Squirrel Problem

http://jsaezgallego.com/GlobCover_maps_squirrel/
该项目回答了以下简单的问题:松鼠能否在不接触地面的情况下从西班牙北部穿越到南部?

The answer is: obviously not. But, another question arises, 这个问题不太容易回答:如果一只松鼠必须从西班牙北部走到南部, 尽可能少地接触地面:它会朝哪个方向走?

The answer is not trivial, and it is answered here!

The project consisted of the following steps:
1. Download data from the internet. 该数据由GIS信息组成,用于确定一块土地是否为森林, a river, a man-made construction, and so on.
2. Create a path matrix. The squirrel takes one step at a time. 就栅格图而言,这意味着我们只能从相邻像素到达每个像素. Think of it as a huge spare matrix.
3. Optimize the path. 计算从西班牙顶部到底部的最短路径. 每个部分的成本是像素值,所以穿过森林不需要任何成本,而任何与水有关的东西都不可能穿过.
4. Visualize the solution as an interactive map.

Notification Bundler

http://github.com/jsga/bundle_notifications
A Python package for bundling notifications in event streams. 我们的目标是尽量减少发送给用户的通知数量,并且每天发送的通知不超过4个.

Avatar Generation with AI

http://infiniteavatarai.com
一个从头开始开发的全栈应用程序,可以用AI生成的漂亮的定制头像填充任何应用程序或设计. 成千上万的头像可用于许多预先存在的样式, and the possibility to generate your own. Includes a Python-based API deployed to a Kubernetes cluster.

ShowYourLocalStripes

http://showyourlocalstripes.com/
我创建了一个全栈应用程序,它从Open-Meteo检索历史天气数据,并生成说明全球气候变化的简单图表. 它利用谷歌定位服务为用户推荐地点. 该项目使用next、Tailwind和FastAPI构建,并部署在Kubernetes集群上. “ShowYourLocalStripes”旨在以一种用户友好的方式展示气候变暖, 灵感来自埃德·霍金斯最初的#展示你的条纹运动, with a focus on local warming trends.

Bird Audio Recognition

http://www.spinysoftware.com/chirpomatic/
我设计了一个深度学习模型,并利用音频数据实现了一个鸟类物种分类的后端系统. 该模型展示了一种独特的能力,可以区分同一物种的鸟类鸣叫. 后端基础设施已成功部署在Amazon Web Services (AWS)上,并且在高峰时段每小时处理超过500个请求.
