Multimodal Token Fusion for Vision Transformers

11 code implementations journal 2022 Yikai Wang, Xinghao Chen, Lele Cao, Wenbing Huang, Fuchun Sun, Yunhe Wang

Many adaptations of transformers have emerged to address the single-modal vision tasks, where self-attention modules are stacked to handle input sources like images.

Simulation-Informed Revenue Extrapolation with Confidence Estimate for Scaleup Companies Using Scarce Time-Series Data

1 code implementation19 Aug 2022 Lele Cao, Sonja Horn, Vilhelm von Ehrenheim, Richard Anselmo Stahl, Henrik Landgren

Investment professionals rely on extrapolating company revenue into the future (i. e. revenue forecast) to approximate the valuation of scaleups (private companies in a high-growth stage) and inform their investment decision.

Simple, Scalable, and Stable Variational Deep Clustering

1 code implementation16 May 2020 Lele Cao, Sahar Asadi, Wenfei Zhu, Christian Schmidli, Michael Sjöberg

We then choose to focus on variational deep clustering (VDC) methods, since they mostly meet those criteria except for simplicity, scalability, and stability.

Prompt Tuned Embedding Classification for Multi-Label Industry Sector Allocation

1 code implementation21 Sep 2023 Valentin Leonhard Buchner, Lele Cao, Jan-Christoph Kalo, Vilhelm von Ehrenheim

All limitations (a), (b), and (c) are addressed by replacing the PLM's language head with a classification head, which is referred to as Prompt Tuned Embedding Classification (PTEC).

Sparse Coding and Dictionary Learning With Linear Dynamical Systems

no code implementations CVPR 2016 Wenbing Huang, Fuchun Sun, Lele Cao, Deli Zhao, Huaping Liu, Mehrtash Harandi

To enhance the performance of LDSs, in this paper, we address the challenging issue of performing sparse coding on the space of LDSs, where both data and dictionary atoms are LDSs.

Pay Self-Attention to Audio-Visual Navigation

no code implementations4 Oct 2022 Yinfeng Yu, Lele Cao, Fuchun Sun, Xiaohong Liu, Liejun Wang

Audio-visual embodied navigation, as a hot research topic, aims training a robot to reach an audio target using egocentric visual (from the sensors mounted on the robot) and audio (emitted from the target) input.

Using Deep Learning to Find the Next Unicorn: A Practical Synthesis

no code implementations18 Oct 2022 Lele Cao, Vilhelm von Ehrenheim, Sebastian Krakowski, Xiaoxue Li, Alexandra Lutz

The objective is a) to obtain a thorough and in-depth understanding of the methodologies for startup evaluation using DL, and b) to distil valuable and actionable learning for practitioners.

Sourcing Investment Targets for Venture and Growth Capital Using Multivariate Time Series Transformer

no code implementations28 Sep 2023 Lele Cao, Gustaf Halvardsson, Andrew McCornack, Vilhelm von Ehrenheim, Pawel Herman

This paper addresses the growing application of data-driven approaches within the Private Equity (PE) industry, particularly in sourcing investment targets (i. e., companies) for Venture Capital (VC) and Growth Capital (GC).

DISCOUNT: Distributional Counterfactual Explanation With Optimal Transport

no code implementations23 Jan 2024 Lei You, Lele Cao, Mattias Nilsson

This paper extends the concept of CEs to a distributional context, broadening the scope from individual data points to entire input and output distributions, named Distributional Counterfactual Explanation (DCE).

GenCeption: Evaluate Multimodal LLMs with Unlabeled Unimodal Data

no code implementations22 Feb 2024 Lele Cao, Valentin Buchner, Zineb Senane, Fangkai Yang

We propose GenCeption, a novel and annotation-free MLLM evaluation framework that merely requires unimodal data to assess inter-modality semantic coherence and inversely reflects the models' inclination to hallucinate.
