🥁🥁Undouble - Python library for detecting duplicate images using hash functions
Finding identical or similar photos manually is a long and tedious task. ITS can not be solved simply by comparing the size and file name, because. photos are taken from different sources (mobile devices, social networking applications, etc.), which results in differences in these attributes and creates differences in resolution, scaling, compression, and brightness. Hash functions are ideal for detecting identical and similar photos due to their resistance to minor changes. This idea is the basis of Undouble - the Python library that works using a multi-stage image preprocessing process (grayscale, normalization and scaling), image hash calculation, and image grouping. Threshold 0 will group images with identical image hash. The results can be easily examined using the plotting function, and the images can be moved using the move function. When moving images, the image from the group with the highest resolution is copied, and all other images are moved to the "undouble" subdirectory.
To try this open source library (https://github.com/erdogant/undouble), you first need to install it: pip install undouble, then import the package into your project: from undouble import Undouble. Then, by setting the hash method and hash size, duplicates can be detected using undouble. In this case, the following steps are performed: recursively reading all images from the directory with the specified extensions, computing the hash, and grouping similar images.

😜How to create an exe-file from a py-noscript
Although you can run a Python noscript in a terminal or text editor, sometimes you need to hide all the code in a py file by wrapping it inside an executable (.exe) file. For example, to schedule a job that runs an executable at a specific time. This can be done in 2 ways:
• via the GUI of the auto-py-to-exe package (https://pypi.org/project/auto-py-to-exe/), which must first be installed via pip install auto-py-to-exe, then run and follow 4 steps in sequence.
• in the terminal with the PyInstaller library, which should also be installed first: pip install pyinstaller, and then go to the directory with the desired py file and create an executable based on it using the pyinstaller --onefile name_of_noscript.py command
In fact, the first method is a visualization of the 2nd in a visual GUI. And those who work with the CLI interface can immediately use PyInstaller without any additional wrappers.

😜Neural networks for selfies on Google Pixel 6: accurate alpha matting in portrait mode
Matting an image is the process of extracting a precise alpha mask that separates the foreground and background objects of an image. This is not only necessary for professional designers when designing advertising photos, but has also become a popular entertainment for smartphone users. Send friends a selfie with the Eiffel Tower in the background while in a room with a grandmother's carpet? Easy with Google Pixel 6: a convolutional neural network from a sequence of encoder-decoder blocks to gradually evaluate high-quality alpha matting will preserve all the details, including fine hairs.
The input RGB image is combined with a coarse alpha matte (generated with a low resolution people segmenter) which is passed as input to the network. The new Portrait Matting model uses the MobileNetV3 backbone and a shallow decoder with few layers to first predict the low resolution advanced alpha mask. Then a shallow codec and a series of residual blocks are applied to process the high resolution image and the refined alpha mask from the previous step. The shallow codec relies more on lower level functions than the previous MobileNetV3 backbone, focusing on high resolution structural functions to predict the final transparency values for each pixel. This way the model can refine the original foreground alpha mask and accurately extract very fine details. This neural network architecture works effectively on Pixel 6 using Tensorflow Lite. The ML model also uses a variety of training datasets that cover a wide range of skin tones and hairstyles.

🍏Clustimage - Python library for image clustering
Unsupervised clustering in image recognition is a multi-step process. It includes preprocessing, feature extraction, similarity clustering, and estimation of the optimal number of clusters using a quality measure. All of these steps are implemented in the Clustimage Python package, which takes only paths or raw pixel values as input.
The goal of clustimage is to detect natural groups or clusters of images using the ilhouette, dbindex and their derivatives methods, in combination with clustering methods (agglomerative, kmeans, dbscan and hdbscan). Clustimage helps you determine the most robust clustering by efficiently searching by parameter and evaluating clusters. In addition to image clustering, the model can also be used to find the most similar images for a new invisible sample.
To try this open source library (https://github.com/erdogant/clustimage), you first need to install it: pip install clustimage, then import the package into your project: from clustimage import Clustimage.

🔥Hide a spicy photo from strangers? Easy with nudity detection API
Python program by DeepAI (https://deepai.org/machine-learning-model/nsfw-detector)
evaluates the image and estimates the likelihood that it covers areas of the human body that are usually found under clothing. The nudity check is a dynamic label, a certainty algorithm, or a false percentage. The user can set a different threshold in their app for what it considers to be nudity, and the image detection algorithm will return the percentage chance that the image contains natural content. This ML system is applicable not only to photos, but also to videos: neural networks analyze the video stream and give probabilistic feedback on the “adultness” of consumption.

