Continue — Exploring different LLM as assistant for web/app UX (2)

Background This is a follow up on previous article: Exploring different LLM as assistant for web/app UX Backgroundmedium.com The previous test was tested on 2023–08–05, I have reviewed the prompt and different LLM response, and make some refinement and see how the updated prompt being better or worse, as well as maybe there are some changes in the LLM themselves. Short recap of the test …

Exploring different LLM as assistant for web/app UX

Background I am facing a lot of web and app that provide poor UX, especially they are difficult to be used for those who are not familiar with using web/app (e.g. elderly like my mum who don’t even get familiar with usual web/app navigation or what icons they represent) There have…

Using GroundingDINO object detection on Apple Mac Mini M1

Intention The intention of this article is NOT to walk through in steps the steps manner, but focus on the gotchas I faced and an unexpected performance result. Setup I have a conda environment that have most required package installed, and the most important one is upgrade to PyTorch 2.0.1 (I tried…

Journey using CVAT semi-automatic annotation with a partially trained model to tag additional images (for further model tuning)

Background I have had 2 different object detection projects on hand lately, and the manual annotation of data from scratch have been a frustrating task One platform I used is the website MakeSense, that’s a very good project that the image annotation is run on browser directly. The problem of such…

Exploring using YOLOv8n with PyTorch Mobile (Android)

Background Given the previous experience on using YOLOv8 on Android through converting it from ONNX exported => Tensroflow => Tensorflow Lite (plus the realization on ditching tflite support object detection API and use plaint interpretor), there are following items that I am wondering if directly using PyTorch mobile would be a…

Continue the journey of adding Non Max Suppression (NMS) to YOLOv8 ONNX model — Fix issue(s) regarding convert the ONNX model to Tensorflow Lite and Tensorflow.js

Background In my previous article, I have been working on converting the Ultralytics YOLOv8 nano model into ONNX model with adding of non max suppression (NMS)operation, by “stitching” a ONNX NMS graph node in the original YOLOv8 nano converted model, plus adding another PyTorch model that particularly transform the “selected indices”…

Stitching non max suppression (NMS) to YOLOv8n on exported ONNX model

Background Following my previous post on exploring YOLOv8, I have been stuck at using the YOLOv8 model other than PyTorch, because the direct export model give result of dimension like [batch size, 5, 8400], which does encapsulated the result of overlapped bounding boxes and confidence score. But using this result in…

Exploring YOLOv8 for object detection (and compare it to YOLOv7 in terms of code and usage)

Background I have been exploring to train an computer vision object detection model and put into an Android device, the last time I have been exploring YOLOv7: Journey putting YOLO v7 model into TensorFlow Lite (Object Detection API) model running on Android Forewordsmedium.com Given YOLOv8 is out, I would like to see if there are any benefit to use YOLOv8 instead of YOLOv7. The flow and criterions

Powershell script to run backtrace inspection with PlatformIO xtensa-toolchain for ESP32

Background Following my previous post on inspecting backtrace message to see why the ESP32 crashed and reboot: Inspebacktrace / stack trace after ESP32 using espressif xtensa toolchain Backgroundstephencowchau.medium.com It’s very ineffective to trace 1 memory address at a time, so I wrote a powershell script for doing so, script as follow: To run the script, get to the location where the firmware.elf exist, which for PlatformIO, it’s your default Project folder > Project Name > .pio > build > (your env name, likely the board name, e.g. “nodemcu-32s”)
