU cloud computing service operated by AIST. The following repository provides a minimal working example of training code on ABCI with support for multi-node training:

Simulating Charcoal Grilling at Home

Tue, 05 Dec 2023 00:00:00 +0000

Wall Advent Calendar 2023 Day 5

8 years since the first Wall Advent Calendar.
“A creative life lasts only 10 years.”
A quote that comes to mind with every returning Advent Calendar.

(This intro is completely unrelated to the rest of the post.)

Context: I want to eat charcoal-grilled food at home.
Problem: Lighting real charcoal indoors is inconvenient and dangerous.

Preparation

Purchase the following items:

Gas Torch / Culinary Blowtorch
Edible Bamboo Charcoal Powder
Spice shaker / condiment dispenser (from a 100-yen shop)

Fill the spice dispenser with the edible bamboo charcoal powder.

What Goes On Inside Image Generation AI?

Sun, 18 Sep 2022 00:00:00 +0000

This article explains the fundamental mechanisms behind image generation AI (such as text-to-image models) for non-engineers. As generative AI rapidly evolves, the goal is to provide an intuitive understanding of the underlying principles. For a more technical deep-dive, please refer to the foundational paper behind Stable Diffusion:

(arXiv link) High-Resolution Image Synthesis with Latent Diffusion Models

Images as Digital Data

First, let’s look at how computers represent images as data.

An image is an aggregation of pixels. A 1000 x 1000 image consists of 1,000,000 pixels. In standard digital imagery, each pixel is stored as an 8-bit integer (a number from 0 to 255), meaning any digital image is simply a collection of numerical values:

DIY Home Theater for Rental Apartments

This article is for Day 6 of the “Wall Advent Calendar 2021”.

Why Build a Home Theater?

Humans are creatures driven to install things on walls, and the undisputed king of wall-mounted aspirations for everyone is the “home theater.”

Popular Wall Installations by Gender Ranking 2021

Men	Women
1. Home Theater	1. Home Theater
2. Climbing Wall	2. Abstract painting by a college friend
3. Andy Warhol poster	3. Black-and-white Mads Mikkelsen poster

One major hurdle to building a home theater in Japan is that roughly 40% of housing consists of rental apartments. Unlike homeowners, tenants face strict constraints:

Adding Environment Variables for Arbitrary Users in Docker

Thu, 23 Jan 2020 00:00:00 +0000

Goal

When building a Docker image, we often install various C++ libraries. However, when working inside the container as a non-root user, header files may not be automatically included in the default search paths, which can be inconvenient.

We want to configure this neatly during the image build (inside the Dockerfile). However, the ENV directive only sets environment variables directly or for the root context, and might not always propagate properly to custom non-root users added later in certain shell sessions.

Did the Wedding Cross the Dimensional Wall?

A Wedding Crossing Dimensions

The other day, I attended a wedding ceremony between a friend of mine (the bride) and a 2D fictional character (the groom). Here is the bride’s own retrospective blog note:

Event Report

This article is an honest report of what happened that day. Note: Since the groom is an ultra-famous celebrity, clear photographs of him were strictly prohibited.

Setting Up a Home Theater in a Studio Apartment for Solo Living

Why Build a Home Theater?

Have you ever heard of a home theater? It’s literally a theater in your home. Enjoying movies and games on a massive screen is simply incredible. While it might sound daunting to set up, it’s actually much easier to achieve than you might think.

There is no strict definition of a home theater. Generally, it refers to a setup with a reasonably large screen accompanied by a solid speaker system (such as surround sound). Broadly speaking, setups are divided into TV-based and Projector-based configurations, each with its own pros and cons:

Walls of Singapore

Thu, 12 Dec 2019 00:00:00 +0000

This article is for Day 11 of the “Wall Advent Calendar 2019”. This year, the calendar hasn’t been overrun by artificial intelligence, making it a very wholesome calendar.

Though @azaazarashi will probably cause some chaos.

Singapore

Anyway, I went on a trip to Singapore.

This is a wall of the hotel I stayed at. It was white.

This is a painting of an old man on the wall of a beer bar I visited. Somehow he looks concerned about the future of this advent calendar.

Found some Superdry (極度乾燥) on a Singapore wall.

Craft Beer Bars

Speaking of craft beer, the Advent Calendar has been buzzing about Jokun Brewing Research Lab founded by Keihigu-shi and others. If you haven’t heard of them yet, make sure to check out their Twitter account and website:

Starting This Blog

Wed, 11 Dec 2019 00:00:00 +0000

It is said that distinguished engineers keep blogs, so I have resolved to start one of my own.

Purpose

A long time ago, I used to write tech articles on Hatena Blog. But that blog is no longer active, so I decided to set up a brand-new blog where I can write about a wider variety of miscellaneous topics.

Design

I don’t know much about HTML, but after some Googling, I found that building a static website automatically from Markdown using Hugo and hosting it on GitHub Pages seems to be the trendy approach, so I went with it.
