- Autoencoders are unsupervised artificial neural networks useful for dimensionality reduction and clustering of unlabeled data. They compress the input into a latent-space representation and then reconstruct the output from this representation.
- Deep autoencoders, also known as stacked autoencoders, can learn hierarchical representations of the data by stacking multiple autoencoders together. The features learned by one autoencoder are used as the input for the next autoencoder in the stack.
- Variational autoencoders use probabilistic encoding and decoding to model the data distribution and can generate new samples from this distribution. They have been used for tasks like image generation, data manipulation, and unsupervised learning.

Autoencoders
An autoencoder is an artificial neural network that is trained to copy its input to its output. It consists of an encoder that compresses the input into a lower-dimensional latent-space encoding, and a decoder that reconstructs the output from this encoding. Autoencoders are useful for dimensionality reduction, feature learning, and generative modeling. When constrained by limiting the latent space or adding noise, autoencoders are forced to learn efficient representations of the input data. For example, a linear autoencoder trained with mean squared error performs principal component analysis.

Autoencoders are unsupervised neural networks that are trained to reconstruct their input. They compress the input into a latent space encoding and then decode the encoding to reconstruct the original input. Variations include denoising autoencoders, which are trained to reconstruct clean inputs from corrupted versions, and sparse autoencoders, which add regularization to activations to learn a sparse code. Contractive autoencoders add a penalty to make the hidden units invariant to small changes in input.

An autoencoder is a machine learning algorithm that represents unlabeled high-dimensional data as points in a low-dimensional space. A variational autoencoder (VAE) is an autoencoder that represents unlabeled high-dimensional data as low-dimensional probability distributions. In addition to data compression, the randomness of the VAE algorithm gives it a second powerful feature: the ability to generate new data similar to its training data. For example, a VAE trained on images of faces can generate a compelling image of a new "fake" face. It can also map new features onto input data, such as glasses or a mustache onto the image of a face that initially lacks these features. In this talk, we will survey VAE model designs that use deep learning, and we will implement a basic VAE in TensorFlow. We will also demonstrate the encoding and generative capabilities of VAEs and discuss their industry applications.

Volodymyr Lyubinets “Generative models for images”
Generative models for images can generate new samples from a target distribution or with particular properties. Variational autoencoders use an encoder to compress inputs into a latent representation and a decoder to reconstruct the input from that representation. Generative adversarial networks use a generator and discriminator that compete, with the generator trying to generate realistic samples and the discriminator trying to distinguish real from generated samples. CycleGAN uses GANs with cycle consistency to translate between image domains without paired data. Recent research includes Fader Networks for attribute transfer and semi-parametric image synthesis that reuses patterns from training data to generate new images conditioned on a semantic layout.

It provides an overview of the architecture of tile-based mobile GPUs like ImgTec SGX and how they process vertices and pixels in tiles. It then discusses optimizations for mobile like using multi-sample anti-aliasing to reduce memory usage, form-fitting alpha blended geometry, and avoiding buffer restores and resolves.

Denoising autoencoder by Harish.R
1) The document discusses using a denoising autoencoder to extract features from MNIST handwritten digit data to improve classification accuracy. It loads and preprocesses the noisy data, trains a denoising autoencoder on it, uses the hidden layers as new features, and trains a classifier on those features.
2) A convolutional denoising autoencoder is constructed and trained on noisy MNIST data, producing better reconstructions than a basic denoising autoencoder.
3) The pipeline extracts features from a denoising autoencoder trained on noisy MNIST data, uses those features to train a classifier, and achieves a validation accuracy of 99.71%, higher than training the same classifier on the original features.

The Next Mainstream Programming Language: A Game Developer's Perspective
Keynote at POPL 2006 by Tim Sweeney, Epic Games
Abstract:
Game developers have long been early adopters of new technologies. This is so because we are largely unburdened by legacy code: With each new hardware generation, we are free to rethink our software assumptions and develop new products using new tools and even new programming languages. As a result, games are fertile ground for applying academic advances in these areas.And never has our industry been in need of such advances as it is now! The scale and scope of game development has increased more than ten-fold over the past ten years, yet the underlying limitations of the mainstream C/C++/Java/C# language family remain largely unaddressed.The talk begins with a high-level presentation of the game developer's world: the kinds of algorithms we employ on modern CPUs and GPUs, the difficulties of componentization and concurrency, and the challenges of writing very complex software with real-time performance requirements.The talk then outlines the ways that future programming languages could help us write better code, providing examples derived from experience writing games and software frameworks that support games. The major areas covered are abstraction facilities -- how we can use them to develop more extensible frameworks and components; practical opportunities for employing stronger typing to reduce run-time failures; and the need for pervasive concurrency support, both implicit and explicit, to effectively exploit the several forms of parallelism present in games and graphics.
OCR for Urdu translation
The document discusses optical character recognition for Urdu handwriting. It introduces OCR and its applications. It then discusses earlier work on OCR systems that were font-specific. The document outlines the steps in OCR including image acquisition, preprocessing, segmentation, feature extraction, classification, and recognition. It provides an overview of the Urdu script and its variations. The document then summarizes research conducted on recognizing offline isolated Urdu characters using moment invariants and support vector machines. Other works discussed include an online and offline OCR system for Urdu using a segmentation-free approach, classifying Urdu ligatures using convolutional neural networks, and a segmentation-based approach for Urdu Nastaliq script recognition.

