Highly-Efficient Binary Neural Networks for Visual Place Recognition

arXiv.org Artificial Intelligence

VPR is a fundamental task for autonomous navigation as it enables a robot to localize itself in the workspace when a known location is detected. Although accuracy is an essential requirement for a VPR technique, computational and energy efficiency are not less important for real-world applications. CNN-based techniques archive state-of-the-art VPR performance but are computationally intensive and energy demanding. Binary neural networks (BNN) have been recently proposed to address VPR efficiently. Although a typical BNN is an order of magnitude more efficient than a CNN, its processing time and energy usage can be further improved. In a typical BNN, the first convolution is not completely binarized for the sake of accuracy. Consequently, the first layer is the slowest network stage, requiring a large share of the entire computational effort. This paper presents a class of BNNs for VPR that combines depthwise separable factorization and binarization to replace the first convolutional layer to improve computational and energy efficiency. Our best model achieves state-of-the-art VPR performance while spending considerably less time and energy to process an image than a BNN using a non-binary convolution as a first stage.


Customer Experience in the Age of AI

#artificialintelligence

A personalized customer experience has become the basis for competitive advantage. However, providing personalization requires more than just a technological fix. Businesses must design intelligent experience engines, which assemble high-quality, end-to-end customer experiences using AI powered by customer data. Brinks is a 163-year-old business well-known for its fleet of armored trucks. The company also licenses its brand to a lesser-known, independently operated sister company, Brinks Home. The Dallas-based smart-home-technology business has struggled to gain brand recognition commensurate with the Brinks name. It competes against better-known systems from ADT, Google Nest, and Ring, and although it has earned stellar reviews from industry analysts and customers, its market share is only 2%.


Testing Granger Non-Causality in Panels with Cross-Sectional Dependencies

arXiv.org Machine Learning

Within the last decade, there has been growing awareness that causal inference can improve scientific research in many disciplines as interpretability and robustness become increasingly important (Doshi-Velez and Kim, 2017; Roscher et al., 2020; Marcinkeviฤs and Vogt, 2020; Moraffah et al., 2020). Causality is a crucial factor for gaining insights into the decision process of algorithms, which has many use cases such as avoiding bias and discrimination (Mehrabi et al., 2019), improving user experience (Zhou and Fu, 2007) and gathering biological insights (Angermueller et al., 2016). If the causal relation between variables is known, causality can be used to study the interaction between statistical units such as estimating the average effect of treatments (Imbens and Rubin, 2015; Holland, 1986), analyze their mediation (Berzuini et al., 2012), detect the root causes of anomalies (Janzing et al., 2019) or quantifying the causal influence of variables in a system (Janzing et al., 2013, 2020).


Netflix tests its TikTok-like comedy feed on TVs

Engadget

You didn't think Netflix would leave its TikTok-style comedy feed on phones, did you? Sure enough, the company is launching a test that brings the Fast Laughs feature to TVs. Opt in and you'll get a flurry of hopefully funny clips from Netflix shows, movies and (of course) comedy specials. Find something you enjoy and you can watch the whole affair or add it to your watch list. The addition is "slowly" deploying to subscribers in English-speaking countries including the US, Canada, UK, Ireland, Australia and New Zealand.


Many processors, little time: MCMC for partitions via optimal transport couplings

arXiv.org Machine Learning

Markov chain Monte Carlo (MCMC) methods are often used in clustering since they guarantee asymptotically exact expectations in the infinite-time limit. In finite time, though, slow mixing often leads to poor performance. Modern computing environments offer massive parallelism, but naive implementations of parallel MCMC can exhibit substantial bias. In MCMC samplers of continuous random variables, Markov chain couplings can overcome bias. But these approaches depend crucially on paired chains meetings after a small number of transitions. We show that straightforward applications of existing coupling ideas to discrete clustering variables fail to meet quickly. This failure arises from the "label-switching problem": semantically equivalent cluster relabelings impede fast meeting of coupled chains. We instead consider chains as exploring the space of partitions rather than partitions' (arbitrary) labelings. Using a metric on the partition space, we formulate a practical algorithm using optimal transport couplings. Our theory confirms our method is accurate and efficient. In experiments ranging from clustering of genes or seeds to graph colorings, we show the benefits of our coupling in the highly parallel, time-limited regime.


Five ways AI is saving wildlife โ€“ from counting chimps to locating whales

The Guardian

There's a strand of thinking, from sci-fi films to Stephen Hawking that suggests artificial intelligence (AI) could spell doom for humans. But conservationists are increasingly turning to AI as an innovative tech solution to tackle the biodiversity crisis and mitigate climate change. From camera trap and satellite images to audio recordings, the report notes: "AI can learn how to identify which photos out of thousands contain rare species; or pinpoint an animal call out of hours of field recordings โ€“ hugely reducing the manual labour required to collect vital conservation data." AI is helping to protect species as diverse as humpback whales, koalas and snow leopards, supporting the work of scientists, researchers and rangers in vital tasks, from anti-poaching patrols to monitoring species. With machine learning (ML) computer systems that use algorithms and models to learn, understand and adapt, AI is often able to do the job of hundreds of people, getting faster, cheaper and more effective results.

ALDI North Sydney launches new Pizzabot

Daily Mail - Science & tech

Aldi Australia has launched a first-of-its-kind robotic pizza vending machine dubbed a'Pizzabot' at its Corner Store in North Sydney - with flavours Pepperoni and Italiana currently available from $8.99. The snazzy new robotic technology - which can cook 450 pizzas a day - is serving up restaurant-grade gourmet pizza in just two minutes. The machine also has a glass front, giving pizza-lovers a front row seat to the theatre of their pizza being cooked and packaged by the robotic machine. The mechanism was created in collaboration with Bondi start-up Placer Robotics. Pizzabot is the first pizza vending machine to be designed and manufactured in Australia, and will debut exclusively at Aldi Corner Store in North Sydney.


L3DAS22 Challenge: Learning 3D Audio Sources in a Real Office Environment

arXiv.org Artificial Intelligence

The L3DAS22 Challenge is aimed at encouraging the development of machine learning strategies for 3D speech enhancement and 3D sound localization and detection in office-like environments. This challenge improves and extends the tasks of the L3DAS21 edition. We generated a new dataset, which maintains the same general characteristics of L3DAS21 datasets, but with an extended number of data points and adding constrains that improve the baseline model's efficiency and overcome the major difficulties encountered by the participants of the previous challenge. We updated the baseline model of Task 1, using the architecture that ranked first in the previous challenge edition. We wrote a new supporting API, improving its clarity and ease-of-use. In the end, we present and discuss the results submitted by all participants. L3DAS22 Challenge website: www.l3das.com/icassp2022.
