DreamFusion: Text-to-3D using 2D Diffusion, 2022.
Adapting this approach to 3D synthesis would require large-scale datasets of labeled 3D assets and efficient architectures for denoising 3D data, neither of which currently exist. In this work, we circumvent these limitations by using a pretrained 2D text-to-image diffusion model to perform text-to-3D synthesis. We introduce a loss based on probability density distillation that enables the use of a 2D diffusion model as a prior for optimization of a parametric image generator. Using this loss in a DeepDream-like procedure, we optimize a randomly-initialized 3D model (a Neural Radiance Field, or NeRF) via gradient descent such that its 2D renderings from random angles achieve a low loss

Zero-Shot Video Question Answering via Frozen Bidirectional Language Models
Zero-Shot Video Question Answering via Frozen Bidirectional Language Models
In particular, (i) we combine visual inputs with the frozen BiLM using light trainable modules, (ii) we train such modules using Web-scraped multi-modal data, and finally (iii) we perform zero-shot VideoQA inference through masked language modeling, where the masked text is the answer to a given question. Our proposed approach, FrozenBiLM, outperforms the state of the art in zero-shot VideoQA by a significant margin on a variety of datasets, including LSMDC-FiB, iVQA, MSRVTT-QA, MSVD-QA, ActivityNet-QA, TGIF-FrameQA, How2QA and TVQA. It also demonstrates competitive performance in the few-shot and fully-supervised setting. Our code and models will be made publicly available.

Second-Order Thinking: What Smart People Use to Outperform - Farnam Street
Second-order thinking is a mental model that smart people like Warren Buffett & Howard Marks use to avoid problems. Read this article to learn how it works.
Second order thinkers ask themselves the question “And then what?” This means thinking about the consequences of repeatedly eating a chocolate bar when you are hungry and using that to inform your decision. If you do this you’re more likely to eat something healthy.

What is Financial Modeling?
What is Financial Modeling?
Financial modeling is performed in Excel to forecast a company's financial performance. Read our overview and learn how and why to build a model.
A financial model is simply a spreadsheet which is usually built in Microsoft Excel, that forecasts a business’s financial performance into the future. The forecast is typically based on the company’s historical performance and assumptions about the future, and requires preparing an income statement, balance sheet, cash flow statement, and supporting schedules (known as a 3-statement model).

Financial modeling - Wikipedia
Financial modeling is the task of building an abstract representation (a model) of a real world financial situation.[1] This is a mathematical model designed to represent (a simplified version of) the performance of a financial asset or portfolio of a business, project, or any other investment. Typically, then, financial modeling is understood to mean an exercise in either asset pricing or corporate finance, of a quantitative nature. It is about translating a set of hypotheses about the behavior of markets or agents into numerical predictions.[2] At the same time, "financial modeling" is a general term that means different things to different users; the reference usually relates either to accounting and corporate finance applications or to quantitative finance applications. While there has been some debate in the industry as to the nature of financial modeling—whether it is a tradecraft, such as welding, or a science—the task of financial modeling has been gaining acceptance and rigor over the years

Accordingly, the cooperative principle is divided into Grice's four maxims of conversation, called the Gricean maxims—quantity, quality, relation, and manner. These four maxims describe specific rational principles observed by people who follow the cooperative principle in pursuit of effective communication

AlphaFold reveals the structure of the protein universe
Today, in partnership with EMBL’s European Bioinformatics Institute (EMBL-EBI), we’re now releasing predicted structures for nearly all catalogued proteins known to science, which will expand the AlphaFold DB by over 200x - from nearly 1 million structures to over 200 million structures - with the potential to dramatically increase our understanding of biology.

Eroom's law - Wikipedia
Eroom's law - Wikipedia
Eroom's law is the observation that drug discovery is becoming slower and more expensive over time, despite improvements in technology (such as high-throughput screening, biotechnology, combinatorial chemistry, and computational drug design), a trend first observed in the 1980s. The inflation-adjusted cost of developing a new drug roughly doubles every nine years.[1] In order to highlight the contrast with the exponential advancements of other forms of technology (such as transistors) over time, the name given to the observation is Moore's law spelled backwards.[2] The term was coined by Dr Jack Scannell and colleagues in 2012 in Nature Reviews Drug Discovery

Fermat's Library is a platform for illuminating academic papers.
The term "class size paradox" can be considered a generic term for all phenomena that arise where classes are of varied sizes, members of those classes disproportionately experience the larger classes, and most individ- uals therefore experience the average class size as larger than it is. Such phenomena are often more than mathematical curiosities; they have im- plications for how people experience and respond to various aspects of their environments.

