Securities-Based Lending or 股权质押 refers to the practice of making loans using securities as collateral. Securities-based lending provides ready access to capital that can be used for almost any purpose such as buying real estate, purchasing property like jewelry or a sports car, or investing in a business. The only restrictions to this kind of lending are other securities-based transactions like buying shares or repaying a margin loan.
This is my literature survey of landmark detection and 3D reconstruction for cat and dog’s face.
This is my reading note for Residual Parameter Transfer for Deep Domain Adaptation, which is for domain adaption. Different from existing methods, which mostly aims to learn a network to adpat the (feature) of target domain to the source domain, this paper learns a transform on the parameters of network trained on source domain to the network for the target domain.
This post we studies the profit of call options for different strike price and price change. The goal is for the given current price and volacity level, expiration date and ticket, find the most profitable strike price for different future price change. Please read Option Pricing Model for background knowledge the option pricing.
This is the my reading list of papers on domain adaption. This list is based on paperswithcode
Google Brain proposed MLP-Mixer (code is available in google-research/vision_transformer official) which solely used multi-perceptron network (MLP) for computer vision tasks. This is different most commonly used convolution neural network (CNN) or more recently transformer based approaches. The experiment on image classification indicates that, given sufficient amount of data (e.g., 100M images) for pre-training then fine-tuned for target task (ImageNet 2012), MLP-Mixer is able to achieve competitive result as CNN and transformer. However, the performance drops far belower than CNN when insufficient amount of data are available for pre-training, especially for its larger variation. It is also found at similar accuracy, MLP-Mixer and transformer are faster than CNN (ResNet) for inference and training by 2~3 times.
This is my reading note for GANFIT: Generative Adversarial Network Fitting for High Fidelity 3D Face Reconstruction. The code is available in GANFit. GANFit reconstructs high quality texture and geometry from a single image with precise identity recovery. To do this, it utilizes GANs to train a very powerful generator of facial texture in UV space. Then, it revisits the original 3D Morphable Models (3DMMs) fitting approaches making use of non-linear optimization to find the optimal latent parameters that best reconstruct the test image but under a new perspective. It optimizes the parameters with the supervision of pretrained deep identity features through our end-to-end differentiable framework.
An operating expense (OPEX) is an expense required for the day-to-day functioning of a business. In contrast, a capital expense (CAPEX) is an expense a business incurs to create a benefit in the future. Operating expenses and capital expenses are treated quite differently for accounting and tax purposes. This note is based on my reading of The Difference Between an Operating Expense vs. a Capital Expense
This is reading note for Avatarme: Realistically renderable 3d facial reconstruction ‘in-The-wild’, which was published in CVPR 2020 and code is available in github. Avatarme aims to reconstruct photorealistic 3D faces from a single “in-the-wild” image with an increasing level of detail. It could generate 4K by 6K-resolution 3D faces from a single low-resolution image that, for the first time, bridges the uncanny valley.
