On the Sample Complexity of Learning with Geometric Stability
Bietti, Alberto, Venturi, Luca, Bruna, Joan
Many supervised learning problems involve high-dimensional data such as images, text, or graphs. In order to make efficient use of data, it is often useful to leverage certain geometric priors in the problem at hand, such as invariance to translations, permutation subgroups, or stability to small deformations. We study the sample complexity of learning problems where the target function presents such invariance and stability properties, by considering spherical harmonic decompositions of such functions on the sphere. We provide non-parametric rates of convergence for kernel methods, and show improvements in sample complexity by a factor equal to the size of the group when using an invariant kernel over the group, compared to the corresponding non-invariant kernel. These improvements are valid when the sample size is large enough, with an asymptotic behavior that depends on spectral properties of the group. Finally, these gains are extended beyond invariance groups to also cover geometric stability to small deformations, modeled here as subsets (not necessarily subgroups) of permutations.
Deep Bayesian Unsupervised Lifelong Learning
Zhao, Tingting, Wang, Zifeng, Masoomi, Aria, Dy, Jennifer
Lifelong Learning (LL) refers to the ability to continually learn and solve new problems with incremental available information over time while retaining previous knowledge. Much attention has been given lately to Supervised Lifelong Learning (SLL) with a stream of labelled data. In contrast, we focus on resolving challenges in Unsupervised Lifelong Learning (ULL) with streaming unlabelled data when the data distribution and the unknown class labels evolve over time. Bayesian framework is natural to incorporate past knowledge and sequentially update the belief with new data. We develop a fully Bayesian inference framework for ULL with a novel end-to-end Deep Bayesian Unsupervised Lifelong Learning (DBULL) algorithm, which can progressively discover new clusters without forgetting the past with unlabelled data while learning latent representations. To efficiently maintain past knowledge, we develop a novel knowledge preservation mechanism via sufficient statistics of the latent representation for raw data. To detect the potential new clusters on the fly, we develop an automatic cluster discovery and redundancy removal strategy in our inference inspired by Nonparametric Bayesian statistics techniques. We demonstrate the effectiveness of our approach using image and text corpora benchmark datasets in both LL and batch settings.

Best Universities for Artificial Intelligence (AI) Programs
Artificial Intelligence (AI) is one of the most exciting research areas being conducted nowadays, and it has seen much popularity in recent years. Several universities now offer specialized degrees within AI, and some major ones offer a broader focus within Computer Science, Machine Learning, or other quantitative fields. While this list of the best university programs in artificial intelligence is not exhaustive, it provides a critical overview of some universities doing exceptional research in AI. Many of today's biggest tech companies are looking for individuals with a background in artificial intelligence (AI): Facebook, Apple, Google, to name a few, focus on this technology. It helps them improve and optimize their core business processes (with these new technologies, Facebook was able to obtain more than 2 billion registered users in a few years).
2021 Python for Machine Learning & Data Science Masterclass
This is currently in an Early Bird Beta access, meaning we are still going to be continually adding content to the course (even though we are already at over 20 hours of content!) Since we're still adding content and taking student feedback as we complete the course through the start of 2021, students who enroll now will get access to a wide variety of benefits! What do you get with Early Bird Access? You will get exclusive access to weekly live video streams where we will go through interactive machine learning projects! You'll be able to directly ask questions during the streams that will coincide with section launches corresponding to new machine learning algorithms added to the course content! These weekly streams will also include live Q&A with the instructor of the course, Jose Portilla.

Knowledge Consolidation based Class Incremental Online Learning with Limited Data
Karim, Mohammed Asad, Verma, Vinay Kumar, Singh, Pravendra, Namboodiri, Vinay, Rai, Piyush
This problem setting which necessitates a class incremental learning approach; is more challenging than standard class incremental learning (2) Data for each class is given in an online [Javed and White, 2019] due to additional constraints: (1) fashion, i.e., each training example is seen only once Data in each class appears in the online fashion, i.e., the model during training; (3) Each class has very few training sees every training example exactly once; (2) The number of examples; and (4) We do not use or assume access training examples in each class is very small; and (3) We do to any replay/memory to store data from previous not use any replay/memory to store the training examples from classes. Therefore, in this setting, we have to handle previous classes. This is the most general setting for class incremental twofold problems of catastrophic forgetting and learning and various practical usage scenario can be overfitting. In our approach, we learn robust representations obtained through this or a relaxed setting. For instance, in face that are generalizable across tasks without recognition, it is common to have few examples per class but suffering from the problems of catastrophic forgetting usually not in an online learning fashion, whereas for a robot and overfitting to accommodate future classes navigating in an environment, the setting would also be online.
