• Improving hybrid-layer convolutional neural network system for lung cancer nodule classification using enhanced weight optimisation algorithm  
  by Vikul Pawar, P. Premchand 
  Abstract: In recent times, lung cancer is evolving as a highly life-threatening disease for human beings. According to the WHO, lung cancer disease is the second largest cause of deaths as compared to all other types of cancer. The prevailing available technology is striving to get more exposure in the field of medical science using Computer Assisted Diagnosis (CAD), where image processing is playing a crucial role for detecting the cancerous nodules in computer tomographic images. Augmenting the machine learning techniques with image processing algorithms is becoming a more comprehensive examination of cancer disease in proposed CAD systems. This paper is describes a heuristic approach for lung cancer nodule detection, and the proposed model predominantly consists of the following tasks, which are image enhancement, segmenting ROI (Region of Interest), features extraction, and nodule classification. In pre-processing, primarily the Adaptive Median Filter (AMF) filtering method is applied to eliminate the speckle noise from input CT images of Lung Image Database Consortium (LIDC) and Image Database Resource Initiative (IDRI): in the LIDC-IDRI dataset, the quality of input image is improved by applying Histogram Equalization (HE) technique with Contrast-Limited Adaptive (CLA) approach. Secondly, in the successive stage the Improved Level-Set (ILS) algorithm is used to segment the ROI. Furthermore, the third step of the projected work is applied to extract the definite learnable texture features and statistical features from the segmented ROI. The extracted features in the subsequent stage of classification are applied to Hybrid-Layer Convolutional Neural Network (HL-CNN) architecture to classify the lung cancer nodule as either benign or malignant. Principally this research is carried out by contributing to each stage of it, where the novel concept of the improved Hybrid-Layer Convolutional Neural Network (HL-CNN) is employed by optimising and selecting the optimal weight using the Enhanced Cat Swarm Optimisation (ECSO) algorithm. The experimental result of the proposed HL-CNN using the weight optimisation algorithm ECSO is achieved an accuracy of 93%, which is comparatively efficient with respect to existing models such as DBN, SVM, CNN, WOA, MFO, and CSO. Moreover, the proposed model conclusively gives a decision on the detected nodule as either benign or malignant.

• An unsupervised video summarisation method based on temporal convolutional networks  
  by Ke Jin, Haoran Li, Hui Li, Qichuang Liu, Rong Chen, Shikai Guo 
  Abstract: Video summarisation automatically select a sparse subset of video frames that best represent the semantic content of the input video. Previous work mainly used Long Short-Term Memory (LSTM) networks to learn how to assess the importance of each video frame and then select appropriate frames to compose a video summary. However, these models still represent shortcomings, such as limited memory capacity in handling long-term dependencies, and extended training time. Therefore, we present a deep video summarisation model, named TCN-SUM, which centres around Bi-TCN and models the frame sequence. TCN-SUM consists of three modules: frame selection module incorporates both Bidirectional Temporal Convolutional Network (Bi-TCN) and self-attention to model inter-frame dependencies, video reconstruction module reconstructs the original video based on the summary, and discriminator module measures the similarity between the original and reconstructed videos. Experimental studies on two benchmark datasets demonstrates that TCN-SUM outperforms state-of the- art techniques, achieving superior performance in unsupervised approaches and showing competitiveness compared to supervised methods.

  Abstract: The feature extraction and representation of chemical bond linear molecular structure from chemistry publication images is of great significance to rediscover the properties of chemical structure, but the rule-based method and the existing deep learning methods are facing the problem of low recognition rate. This paper presents ChemRAL, an automatic conversion model for chemical molecular images and identifiers. ChemRAL employs an encoder-decoder architecture with a ResNet residual network for image feature extraction, and an attention-based LSTM long-term memory network for converting molecular structure images into chemical identifiers. Comparative evaluations demonstrate that the ChemRAL model outperforms existing methods in terms of cross entropy loss and accuracy of the longest common subsequence. The conducted experiments have successfully showcased the advancements achieved by the ChemRAL model. The findings unequivocally indicate that ChemRAL not only enhances the precision and effectiveness of molecular image feature extraction and representation but also provides a significant benchmark.

• Assisted English Oral Teaching with Mouth Recognition Technology  
  by Shaoli Xiong, Rui Cong, Siew Eng Lin, Chunyan Ruan 
  Abstract: Deep learning-based speech emotion analysis has been widely applied in English oral teaching. Due to the close relationship between oral pronunciation and mouth shape, mouth recognition has received increasing attention to assist speech recognition. To effectively improve the effectiveness of English oral teaching, this paper constructs an efficient emotion analysis model by introducing human mouth-shape features. Specifically, we first use the Dlib tool to locate 68 facial landmarks and crop mouth-associated landmark information. To improve the extraction of mouth landmark features, we introduce the spatiotemporal graph convolutional network which can effectively mine spatial and temporal features from landmark information. In addition, to effectively model local and global dependencies, we utilise Focal-Transformer for speech feature extraction. To verify the effectiveness of our proposed model, we conducted extensive comparative experiments on two publicly available multimodal sentiment analysis datasets and the self-built English oral teaching dataset. All the experimental results confirm that our proposed model obtains a higher performance compared to other deep models.

• Building heating management based on deep learning to strengthen intelligent building design  
  by Yipeng Wang, ShiLin Zhang 
  Abstract: Building heating systems based on deep networks plays an important role in intelligent urban construction, providing a comfortable environment for residents. Accurate heating prediction can help operation and maintenance personnel grasp the energy demand of buildings in advance, avoiding unnecessary energy waste. To improve the long-term dependence between multiple variables, LSTM-based networks have been widely used in building heating prediction tasks. However, local dependencies cannot be utilized, and the model requires a large amount of computation. Therefore, this paper proposes a new Swin Transformer-based model for building heating system prediction. In addition, We use convolution operations for local dependency modeling. We conducted extensive experiments on our self-built dataset. All experimental results show that the proposed model achieves higher performance than LSTM and Transformer models.