😎3 Face Recognition ML Services APIs: Choose What You Need
• IBM Watson Visual Recognition API for identifying scenes, objects, and faces in images uploaded to the service. It can process unstructured data in a large volume and is suitable as a decision support system. But it is expensive to maintain and does not process structured data directly. The facial recognition method does not support general biometric recognition, and the maximum image size is 10 MB with a minimum recommended density of 32x32 ppi. Suitable for image classification using built-in classifiers, allows you to create your own classifiers and train ML models. https://www.ibm.com/watson
• Kairos Face Recognition API allows developers of ML applications to add face recognition capabilities to their applications by writing just a few lines of code. The Kairos Face Recognition API shows high accuracy in real-life scenarios and performs well in low light conditions as well as partial face hiding. Applies an ethical approach to identifying individuals, taking into account diversity. It is an extensible tool: users can apply additional intelligence to work with video and photos in the real world. Suitable for working with large volumes of images and ensures confidentiality through the secure storage of collected data and regular audits. However, it only supports BMP, JPG, and PNG file types, GIF files are not supported. Slightly slower in operation than the AWS API. https://www.kairos.com/docs/getting-started-with-kairos-face-recognition
• Microsoft Computer Vision API in Azure gives developers access to advanced image processing algorithms. Once an image is loaded or its URL is specified, Microsoft Computer Vision algorithms analyze its visual content in various ways based on the user's choice. An added benefit of this fast API is visual guides, tutorials, and examples. A high SLA guarantees at least 99.9% availability. Through tight integration with other Microsoft Azure cloud services, APIs can be packaged into a complete solution. But if the transaction per second limit is exceeded, the response time will be reduced to the agreed limit. The pricing model is demand-driven, so the service can become expensive if the number of requests spikes. The Microsoft Computer Vision API is great for classifying images with objects, creatures, scenery, and activities, including their identification, categorization, and image tagging. Supports face, mood, age and scene recognition, optical character recognition to detect text content in images. Also provides intelligent photo management and moderated content display restriction. https://azure.microsoft.com/en-us/services/cognitive-services/computer-vision/

👍🏻Sentiment analysis in social networks in Python with VADER without developing an ML model
Not every classification problem needs machine learning models: sometimes even simple approaches can give excellent results. For example, VADER (Valence Aware Dictionary and sEntiment Reasoner) is a vocabulary and rule based sentiment analysis model. The project source code is available on Github under the MIT license: https://github.com/cjhutto/vaderSentiment
VADER can efficiently handle dictionaries, abbreviations, capital letters, repetitive punctuation marks, emoticons (😢 , 😃 , 😭, etc.), etc., which are commonly used in social networks to express sentiment, making it an excellent text sentiment tool. The advantage of VADER is that it evaluates the mood of any text without prior training of ML models. The result generated by VADER is a dictionary of 4 keys neg, neu, pos and components (compound):
• neg, neu and pos mean negative, neutral and positive respectively. Their sum must be equal to 1 or close to it in a floating point operation.
• Compound corresponds to the sum of the valency scores of each word in the lexicon and determines the degree of mood, and not the actual value, unlike the previous ones. Its value ranges from -1 (the strongest negative mood) to +1 (the strongest positive mood). The use of a composite score may be sufficient to determine the main tone of the text. Compound ≥ 0.05 for positive mood, compound ≤ -0.05 for negative mood, compound ranges from -0.05 to 0.05 for neutral mood

💥Fusion plasma control with DL
To solve the global crisis, find sources of clean, limitless energy. For example, nuclear fusion, which powers the stars in the universe. On earth, atomic batteries can be used for this, breaking and fusing them under extreme conditions in a tokamak device - a vacuum surrounded by magnetic coils. In it the plasma radiation is hotter than the core of the Sun. The norm of the device in the operating mode is very difficult: the control system must coordinate many magnetic current coils and the voltage on them is several times less in order to achieve that the plasma never touches the walls of the vessel, which can lead to heat loss and, possibly, loss. Deep reinforcement learning has been successfully applied to this problem to create controllers that maintain plasma stability and stable control of various shapes.
Existing control systems for plasma complications and requiring rare control for each of the subsequent magnetic coils. Each controller uses algorithms to evaluate plasma properties in real time and measure magnet voltages. The architecture from the renowned Deep Mind AI Center and the Swiss Center for Plasma Research uses a single neural network to control all coils simultaneously, automatically judging which voltages are best for building plasma, especially with sensors.

