High-dimensional Bid Learning for Energy Storage Bidding in Energy Markets

no code implementations5 Nov 2023 Jinyu Liu, Hongye Guo, Qinghu Tang, En Lu, Qiuna Cai, Qixin Chen

To address this challenge, we modify the common reinforcement learning(RL) process by proposing a new bid representation method called Neural Network Embedded Bids (NNEBs).

Modality-Aware Contrastive Instance Learning with Self-Distillation for Weakly-Supervised Audio-Visual Violence Detection

1 code implementation12 Jul 2022 Jiashuo Yu, Jinyu Liu, Ying Cheng, Rui Feng, Yuejie Zhang

In this paper, we analyze the modality asynchrony and undifferentiated instances phenomena of the multiple instance learning (MIL) procedure, and further investigate its negative impact on weakly-supervised audio-visual learning.

Acoustic-to-articulatory Inversion based on Speech Decomposition and Auxiliary Feature

no code implementations2 Apr 2022 Jianrong Wang, Jinyu Liu, Longxuan Zhao, Shanyu Wang, Ruiguo Yu, Li Liu

Acoustic-to-articulatory inversion (AAI) is to obtain the movement of articulators from speech signals.

Bid Optimization using Maximum Entropy Reinforcement Learning

no code implementations11 Oct 2021 Mengjuan Liu, Jinyu Liu, Zhengning Hu, Yuchen Ge, Xuyun Nie

In this paper, we first utilize a widely accepted linear bidding function to compute every impression's base price and optimize it by a mutable adjustment factor derived from the RTB auction environment, to avoid optimizing every impression's bidding price directly.

Accurate Frequency Estimator of Sinusoid Based on Interpolation of FFT and DTFT

no code implementations journal 2020 Lei Fan, GUOQING QI2, Jun Xing, JIYU JIN, Jinyu Liu, AND ZHISEN WANG

The correlation coef cients between the Fourier Transform of the noises on two arbitrarily spaced spectrum lines are derived, and the MSE calculation formula is derived in additive white noise background based on the correlation coef cients.