GAAP: Understanding It and the 10 Key Principles
GAAP: Understanding It and the 10 Key Principles
GAAP is a common set of generally accepted accounting principles, standards, and procedures. U.S. public companies must follow GAAP for their financial statements.
GAAP is the set of accounting rules set forth by the FASB that U.S. companies must follow when putting together financial statements. GAAP aims to improve the clarity, consistency, and comparability of the communication of financial information. GAAP may be contrasted with pro forma accounting, which is a non-GAAP financial reporting method. The ultimate goal of GAAP is to ensure a company's financial statements are complete, consistent, and comparable. GAAP is used mainly in the U.S., while most other jurisdictions use the IFRS standards. 0 seconds of 1 minute, 43 secondsVolume 75%

Derivatives: Types, Considerations, and Pros and Cons
Derivatives: Types, Considerations, and Pros and Cons
A derivative is a securitized contract whose value is dependent upon one or more underlying assets. Its price is determined by fluctuations in that asset.
Derivatives are financial contracts, set between two or more parties, that derive their value from an underlying asset, group of assets, or benchmark. A derivative can trade on an exchange or over-the-counter. Prices for derivatives derive from fluctuations in the underlying asset. Derivatives are usually leveraged instruments, which increases their potential risks and rewards. Common derivatives include futures contracts, forwards, options, and swaps. 0 seconds of 1 minute, 8 secondsVolume 75%

Cross-Silo Federated Learning: Challenges and Opportunities
Cross-Silo Federated Learning: Challenges and Opportunities
Federated learning (FL) is an emerging technology that enables the training of machine learning models from multiple clients while keeping the data distributed and private. Based on the participating clients and the model training scale, federated learning can be classified into two types: cross-device FL where clients are typically mobile devices and the client number can reach up to a scale of millions; cross-silo FL where clients are organizations or companies and the client number is usually small (e.g., within a hundred). While existing studies mainly focus on cross-device FL, this paper aims to provide an overview of the cross-silo FL. More specifically, we first discuss applications of cross-silo FL and outline its major challenges. We then provide a systematic overview of the existing approaches to the challenges in cross-silo FL by focusing on their connections and differences to cross-device FL. Finally, we discuss future directions and open issues that merit research efforts from the community.

THE-X: Privacy-Preserving Transformer Inference with Homomorphic Encryption
THE-X: Privacy-Preserving Transformer Inference with Homomorphic Encryption
As more and more pre-trained language models adopt on-cloud deployment, the privacy issues grow quickly, mainly for the exposure of plain-text user data (e.g., search history, medical record, bank account). Privacy-preserving inference of transformer models is on the demand of cloud service users. To protect privacy, it is an attractive choice to compute only with ciphertext in homomorphic encryption (HE). However, enabling pre-trained models inference on ciphertext data is difficult due to the complex computations in transformer blocks, which are not supported by current HE tools yet. In this work, we introduce $\textit{THE-X}$, an approximation approach for transformers, which enables privacy-preserving inference of pre-trained models developed by popular frameworks. $\textit{THE-X}$ proposes a workflow to deal with complex computation in transformer networks, including all the non-polynomial functions like GELU, softmax, and LayerNorm. Experiments reveal our proposed $\textit{THE-X}$ can enable transformer inference on encrypted data for different downstream tasks, all with negligible performance drop but enjoying the theory-guaranteed privacy-preserving advantage.

Measuring human relationships and experiences
Measuring human relationships and experiences
With the lines between enterprises' stakeholders—customers, workers, and partners—blurring rapidly, creating a good human experience could begin with putting in place a holistic strategy to measure this experience.
The lines are blurring between what constitutes a worker, a business partner, or a customer, and the door between these relationships is no longer closed; it is a revolving one.
