Recently Google AI team presented a set of neural networks, allowing robots to be trained to move one-, two- and three-dimensional deformable objects. The code opens up opportunities for increasing the level of automation in manufacturing.
About the problem
The difficulty that arises when manipulating a deformable object lies in the impossibility of completely setting its configuration. For example, to describe the location of a rigid cube in three-dimensional space, it is sufficient to indicate the position of a fixed point relative to its center, but in an object such as a cloth, the position of all its points changes relative to each…

How to use Python and Dash library to create, style, and host an interactive data analysis web application.
If not long ago the creation of analytical web applications required knowledge of several programming languages, today you can create a data visualization interface in pure Python. One popular tool for this has become Dash, which allows data scientists to display results in interactive web applications.
In this guide, we’ll cover:
- How to create a Dash app
- Main library components
- How to customize the app style
- How to make an application interactive
- How to deploy an application to a remote server (using Heroku as an example)
What is Dash?
Dash is an open-source framework for building data visualization interfaces. …

Leading data visualization tools to convey complex information
A person perceives 90% of information through sight. Clear visualization makes it easier to convey complex information. And what could be more confusing and more complicated than the stock and securities market?
Trading platforms, market forecasting agencies create tons of web-based tools for traders and analysts to interact with datasets. Technical progress is their unconditional assistant. Financial data can be visualized in various ways depending on the purpose. Let’s look at the outstanding JavaScript tools in data visualization capabilities.

CompressAI is an open-source library and platform for evaluating data compression models
The tool is based on the PyTorch deep learning framework. The task of data compression is to minimize the size of the data and at the same time preserve information as much as possible.
More about the library
Currently, CompressAI provides:
- Custom operations, layers, and neural network models for data compression;
- Part of the functionality from the official TensorFlow library for compression;
- Pretrained end-to-end compression models for image compression tasks;
- Scripts for evaluating and comparing trained models with classical methods of compressing photo and video data
The current version of the library does not support multi-GPU training. …
DATA SCIENCE
Detailed comparison of Python and R languages for use in Data Science
Python and R have long been the standard for Data Science. The essence of their opposition is that both languages are great for working with statistics. While Python has clear syntax and a large number of libraries, the R language was developed specifically for the statistician, and therefore is equipped with high-quality data visualization. SQL stands out — because if the data is already in tables, then it’s more luck than a reason for frustration — and Scala — mainly due to the fact that the most popular distributed data processing framework Spark is written in it.

How do the hearts of deep fakes beat? A new approach for deep fake detection via interpreting residuals with biological signals
Researchers at Binghampton University and Intel Corporation have developed a model that recognizes deepfakes by predicting heartbeats. The classifier uses photoplethysmogram data to recognize fake videos. An important assumption in the model is that it learns to recognize deepfakes that have been generated using a set of publicly available architectures. This imposes restrictions on the use of the model in real applications.
The approach detects fake videos with an accuracy of 97.27% and a generative model of deepfakes with an accuracy of 93.39%.

Objectron is a new SOTA dataset, recently presented by Google AI, which intended to improve 3D object recognition in videos. The dataset contains 15 thousand short video clips, each containing annotation of 3D boundaries of objects. The dataset contains both real clips and synthetic ones, that is, generated based on real ones.
What is the problem
The dataset is designed to facilitate the process of training models for 3D objects on 2D image and video data.
While 2D prediction only provides 2D bounding boxes, by extending prediction to 3D, one can capture an object’s size, position, and orientation in the world, leading to a…
PRODUCTIVITY
Productivity is about doing less, rather than doing more.
Do you do all the things time-management gurus tell you to but still end up less productive than you thought you would? There are several secrets that not everyone will tell you about. I will touch on 4 of the ones that stood out to me.
After an immense amount of research on the world’s most productive people, it becomes evident that they define productivity differently. It’s not about doing more, not about stuffing your schedule to the brim, not about getting more things done. …
