AI Chatbot on Custom Data

I worked on a proof of concept (POC) to customize a GPT-based AI chatbot on internal company data. It can process both natural language and tabular data. It relies on OpenAI APIs and LangChain. The system can deliver high-quality, up-to-date answers on proprietary data.

Generative AI Platform

I developed a platform that can be used to fine-tune generative models (e.g., stable diffusion) to custom subjects The platform utilized Hugging Face for the modeling framework and Ray Serve for the serving and training. The whole platform (front-end, back-end, and model pipelines) was deployed in a Kubernetes cluster; the Ray deployment leveraged Kuberay to manage the lifecycle of the different components.

Process Optimization System

I developed a system to optimize distillation sequences and parameters for non-ideal mixtures. The system significantly reduced the time required for process engineers to design systems that meet requirements.

Pixel-perfect Instance Segmentation

I developed a deep learning pipeline for an application that required pixel-perfect segmentation masks for retail. It involved carefully selecting and combining state-of-the-art models to achieve the required performance.

AI for Drug Discovery

I contributed to an industry disruptive startup that aims to solve drug discovery with AI. I worked on software engineering and DevOps for large-scale cluster systems to support the research team and designed and implemented a system architecture that made experimentation more cost-efficient and faster. Also, I proposed architectural changes to the research team regarding generative models.

Financial Timeseries Prediction

I worked on a proof of concept for a financial forecasting model that involved large amounts of unevenly spaced time series data. I developed a PyTorch data loader interface to an SQL data warehouse to efficiently train models at scale and tailored deep learning models.

AI Artist Demo

https://www.cambridgeconsultants.com/vincent
I worked on a machine learning technology demonstration that turned sketches into art pieces. I built on top of cutting-edge deep learning architectures using generative adversarial networks to create a system that can hallucinate artistic paintings based on the input edges. I used Python with TensorFlow to build the architecture, implement the data pipeline and facilitate distributed training. Since the work we've done for clients was confidential, this demo could perfectly showcase the team's capability, and this demo, in particular, had a significant impact on our presence in the AI consulting domain.

Beyond Human Vision Demo

https://www.cambridgeconsultants.com/deepray
This technology demonstration aimed to reconstruct distorted images, so the model did pixel-wise mapping and had to fill in missing information based on the context. Generative adversarial networks are excellent at doing this, and it was shown how the model could change the output depending on the environment. I used Python with PyTorch for the training and a Flask back-end with a TypeScript front-end for the deployed system.

Artificial Neural Network Based Adaptive Non-linear Control

I worked on a non-linear controller that can learn the system dynamics that it controls. An artificial neural network is trained online to predict the system states to provide better performance than a simple PID algorithm. It was applied to a simple two-degrees-of-freedom robotic arm to prove the concept. I developed the prototype's mechanics and electronics, simulated the dynamics in C++, and deployed the system to a low-cost Atmel microcontroller using Embedded C.

Humanoid Walking Robot

I developed a system design for a humanoid walking robot and simulated and prototyped the control algorithm using Simulink. I implemented the Linux middleware for the actuators and sensors on the onboard controller.

IMAV 2017 Virtual Challenge

http://www.imavs.org/2017/virtual-challenge.1.html
I worked on the simulation environment for the IMAV drone competition. I used Gazebo, ROS, and Simulink to provide a high-fidelity simulation that can be used to evaluate autonomous flight controllers.

Reinforcement Learning-based Crypto Trading Bot

I developed an RL agent for cryptocurrency trading that uses OHLCV data and technical indicators, and the model has been developed using PyTorch and Ray, which enables massive scaling to reduce the training time significantly. The model was trained and backtested with data from the last few years, and it showed promising results, outperforming baseline strategies.

To find the best-performing agent, I evaluated different RL algorithms (PPO, IMPALA) and model architectures (fully connected, convolutional, attention-based).

For backtesting and live trading, I used Freqtrade.

Manufacturing Monitoring IoT Device

I developed an IoT device that can be attached to injection molding machines to monitor different characteristics based on the measured temperature and piston velocity. This data was then used to create a digital twin of the machines, which provided predictive maintenance capabilities and general insight into the machine's health.

BMS IoT Scanning and Management

I worked on an IoT scanner that specifically targets devices used in building management services (BMS) to control systems like HVAC, lighting, etc. The tool scanned the network and gathered useful information about the broad range of devices used within the building.