Natural Language Processing (NLP), RAG and its applications .pptx
1. In the realm of Natural Language Processing (NLP), knowledge-intensive tasks such as question answering, fact verification, and open-domain dialogue generation require the integration of vast and up-to-date information. Traditional neural models, though powerful, struggle with encoding all necessary knowledge within their parameters, leading to limitations in generalization and scalability. The paper "Retrieval-Augmented Generation for Knowledge-Intensive NLP Tasks" introduces RAG (Retrieval-Augmented Generation), a novel framework that synergizes retrieval mechanisms with generative models, enhancing performance by dynamically incorporating external knowledge during inference.
ViewShift: Hassle-free Dynamic Policy Enforcement for Every Data Lake
Dynamic policy enforcement is becoming an increasingly important topic in today’s world where data privacy and compliance is a top priority for companies, individuals, and regulators alike. In these slides, we discuss how LinkedIn implements a powerful dynamic policy enforcement engine, called ViewShift, and integrates it within its data lake. We show the query engine architecture and how catalog implementations can automatically route table resolutions to compliance-enforcing SQL views. Such views have a set of very interesting properties: (1) They are auto-generated from declarative data annotations. (2) They respect user-level consent and preferences (3) They are context-aware, encoding a different set of transformations for different use cases (4) They are portable; while the SQL logic is only implemented in one SQL dialect, it is accessible in all engines.

End-to-end pipeline agility - Berlin Buzzwords 2024
We describe how we achieve high change agility in data engineering by eliminating the fear of breaking downstream data pipelines through end-to-end pipeline testing, and by using schema metaprogramming to safely eliminate boilerplate involved in changes that affect whole pipelines.
A quick poll on agility in changing pipelines from end to end indicated a huge span in capabilities. For the question "How long time does it take for all downstream pipelines to be adapted to an upstream change," the median response was 6 months, but some respondents could do it in less than a day. When quantitative data engineering differences between the best and worst are measured, the span is often 100x-1000x, sometimes even more.
A long time ago, we suffered at Spotify from fear of changing pipelines due to not knowing what the impact might be downstream. We made plans for a technical solution to test pipelines end-to-end to mitigate that fear, but the effort failed for cultural reasons. We eventually solved this challenge, but in a different context. In this presentation we will describe how we test full pipelines effectively by manipulating workflow orchestration, which enables us to make changes in pipelines without fear of breaking downstream.
Making schema changes that affect many jobs also involves a lot of toil and boilerplate. Using schema-on-read mitigates some of it, but has drawbacks since it makes it more difficult to detect errors early. We will describe how we have rejected this tradeoff by applying schema metaprogramming, eliminating boilerplate but keeping the protection of static typing, thereby further improving agility to quickly modify data pipelines without fear.

The Building Blocks of QuestDB, a Time Series Database
Talk Delivered at Valencia Codes Meetup 2024-06.
Traditionally, databases have treated timestamps just as another data type. However, when performing real-time analytics, timestamps should be first class citizens and we need rich time semantics to get the most out of our data. We also need to deal with ever growing datasets while keeping performant, which is as fun as it sounds.
It is no wonder time-series databases are now more popular than ever before. Join me in this session to learn about the internal architecture and building blocks of QuestDB, an open source time-series database designed for speed. We will also review a history of some of the changes we have gone over the past two years to deal with late and unordered data, non-blocking writes, read-replicas, or faster batch ingestion.

A.为什么留学生需要操作留信认证?
留信认证全称全国留学生信息服务网认证,隶属于北京中科院。①留信认证门槛条件更低,费用更美丽,并且包过,完单周期短,效率高②留信认证虽然不能去国企,但是一般的公司都没有问题,因为国内很多公司连基本的留学生学历认证都不了解。这对于留学生来说,这就比自己光拿一个证书更有说服力,因为留学学历可以在留信网站上进行查询!
B.为什么我们提供的毕业证成绩单具有使用价值？
查询留服认证是国内鉴别留学生海外学历的唯一途径但认证只是个体行为不是所有留学生都操作所以没有办理认证的留学生的学历在国内也是查询不到的他们也仅仅只有一张文凭。所以这时候我们提供的和学校颁发的一模一样的毕业证成绩单就有了使用价值。只硕大的蛇皮袋手里拎着长铁钩正站在门口朝黑色的屋内张望不好坏人小偷山娃一怔却也灵机一动立马仰起头双手拢在嘴边朝楼上大喊：“爸爸爸——有人找——那人一听朝山娃尴尬地笑笑悻悻地走了山娃立马“嘭的一声将铁门锁死心却咚咚地乱跳当山娃跟父亲说起这事时父亲很吃惊抚摸着山娃的头说还好醒得及时要不家早被人掏空了到时连电视也没得看啰不过父亲还是夸山娃能临危不乱随机应变有胆有谋山娃笑笑说那都是书上学的看童话和小说时多