🤜🏻ML to protect against DDos attacks
Machine learning algorithms are actively used in cybersecurity, for example, to identify atypical user behavior due to unauthorized access. ML can also be used to protect against DDOS attacks. The goal of a DDoS attack is to disrupt an organization by flooding a network, Internet-connected service, or technical infrastructure surrounding the target with unwanted traffic. The amount of traffic directed to the target can severely limit or disable availability.
DDoS attacks use Internet-connected devices that have already been compromised by malware. An attacker exploits existing vulnerabilities in dozens, hundreds, thousands, or even millions of devices to gain remote control. Thanks to the ubiquity of IoT devices, when even a home refrigerator goes online, protection against DDOS attacks is relevant for both businesses and private households.
A 2017 Kaspersky Lab survey found that the cost of sustaining a DDoS attack for small and medium businesses was $120,000. For large enterprises, this figure has risen to $2 million. And a 2018 study estimated the cost of downtime for a large organization to range from $300,000 to $540,000. In the US, the average global cost of a data breach was $8.46 million, according to a 2020 IBM report.
Using ML, you can build a binary classification model that would mitigate the impact of a DDoS attack on an organization's activities by correctly distinguishing safe traffic from malicious traffic. Here it is necessary to reduce the rate at which the ML model incorrectly identified safe traffic as malicious, as well as mitigate the consequences of a DDoS attack by correctly identifying malicious traffic with a probability of at least 90%.

📝MLOps basics: 5 formats for transferring ML models
For ML systems, portability between different stages of the life cycle, from development to deployment in production, is important. For example, a Data Scientist writes code in notebooks like Jupyter Notebook or Google Colab. When porting this code to a production environment, it should be converted to a lightweight interchange format, compressed and serialized, that is independent of the development language. These formats are as follows:
• Pickle is a binary version of a Python object for serialization and deserialization of its structure, ie. converting a hierarchy of Python objects to a stream of bytes and vice versa;
• ONNX (Open Neural Network Exchange) is an open source format for ML models that provides a common set of operators and a universal file format for various platforms and tools. The ONNX format describes a computation graph (input, output, and operations) and is self-contained. It is deep learning focused, supported by Microsoft and Facebook, and works great with TensorFlow and PyTorch.
• PMML (Predictive Model Markup Language) is an XML-based predictive model exchange format that allows you to develop a model in one system for one application and deploy it to another using another application by passing an XML configuration file.
• PFA (Portable Format for Analytics) is a standard for statistical models and data transformation engines that is easily portable between different systems and models. Pre-processing and post-processing functions can be chained together and built into complex workflows. A PFA can be a simple raw data transformation or a complex set of parallel data mining models with a JSON or YAML configuration file.
• NNEF (Neural Network Exchange Format) is a format that facilitates the process of deploying machine learning, allowing you to use a set of neural network training tools for applications on various devices and platforms.
There are also framework-specific formats, such as POJO/MOJO for the H2O AutoML platform and Spark MLWritable for Apache Spark.

🙌🏻Generation of 3D scenes from 2D photos with NVIDIA's NeRF
Inverse rendering has long used AI to approximate the behavior of light in the real world, allowing a 3D scene to be reconstructed from multiple 2D images taken from different angles. The NVIDIA research team has developed an approach that solves this problem almost instantly by combining ultra-fast neural network training and fast rendering.
NVIDIA has taken this approach to a popular new technology called Neural Radiation Fields, or NeRF. The result, dubbed Instant NeRF, is the fastest NeRF technology to date, achieving over 1000x speedup in some cases. It only takes a few seconds for the model to learn from a few dozen still photos - plus the camera angles they were taken from - and then it can render the resulting 3D scene in tens of milliseconds.
NeRFs use neural networks to represent and render realistic 3D scenes based on an input collection of 2D images. Collecting data for NeRF transmission is reminiscent of the work of a photographer on the red carpet: the neural network needs several dozen images taken from different points of the scene, as well as the position of the camera of each of them.
Typically, creating a 3D scene using traditional methods takes several hours or more, depending on the complexity and resolution of the rendering. Bringing AI into the picture speeds things up. Early NeRF models rendered crisp, artifact-free scenes in minutes, but took hours to learn. Instant NeRF reduces rendering time by several orders of magnitude. It is based on multi-resolution hash mesh encoding that is optimized to run efficiently on NVIDIA GPUs. This way you can achieve high-quality results using a fast and small neural network.
The model was developed using the NVIDIA CUDA toolkit and the Tiny CUDA neural network library. Due to its lightness, the neural network can be trained and run on a single NVIDIA GPU - it runs fastest on cards with NVIDIA Tensor Cores.
This technology will be useful for training robots and self-driving cars so that they can understand the size and shape of objects in the real world by capturing 2D images or video recordings of them. It can also be used in architecture and entertainment to quickly create digital representations of real environments that creators can modify and use.
