Towards Extremely Compact RNNs for Video Recognition with Fully Decomposed Hierarchical Tucker Structure

arXiv.org Artificial Intelligence

Recurrent Neural Networks (RNNs) have been widely used in sequence analysis and modeling. However, when processing high-dimensional data, RNNs typically require very large model sizes, thereby bringing a series of deployment challenges. Although various prior works have been proposed to reduce the RNN model sizes, executing RNN models in resource-restricted environments is still a very challenging problem. In this paper, we propose to develop extremely compact RNN models with fully decomposed hierarchical Tucker (FDHT) structure. The HT decomposition does not only provide much higher storage cost reduction than the other tensor decomposition approaches but also brings better accuracy performance improvement for the compact RNN models. Meanwhile, unlike the existing tensor decomposition-based methods that can only decompose the input-to-hidden layer of RNNs, our proposed fully decomposition approach enables the comprehensive compression for the entire RNN models with maintaining very high accuracy. Our experimental results on several popular video recognition datasets show that our proposed fully decomposed hierarchical tucker-based LSTM (FDHT-LSTM) is extremely compact and highly efficient. To the best of our knowledge, FDHT-LSTM, for the first time, consistently achieves very high accuracy with only few thousand parameters (3,132 to 8,808) on different datasets. Compared with the state-of-the-art compressed RNN models, such as TT-LSTM, TR-LSTM and BT-LSTM, our FDHT-LSTM simultaneously enjoys both order-of-magnitude (3,985x to 10,711x) fewer parameters and significant accuracy improvement (0.6% to 12.7%).

After presenting a critical discussion of the key contributions in this area, we outline the current research challenges and emerging opportunities in this field.


Physics-informed neural networks for the shallow-water equations on the sphere

arXiv.org Artificial Intelligence

We propose the use of physics-informed neural networks for solving the shallow-water equations on the sphere. Physics-informed neural networks are trained to satisfy the differential equations along with the prescribed initial and boundary data, and thus can be seen as an alternative approach to solving differential equations compared to traditional numerical approaches such as finite difference, finite volume or spectral methods. We discuss the training difficulties of physics-informed neural networks for the shallow-water equations on the sphere and propose a simple multi-model approach to tackle test cases of comparatively long time intervals. We illustrate the abilities of the method by solving the most prominent test cases proposed by Williamson et al. [J. Comput. Phys. 102, 211-224, 1992].


Evaluating Predictive Business Process Monitoring Approaches on Small Event Logs

arXiv.org Artificial Intelligence

Predictive business process monitoring is concerned with the prediction how a running process instance will unfold up to its completion at runtime. Most of the proposed approaches rely on a wide number of different machine learning (ML) techniques. In the last years numerous comparative studies, reviews, and benchmarks of such approaches where published and revealed that they can be successfully applied for different prediction targets. ML techniques require a qualitatively and quantitatively sufficient data set. However, there are many situations in business process management (BPM) where only a quantitatively insufficient data set is available. The problem of insufficient data in the context of BPM is still neglected. Hence, none of the comparative studies or benchmarks investigates the performance of predictive business process monitoring techniques in environments with small data sets. In this paper an evaluation framework for comparing existing approaches with regard to their suitability for small data sets is developed and exemplarily applied to state-of-the-art approaches in predictive business process monitoring.


DeepWORD: A GCN-based Approach for Owner-Member Relationship Detection in Autonomous Driving

arXiv.org Artificial Intelligence

It's worth noting that the owner-member relationship between wheels and vehicles has an significant contribution to the 3D perception of vehicles, especially in the embedded environment. However, there are currently two main challenges about the above relationship prediction: i) The traditional heuristic methods based on IoU can hardly deal with the traffic jam scenarios for the occlusion. ii) It is difficult to establish an efficient applicable solution for the vehicle-mounted system. To address these issues, we propose an innovative relationship prediction method, namely DeepWORD, by designing a graph convolution network (GCN). Specifically, we utilize the feature maps with local correlation as the input of nodes to improve the information richness. Besides, we introduce the graph attention network (GAT) to dynamically amend the prior estimation deviation. Furthermore, we establish an annotated owner-member relationship dataset called WORD as a large-scale benchmark, which will be available soon. The experiments demonstrate that our solution achieves state-of-the-art accuracy and real-time in practice.


Deep Learning Tutorial for Beginners: A [Step-by-Step] Guide

#artificialintelligence

Deep Learning is a subdivision of machine learning that imitates the working of a human brain with the help of artificial neural networks. It is useful in processing Big Data and can create important patterns that provide valuable insight into important decision making. The manual labeling of unsupervised data is time-consuming and expensive. DeepLearning tutorials help to overcome this with the help of highly sophisticated algorithms that provide essential insights by analyzing and cumulating the data. Deep Learning leverages the different layers of neural networks that enable learning, unlearning, and relearning.


Toward deep-learning models that can reason about code more like humans

#artificialintelligence

Whatever business a company may be in, software plays an increasingly vital role, from managing inventory to interfacing with customers. Software developers, as a result, are in greater demand than ever, and that's driving the push to automate some of the easier tasks that take up their time. Productivity tools like Eclipse and Visual Studio suggest snippets of code that developers can easily drop into their work as they write. These automated features are powered by sophisticated language models that have learned to read and write computer code after absorbing thousands of examples. But like other deep learning models trained on big datasets without explicit instructions, language models designed for code-processing have baked-in vulnerabilities.


What Waymo's new leadership means for its self-driving cars

#artificialintelligence

Waymo, Alphabet's self-driving car subsidiary, is reshuffling its top executive lineup. On April 2, John Krafcik, Waymo's CEO since 2015, declared that he will be stepping down from his role. He will be replaced by Tekedra Mawakana and Dmitri Dolgov, the company's former COO and CTO. Krafcik will remain as an advisor to the company. "[With] the fully autonomous Waymo One ride-hailing service open to all in our launch area of Metro Phoenix, and with the fifth generation of the Waymo Driver being prepared for deployment in ride-hailing and goods delivery, it's a wonderful opportunity for me to pass the baton to Tekedra and Dmitri as Waymo's co-CEOs," Krafcik wrote on LinkedIn as he declared his departure.

Deformable Convolutions Demystified

#artificialintelligence

The reader of the post must have a basic understanding of Convolutional Neural Networks. If you are unfamiliar with the topic you can refer to this link and if you want to know more about the convolutional operation which is actually derived from basic image processing, you can read this blogpost as well. Convolutional Neural Networks or CNN's, in short, is one of the main causes of the revival of artificial intelligence research after a very long AI winter. The applications based on them were the first ones which showcased the power of artificial intelligence or deep learning to be precise and revived the faith in the field which was lost after Marvin Minsky pointed out that Perceptron just worked on linearly separable data and failed to work on the simplest non-linear functions such as XOR. Convolutional Neural Networks are very popular in the domain of Computer Vision and almost all state of the art applications such as google images, self-driving cars etc are based on them.
