Meta-heuristic algorithms in car engine design: a literature survey

Meta-heuristic algorithms are often inspired by natural phenomena, including the evolution of species in Darwinian natural selection theory, ant behaviors in biology, flock behaviors of some birds, and annealing in metallurgy. Due to their great potential in solving difficult optimization problems, meta-heuristic algorithms have found their way into automobile engine design. There are different optimization problems arising in different areas of car engine management including calibration, control system, fault diagnosis, and modeling. In this paper we review the state-of-the-art applications of different meta-heuristic algorithms in engine management systems. The review covers a wide range of research, including the application of meta-heuristic algorithms in engine calibration, optimizing engine control systems, engine fault diagnosis, and optimizing different parts of engines and modeling. The meta-heuristic algorithms reviewed in this paper include evolutionary algorithms, evolution strategy, evolutionary programming, genetic programming, differential evolution, estimation of distribution algorithm, ant colony optimization, particle swarm optimization, memetic algorithms, and artificial immune system

Control and Analysis for Sequential Information based on Machine Learning

Sequential information is crucial for real-world applications that are related to time, which is same with time-series being described by sequence data followed by temporal order and regular intervals. In this thesis, we consider four major tasks of sequential information that include sequential trend prediction, control strategy optimisation, visual-temporal interpolation and visual-semantic sequential alignment. We develop machine learning theories and provide state-of-the-art models for various real-world applications that involve sequential processes, including the industrial batch process, sequential video inpainting, and sequential visual-semantic image captioning. The ultimate goal is about designing a hybrid framework that can unify diverse sequential information analysis and control systems For industrial process, control algorithms rely on simulations to find the optimal control strategy. However, few machine learning techniques can control the process using raw data, although some works use ML to predict trends. Most control methods rely on amounts of previous experiences, and cannot execute future information to optimize the control strategy. To improve the effectiveness of the industrial process, we propose improved reinforcement learning approaches that can modify the control strategy. We also propose a hybrid reinforcement virtual learning approach to optimise the long-term control strategy. This approach creates a virtual space that interacts with reinforcement learning to predict a virtual strategy without conducting any real experiments, thereby improving and optimising control efficiency. For sequential visual information analysis, we propose a dual-fusion transformer model to tackle the sequential visual-temporal encoding in video inpainting tasks. Our framework includes a flow-guided transformer with dual attention fusion, and we observe that the sequential information is effectively processed, resulting in promising inpainting videos. Finally, we propose a cycle-based captioning model for the analysis of sequential visual-semantic information. This model augments data from two views to optimise caption generation from an image, overcoming new few-shot and zero-shot settings. The proposed model can generate more accurate and informative captions by leveraging sequential visual-semantic information. Overall, the thesis contributes to analysing and manipulating sequential information in multi-modal real-world applications. Our flexible framework design provides a unified theoretical foundation to deploy sequential information systems in distinctive application domains. Considering the diversity of challenges addressed in this thesis, we believe our technique paves the pathway towards versatile AI in the new era

Research on Brain and Mind Inspired Intelligence

To address the problems of scientific theory, common technology and engineering application of multimedia and multimodal information computing, this paper is focused on the theoretical model, algorithm framework, and system architecture of brain and mind inspired intelligence (BMI) based on the structure mechanism simulation of the nervous system, the function architecture emulation of the cognitive system and the complex behavior imitation of the natural system. Based on information theory, system theory, cybernetics and bionics, we define related concept and hypothesis of brain and mind inspired computing (BMC) and design a model and framework for frontier BMI theory. Research shows that BMC can effectively improve the performance of semantic processing of multimedia and cross-modal information, such as target detection, classification and recognition. Based on the brain mechanism and mind architecture, a semantic-oriented multimedia neural, cognitive computing model is designed for multimedia semantic computing. Then a hierarchical cross-modal cognitive neural computing framework is proposed for cross-modal information processing. Furthermore, a cross-modal neural, cognitive computing architecture is presented for remote sensing intelligent information extraction platform and unmanned autonomous system

Generalised additive multiscale wavelet models constructed using particle swarm optimisation and mutual information for spatio-temporal evolutionary system representation

A new class of generalised additive multiscale wavelet models (GAMWMs) is introduced for high dimensional spatio-temporal evolutionary (STE) system identification. A novel two-stage hybrid learning scheme is developed for constructing such an additive wavelet model. In the first stage, a new orthogonal projection pursuit (OPP) method, implemented using a particle swarm optimisation(PSO) algorithm, is proposed for successively augmenting an initial coarse wavelet model, where relevant parameters of the associated wavelets are optimised using a particle swarm optimiser. The resultant network model, obtained in the first stage, may however be a redundant model. In the second stage, a forward orthogonal regression (FOR) algorithm, implemented using a mutual information method, is then applied to refine and improve the initially constructed wavelet model. The proposed two-stage hybrid method can generally produce a parsimonious wavelet model, where a ranked list of wavelet functions, according to the capability of each wavelet to represent the total variance in the desired system output signal is produced. The proposed new modelling framework is applied to real observed images, relative to a chemical reaction exhibiting a spatio-temporal evolutionary behaviour, and the associated identification results show that the new modelling framework is applicable and effective for handling high dimensional identification problems of spatio-temporal evolution sytems
