A Riemannian Geometry for Low-rank Adaptation

Shoichiro Takeda, Shin'ya Yamaguchi, Satoshi Suzuki +1

Low-rank adaptation (LoRA) is widely used as a parameter-efficient fine-tuning technique for pre-trained deep neural networks, which approximates the weight update via full fine-tu…

A Tractable Continuous-Time Model for Designing Interventions for Time-Inconsistent Agents

Yasunori Akagi, Hideaki Kim, Daichi Fushihara +3

Designing effective goals and rewards for time-inconsistent agents is a central problem in many long-term tasks, such as learning, exercise, work, and project completion. An agent…

Delta Matters: An Analytically Tractable Model for - Discounting Agents

Yasunori Akagi, Takeshi Kurashima

Humans exhibit time-inconsistent behavior, in which planned actions diverge from executed actions. Understanding time inconsistency and designing appropriate interventions is a key…

A Continuous-time Tractable Model for Present-biased Agents

Yasunori Akagi, Hideaki Kim, Takeshi Kurashima

Present bias, the tendency to overvalue immediate rewards while undervaluing future ones, is a well-known barrier to achieving long-term goals. As artificial intelligence and behav…

Joint Pricing and Matching for Resource Allocation Platforms via Min-cost Flow Problem

Yuya Hikima, Yasunori Akagi, Hideaki Kim

Stochastic matching is the stochastic version of the well-known matching problem, which consists in maximizing the rewards of a matching under a set of probability distributions as…

Optimal Transport with Cyclic Symmetry

Shoichiro Takeda, Yasunori Akagi, Naoki Marumo +1

We propose novel fast algorithms for optimal transport (OT) utilizing a cyclic symmetry structure of input data. Such OT with cyclic symmetry appears universally in various real-wo…

Analytically Tractable Models for Decision Making under Present Bias

Yasunori Akagi, Naoki Marumo, Takeshi Kurashima

Time-inconsistency is a characteristic of human behavior in which people plan for long-term benefits but take actions that differ from the plan due to conflicts with short-term ben…

Aggregated Multi-output Gaussian Processes with Knowledge Transfer Across Domains

Yusuke Tanaka, Toshiyuki Tanaka, Tomoharu Iwata +4

Aggregate data often appear in various fields such as socio-economics and public security. The aggregate data are associated not with points but with supports (e.g., spatial region…

Non-approximate Inference for Collective Graphical Models on Path Graphs via Discrete Difference of Convex Algorithm

Yasunori Akagi, Naoki Marumo, Hideaki Kim +2

The importance of aggregated count data, which is calculated from the data of multiple individuals, continues to increase. Collective Graphical Model (CGM) is a probabilistic appro…

Spatially Aggregated Gaussian Processes with Multivariate Areal Outputs

Yusuke Tanaka, Toshiyuki Tanaka, Tomoharu Iwata +4

We propose a probabilistic model for inferring the multivariate function from multiple areal data sets with various granularities. Here, the areal data are observed not at location…
