An Augmented Surprise-guided Sequential Learning Framework for Predicting the Melt Pool Geometry

no code implementations10 Jan 2024 Ahmed Shoyeb Raihan, Hamed Khosravi, Tanveer Hossain Bhuiyan, Imtiaz Ahmed

Our study introduces a novel surprise-guided sequential learning framework, SurpriseAF-BO, signaling a significant shift in MAM.

Generative Adversarial Network

Accelerating material discovery with a threshold-driven hybrid acquisition policy-based Bayesian optimization

no code implementations16 Nov 2023 Ahmed Shoyeb Raihan, Hamed Khosravi, Srinjoy Das, Imtiaz Ahmed

The UCB-to-EI switching policy dictated guided through continuous monitoring of the model uncertainty during each step of sequential sampling results in navigating through the MDS more efficiently while ensuring rapid convergence.

A Bi-LSTM Autoencoder Framework for Anomaly Detection -- A Case Study of a Wind Power Dataset

no code implementations17 Mar 2023 Ahmed Shoyeb Raihan, Imtiaz Ahmed

Anomalies refer to data points or events that deviate from normal and homogeneous events, which can include fraudulent activities, network infiltrations, equipment malfunctions, process changes, or other significant but infrequent events.

Anomaly Detection Time Series +1

Guiding the Sequential Experiments in Autonomous Experimentation Platforms through EI-based Bayesian Optimization and Bayesian Model Averaging

no code implementations26 Feb 2023 Ahmed Shoyeb Raihan, Imtiaz Ahmed

Afterward, we apply BMA to the same dataset by working with a set of predictive models and compare the performance of BMA with the traditional BO algorithm, which relies on a single model for approximation.
