Emojional: Emoji Embeddings

Published in UK Workshop on Computational Intelligence, 2021

[2021UKCI] Emojis serve as visual language elements, transcending linguistic barriers but evolving in meaning based on context and emotions. Online, they play a role in cancel culture, with emojis like the clown or snake conveying subtle aggression. Novel emoji embeddings, emphasizing emotional content, outperform existing embeddings in sentiment analysis, capturing nuanced expressions effectively.

Decoding numeracy and literacy in the human brain: insights from MEG and MVPA

Published in Scientific Reports, 2023

[23SciRep] This study investigates the temporal dynamics of number and letter processing using magnetoencephalography (MEG) data from two experiments with 25 participants each. The results reveal an early dissociation (~100 ms) between numbers and letters compared to false fonts. Number processing remains consistent when presented as isolated items or in strings, while letter processing exhibits distinct classification accuracy for single items versus strings. The findings suggest that early visual processing is differentially influenced by experiences with numbers and letters, with a stronger dissociation observed for strings. This research was funded by Economic and Social Research Council (ESRC) funded Business and Local Government Data Research Centre under Grant ES/S007156/1.

Development of explainable AI-based predictive models for bubbling fluidised bed gasification process

Published in Fuel, 2023

[Fuel`23] The study focused on developing seven regression models to predict gas composition and gas yield, employing an Explainable AI (XAI) method for interpretability. The gradient boosting algorithm outperformed other regression-based models. The application of SHAP (Shapley additive explanations) values was utilized to elucidate the impact of input variables on the target. The results suggest that XAI, particularly when coupled with the gradient boosting algorithm, serves as a valuable tool for enhancing decision-making processes in fluidized bed gasifiers, providing transparency and interpretability to the predictive models. Code are available: GitHub

Machine Learning and Brain-Computer Interface

Published:

This talk was focused on Brain-Computer interfaceing. Brain-computer interface (BCI) is a collaboration between a brain and a device that enables signals from the brain to direct some external activity, such as control of a cursor or a prosthetic limb. The interface enables a direct communications pathway between the brain and the object to be controlled. I have discussed my research done during my PhD and Post-Doc.

Non-Stationary Learning in EEG-based Brain-Computer Interface

Published:

A common assumption in traditional supervised learning is the similar probability distribution of data between the training phase and the testing/operating phase. When transitioning from the training to testing phase, a shift in the probability distribution of input data is known as a covariate shift. Covariate shifts commonly arise in a wide range of real-world systems such as electroencephalogram-based brain–computer interfaces (BCIs). In such systems, there is a necessity for continuous monitoring of the process behavior, and tracking the state of the covariate shifts to decide about initiating adaptation in a timely manner. This talk focused on discussing methods to adapt to covariate shift.

Learning Under Dataset Shifts

Published:

Dataset shift is a challenging situation where the joint distribution of inputs and outputs differs between the training and test stages. Covariate shift is a simpler particular case of dataset shift where only the input distribution changes (covariate denotes input), while the conditional distribution of the outputs given the inputs p(y|x) remains unchanged. Dataset shift is present in most practical applications or reasons ranging from the bias introduced by experimental design, to the mere irreproducibility of the testing conditions at training time. For example, in an image classification task, training data might have been recorded under controlled laboratory conditions, whereas the test data may show different lighting conditions.

Python Intro Course

Published:

In this talk, I will focus Python Intro Course. This Introduction to Python course is for beginners. We aim to introduce fundamental programming concepts using Google Colab. We will introduce variables, data types, casting, string, Boolean, operators, lists, tuples, loops, conditions, functions, and a bit of NumPy. This course is designed for those who are coming from a non-technical background and willing to learn Python to great in summer school.

Introduction to Deep Learning & Neural Networks

Published:

In this talk, I will focus on the Introduction to Deep Learning & Neural Networks. Day 1 tutorial will focus on convolutional neural networks, also known as convnets, a type of deep-learning model almost universally used in computer vision applications. You’ll learn to apply convnets to image-classification problems—in particular, those involving small training datasets, which are the most common use case if you aren’t a large tech company.
Day 2 tutorial will focus on deep-learning models that can process text (understood as sequences of word or sequences of characters), time-series, and sequence data in general. The two-fundamental deep-learning algorithms for sequence processing are recurrent neural networks and 1D convnets. The applications of these algorithms are in document classification, time series classification, sequence to sequence learning and sentiment analysis.

Learning under Different Training and Testing Distributions

Published:

In this talk, I will focus on the Learning under Different Training and Testing Distributions. Systems based on machine learning methods often suffer a major challenge when applied to the real-world datasets. The conditions under which the system was developed will differ from those in which we use the system. Few sophisticated examples could be email spam filtering, stock prediction, health diagnostic, and brain-computer interface (BCI) systems, that took a few years to develop. Will this system be usable, or will it need to be adapted because the distribution has changed since the system was first built? Apparently, any form of real-world data analysis is cursed with such problems, which arise for reasons varying from the sample selection bias or operating in non-stationary environments. This tutorial will focus on the issues of dataset shifts (e.g. covariate shift, prior-probability shift, and concept shift) and will cover transfer learning for managing to learn a satisfactory model.
