Carousel Memory: Rethinking the Design of Episodic Memory for Continual Learning
Lee, Soobee, Weerakoon, Minindu, Choi, Jonghyun, Zhang, Minjia, Wang, Di, Jeon, Myeongjae
Continual Learning (CL) is an emerging machine learning paradigm that aims to learn from a continuous stream of tasks without forgetting knowledge learned from the previous tasks. To avoid performance decrease caused by forgetting, prior studies exploit episodic memory (EM), which stores a subset of the past observed samples while learning from new non-i.i.d. Despite the promising results, since CL is often assumed to execute on mobile or IoT devices, the EM size is bounded by the small hardware memory capacity and makes it infeasible to meet the accuracy requirements for real-world applications. Specifically, all prior CL methods discard samples overflowed from the EM and can never retrieve them back for subsequent training steps, incurring loss of information that would exacerbate catastrophic forgetting. We explore a novel hierarchical EM management strategy to address the forgetting issue. In particular, in mobile and IoT devices, real-time data can be stored not just in high-speed RAMs but in internal storage devices as well, which offer significantly larger capacity than the RAMs. Based on this insight, we propose to exploit the abundant storage to preserve past experiences and alleviate the forgetting by allowing CL to efficiently migrate samples between memory and storage without being interfered by the slow access speed of the storage. We call it Carousel Memory (CarM). As CarM is complementary to existing CL methods, we conduct extensive evaluations of our method with seven popular CL methods and show that CarM significantly improves the accuracy of the methods across different settings by large margins in final average accuracy (up to 28.4%) while retaining the same training efficiency. With the rising demand for realistic on-device machine learning, recent years have witnessed a novel learning paradigm, namely continual learning (CL), for training neural networks (NN) with a stream of non-i.i.d. In such a paradigm, the neural network is incrementally learned with insertions of new tasks (e.g., a set of classes) (Rebuffi et al., 2017). The NN model is expected to continuously learn new knowledge from new tasks over time while retaining previously learned knowledge, which is a closer representation of how intelligent systems operate in the real world. In this learning setup, the knowledge should be acquired not only from the new data timely but also in a computationally efficient manner. In this regard, CL is suitable for learning on mobile and IoT devices (Hayes et al., 2020; Wang et al., 2019).
Mengzi: Towards Lightweight yet Ingenious Pre-trained Models for Chinese
Zhang, Zhuosheng, Zhang, Hanqing, Chen, Keming, Guo, Yuhang, Hua, Jingyun, Wang, Yulong, Zhou, Ming
Although pre-trained models (PLMs) have achieved remarkable improvements in a wide range of NLP tasks, they are expensive in terms of time and resources. This calls for the study of training more efficient models with less computation but still ensures impressive performance. Instead of pursuing a larger scale, we are committed to developing lightweight yet more powerful models trained with equal or less computation and friendly to rapid deployment. This technical report releases our pre-trained model called Mengzi, which stands for a family of discriminative, generative, domain-specific, and multimodal pre-trained model variants, capable of a wide range of language and vision tasks. Compared with public Chinese PLMs, Mengzi is simple but more powerful. Our lightweight model has achieved new state-of-the-art results on the widely-used CLUE benchmark with our optimized pre-training and fine-tuning techniques. Without modifying the model architecture, our model can be easily employed as an alternative to existing PLMs. Our sources are available at https://github.com/Langboat/Mengzi.
NeurIPS 2021 Competition IGLU: Interactive Grounded Language Understanding in a Collaborative Environment
Kiseleva, Julia, Li, Ziming, Aliannejadi, Mohammad, Mohanty, Shrestha, ter Hoeve, Maartje, Burtsev, Mikhail, Skrynnik, Alexey, Zholus, Artem, Panov, Aleksandr, Srinet, Kavya, Szlam, Arthur, Sun, Yuxuan, Hofmann, Katja, Galley, Michel, Awadallah, Ahmed
Human intelligence has the remarkable ability to adapt to new tasks and environments quickly. Starting from a very young age, humans acquire new skills and learn how to solve new tasks either by imitating the behavior of others or by following provided natural language instructions. To facilitate research in this direction, we propose IGLU: Interactive Grounded Language Understanding in a Collaborative Environment. The primary goal of the competition is to approach the problem of how to build interactive agents that learn to solve a task while provided with grounded natural language instructions in a collaborative environment. Understanding the complexity of the challenge, we split it into sub-tasks to make it feasible for participants. This research challenge is naturally related, but not limited, to two fields of study that are highly relevant to the NeurIPS community: Natural Language Understanding and Generation (NLU/G) and Reinforcement Learning (RL). Therefore, the suggested challenge can bring two communities together to approach one of the important challenges in AI. Another important aspect of the challenge is the dedication to perform a human-in-the-loop evaluation as a final evaluation for the agents developed by contestants.
Inferring Manifolds From Noisy Data Using Gaussian Processes
In analyzing complex datasets, it is often of interest to infer lower dimensional structure underlying the higher dimensional observations. As a flexible class of nonlinear structures, it is common to focus on Riemannian manifolds. Most existing manifold learning algorithms replace the original data with lower dimensional coordinates without providing an estimate of the manifold in the observation space or using the manifold to denoise the original data. This article proposes a new methodology for addressing these problems, allowing interpolation of the estimated manifold between fitted data points. The proposed approach is motivated by novel theoretical properties of local covariance matrices constructed from noisy samples on a manifold. Our results enable us to turn a global manifold reconstruction problem into a local regression problem, allowing application of Gaussian processes for probabilistic manifold reconstruction. In addition to theory justifying the algorithm, we provide simulated and real data examples to illustrate the performance.

System trains drones to fly around obstacles at high speeds
If you follow autonomous drone racing, you likely remember the crashes as much as the wins. In drone racing, teams compete to see which vehicle is better trained to fly fastest through an obstacle course. But the faster drones fly, the more unstable they become, and at high speeds their aerodynamics can be too complicated to predict. Crashes, therefore, are a common and often spectacular occurrence. But if they can be pushed to be faster and more nimble, drones could be put to use in time-critical operations beyond the race course, for instance to search for survivors in a natural disaster.
The Building Blocks of Meaningful AI Regulation
Buying a home is an important milestone many Americans dream about. Kids grow up doodling images of their dream home. College students start building their credit early so they can apply for a mortgage in the future. People save money for years so they can afford a downpayment. But, imagine if after all that dreaming and hard work, your hopes of buying a home are dashed by a biased lending algorithm that uses your race, or where you grew up, to determine your future. According to a recent investigation conducted by The Markup, this nightmare is a reality for many prospective borrowers in the United States.
Get started with Machine Learning Part 1
I have been working for many months to understand machine learning. It is the most agonizing experience but on the other hand, is a thrilled one. I don't have any experience related to IT or Advanced Calculus. Indeed, I learn calculus in my previous study in college but sometimes memory can fade if it does not use every day, am I correct? Therefore, I have to study the basics of machine learning.
