A Novel Improved Mask RCNN for Multiple Targets Detection in the Indoor Complex Scenes

no code implementations7 Jan 2023 Zongmin Liu, Jirui Wang, Jie Li, Pengda Liu, Kai Ren

However, indoor scenes are usually complex and there are many types of interference factors, leading to great challenges in the multiple targets detection.

Memory-Sample Lower Bounds for Learning Parity with Noise

no code implementations5 Jul 2021 Sumegha Garg, Pravesh K. Kothari, Pengda Liu, Ran Raz

We show that any learning algorithm for the learning problem corresponding to $M$, with error, requires either a memory of size at least $\Omega\left(\frac{k \cdot \ell}{\varepsilon} \right)$, or at least $2^{\Omega(r)}$ samples.
