LaSCal: Label-Shift Calibration without target labels

Neural Information Processing Systems

When machine learning systems face dataset shift, model calibration plays a pivotal role in ensuring their reliability.Calibration error (CE) provides insights into the alignment between the predicted confidence scores and the classifier accuracy.While prior works have delved into the implications of dataset shift on calibration, existing CE estimators either (i) assume access to labeled data from the target domain, often unavailable in practice, or (ii) are derived under a covariate shift assumption.In this work we propose a novel, label-free, consistent CE estimator under label shift. Label shift is characterized by changes in the marginal label distribution p(Y), with a constant conditional p(X Y) distribution between the source and target. We introduce a novel calibration method, called LaSCal, which uses the estimator in conjunction with a post-hoc calibration strategy, to perform unsupervised calibration on the target distribution. Our thorough empirical analysis demonstrates the effectiveness and reliability of the proposed approach across different modalities, model architectures and label shift intensities.


This OnlyFans model found her photos on Reddit -- with someone elses face

Mashable

As an OnlyFans creator, she's learned to live with the exhausting, infuriating cycle of impersonation that comes with the territory. Five years in, she knows the drill. But this time felt different. The account in question hit too close. Everything checks out, but that is not her face.


Pope Leo's Name Carries a Warning About the Rise of AI

TIME - Tech

With his name choice and speech, Leo XIV firmly marks AI as a defining challenge facing our world today. But also embedded in the name is a potential path forward. Leo XIII, during his papacy, laid out a vision for protecting workers against tech-induced consolidation, including minimum wage laws and trade unions. His ideas soon gained influence and were implemented in government policies around the world. While it's still unclear what specific guidance Leo XIV may issue on artificial intelligence, history suggests the implications of his crusade could be profound.

Riverside wants to become 'the new Detroit.' Can this self-driving electric bus get it there?

Los Angeles Times

There is a little shuttle bus in the Inland Empire that's fueled with big aspirations. It's electric, tops out at 25 mph, and can only go on a pre-designated route set up by the Riverside Transit Agency. But here's a catch -- it also drives itself. As of Monday, commuters in Riverside are the first in the country to ride a fully self-driving, publicly accessible bus that is deployed by a city transit agency. "I like to say I have no lesser ambition than to be the new Detroit for vehicle manufacturing," Riverside Mayor Lock Dawson said.


Deep Learning without Weight Transport

Neural Information Processing Systems

Current algorithms for deep learning probably cannot run in the brain because they rely on weight transport, where forward-path neurons transmit their synaptic weights to a feedback path, in a way that is likely impossible biologically. An algorithm called feedback alignment achieves deep learning without weight transport by using random feedback weights, but it performs poorly on hard visual-recognition tasks. Here we describe two mechanisms -- a neural circuit called a weight mirror and a modification of an algorithm proposed by Kolen and Pollack in 1994 -- both of which let the feedback path learn appropriate synaptic weights quickly and accurately even in large networks, without weight transport or complex wiring. Tested on the ImageNet visual-recognition task, these mechanisms outperform both feedback alignment and the newer sign-symmetry method, and nearly match backprop, the standard algorithm of deep learning, which uses weight transport.


Predicting Future Actions of Reinforcement Learning Agents

Neural Information Processing Systems

As reinforcement learning agents become increasingly deployed in real-world scenarios, predicting future agent actions and events during deployment is important for facilitating better human-agent interaction and preventing catastrophic outcomes. This paper experimentally evaluates and compares the effectiveness of future action and event prediction for three types of RL agents: explicitly planning, implicitly planning, and non-planning. We employ two approaches: the inner state approach, which involves predicting based on the inner computations of the agents (e.g., plans or neuron activations), and a simulation-based approach, which involves unrolling the agent in a learned world model. Our results show that the plans of explicitly planning agents are significantly more informative for prediction than the neuron activations of the other types. Furthermore, using internal plans proves more robust to model quality compared to simulation-based approaches when predicting actions, while the results for event prediction are more mixed.

Pipeline Parallelism with Controllable Memory

Neural Information Processing Systems

Pipeline parallelism has been widely explored, but most existing schedules lack a systematic methodology. In this paper, we propose a framework to decompose pipeline schedules as repeating a building block, and show that the lifespan of the building block decides the peak activation memory of the pipeline schedule. Guided by the observations, we find that almost all existing pipeline schedules, to the best of our knowledge, are memory inefficient. To address this, we introduce a family of memory efficient building blocks with controllable activation memory, which can reduce the peak activation memory to 1/2 of 1F1B without sacrificing efficiency, and even to 1/3 with comparable throughput. We can also achieve almost zero pipeline bubbles while maintaining the same activation memory as 1F1B.
