The theoretical lens is that of...Show More
In automatic speech recognition (ASR), adaptation techniques are used to minimize the mismatch between training and testing conditions. Many successful techniques have been proposed for deep neural network (DNN) acoustic model (AM) adaptation. Recently, recurrent neural networks (RNNs) have outperformed DNNs in ASR tasks. However, the adaptation of RNN AMs is challenging and in some cases when com...Show More

The goal of defect detection is to detect and locate defects on product surface. Since the complexity of defect types in actual industrial production and it is difficult to obtain a large number of samples for supervised training. Current defect detection methods are thought to be mainly unsupervised training methods. However, the current unsupervised methods all learn the normal sample feature re...Show More
A Convolutional neural network (CNN) has emerged as a widely used approach to computer vision tasks, including object classification and detection tasks. The high requirement for the model to be more computationally efficient on lower information and communication technology (ICT) resource, e.g., mobile terminals can benefit from model distillation. However, most existing distillation methods suff...Show More

The analysis of this study is based on several variables including the input layer of the proposed ANN model as many as 28 parameters obtained from ...Show More
Deep neural networks are typically computationally expensive, thus, there is a strong motivation to develop less intensive models while maintaining performance. Distilling knowledge from a teacher network to a lightweight student network is a critical application of neural network compression where the student network can learn meaningful feature space and perform comparably to the teacher network...Show More
Given the outstanding performance of knowledge distillation networks in optimizing traditional deep neural networks, this paper proposes a distributed fusion network based on knowledge distillation. It leverages knowledge distillation techniques to partition the different branches of the distributed fusion network into teacher and student networks. Specifically, the branch modules responsible for ...Show More
Diverse applications such as criminal forensics and retail customer market segmentation would benefit from the ability to track individuals across multiple cameras. Clothing information is one of the keys to this capability when other identifying information such as the face cannot be reliably extracted. To quickly search for a criminal suspect or re-identify individuals across time and space, fil...Show More
Our paper proposes an unsupervised learning framework for knowledge distillation based on teacher-student networks for anomaly detection and classification in secure document images. The teacher network uses Wide-ResNet-50 as the backbone network and is pre-trained on large datasets of secure document images and ImageNet. We use a multi-scale feature pyramid matching strategy, so that the student ...Show More
The effectiveness of Physical Education (PE) teaching based on Deep Learning (DL) aims to maximum college students by addressing current deficiencies in college teachers' teaching abilities.

This paper proposes using the Levy Flight Mother Optimization Algorithm (LFMOA) method...Show More
This study uses social network analysis to analyze teacher social capital in a NSF-funded, DRK-12 cyber-enabled engineering education teacher professional development program. The social capital leveraged among the teachers can be visually represented by attributes such as schools, grades, cohorts, and subgroups. Each teacher's social capital is calculated to complement the analysis.Show More

Deep neural networks have achieved state-of-the-art performance in various fields. However, DNNs need to be scaled down to fit real-word applications where memory and computation resources are limited. As a means to compress the network yet still maintain the performance of the network, knowledge distillation has brought a lot of attention. This technique is based on the idea to train a student ne...Show More
This paper investigates techniques to transfer information between deep neural networks. We demonstrate that a student network, which has access to information computed by a teacher network on the training data, learns faster, can be less deep and requires less labeled examples to achieve a given performance level. For that we force the student to mimic the teacher by adding a penalty term to the ...Show More
