La veille de la cybersécurité
We've seen AIs create music, pornography and art. The Estonian startup Yummy started off creating a meal-kit startup, but along the way created an AI that can create and adapt recipes based on your taste and dietary restrictions, complete with AI-generated images of what your dishes might look like. "Imagine a world where you would not have to spend years of your life on deciding what to eat, search for recipes, research nutritional information and health benefits, follow diets and do grocery shopping," says co-founder and CEO Martin Salo in an interview with TechCrunch. "Imagine we solve this complex problem on your behalf, based on your personal preferences -- and got it right every time." The co-founders of the company started Clean Kitchen together in Estonia back in 2020.
Android & IOs Apps for Learning Python
Python is a popular scripting programming language. It is used for a range of purposes, including web design, data analysis and science, visualization, machine learning, and more. Suitable for both Android and iOS devices, apps is a preferred choice for many programmers for learning python in the United States and beyond. I have done some research for you to identify and recommend some of the best apps for learning Python. There is no dearth of resources, so my goal was to identify the top ones with great reviews and a proven track record of effectiveness.
Top Machine Learning Model Deployment Tools For 2022
In the field of technology, machine learning is nothing new. The capacity to automate channels and increase company process flexibility brought about a revolutionary change for numerous industries. The machine learning lifecycle governs many aspects of developing and deploying trained model APIs in the production environment. Model deployment, which differs from the creation of ML models in that it has a steeper learning curve for beginners, has proven to be one of the most significant challenges in data science. Model deployment refers to integrating a machine learning model that accepts an input and delivers an output to make helpful business decisions based on data into an already-existing production environment.
Machine Learning Approach for Predicting Students Academic Performance and Study Strategies based on their Motivation
Orji, Fidelia A., Vassileva, Julita
This research aims to develop machine learning models for students academic performance and study strategies prediction which could be generalized to all courses in higher education. Key learning attributes (intrinsic, extrinsic, autonomy, relatedness, competence, and self-esteem) essential for students learning process were used in building the models. Determining the broad effect of these attributes on students' academic performance and study strategy is the center of our interest. To investigate this, we used Scikit-learn in python to build five machine learning models (Decision Tree, K-Nearest Neighbour, Random Forest, Linear/Logistic Regression, and Support Vector Machine) for both regression and classification tasks to perform our analysis. The models were trained, evaluated, and tested for accuracy using 924 university dentistry students' data collected by Chilean authors through quantitative research design. A comparative analysis of the models revealed that the tree-based models such as the random forest (with prediction accuracy of 94.9%) and decision tree show the best results compared to the linear, support vector, and k-nearest neighbours. The models built in this research can be used in predicting student performance and study strategy so that appropriate interventions could be implemented to improve student learning progress. Thus, incorporating strategies that could improve diverse student learning attributes in the design of online educational systems may increase the likelihood of students continuing with their learning tasks as required. Moreover, the results show that the attributes could be modelled together and used to adapt/personalize the learning process.
POGD: Gradient Descent with New Stochastic Rules
Han, Feihu, Xing, Sida, Khoo, Sui Yang
Gradient descant is a popular optimization in neural networks. Nowadays, neural network has attracted much attention in any fields, there are many different types of the neural networks that has already been developed(Haykin, 2009). The convolutional neural networks is very popular in the classification field(Huang et al., 2017), even though it is a kind of the feedforward neural network(Haykin, 2009). In recent years, the structure of convolutional neural network has been rapidly improved(Smith and Topin, 2016). However, many improvements develop the structural algorithm of convolutional neural network, but not much improve it from optimization.
DyFEn: Agent-Based Fee Setting in Payment Channel Networks
Asgari, Kiana, Mohammadian, Aida Afshar, Tefagh, Mojtaba
In recent years, with the development of easy to use learning environments, implementing and reproducible benchmarking of reinforcement learning algorithms has been largely accelerated by utilizing these frameworks. In this article, we introduce the Dynamic Fee learning Environment (DyFEn), an open-source real-world financial network model. It can provide a testbed for evaluating different reinforcement learning techniques. To illustrate the promise of DyFEn, we present a challenging problem which is a simultaneous multi-channel dynamic fee setting for off-chain payment channels. This problem is well-known in the Bitcoin Lightning Network and has no effective solutions. Specifically, we report the empirical results of several commonly used deep reinforcement learning methods on this dynamic fee setting task as a baseline for further experiments. To the best of our knowledge, this work proposes the first virtual learning environment based on a simulation of blockchain and distributed ledger technologies, unlike many others which are based on physics simulations or game platforms.
Emergent Communication: Generalization and Overfitting in Lewis Games
Rita, Mathieu, Tallec, Corentin, Michel, Paul, Grill, Jean-Bastien, Pietquin, Olivier, Dupoux, Emmanuel, Strub, Florian
Lewis signaling games are a class of simple communication games for simulating the emergence of language. In these games, two agents must agree on a communication protocol in order to solve a cooperative task. Previous work has shown that agents trained to play this game with reinforcement learning tend to develop languages that display undesirable properties from a linguistic point of view (lack of generalization, lack of compositionality, etc). In this paper, we aim to provide better understanding of this phenomenon by analytically studying the learning problem in Lewis games. As a core contribution, we demonstrate that the standard objective in Lewis games can be decomposed in two components: a co-adaptation loss and an information loss. This decomposition enables us to surface two potential sources of overfitting, which we show may undermine the emergence of a structured communication protocol. In particular, when we control for overfitting on the co-adaptation loss, we recover desired properties in the emergent languages: they are more compositional and generalize better.
The Influence of Multiple Classes on Learning Online Classifiers from Imbalanced and Concept Drifting Data Streams
Lipska, Agnieszka, Stefanowski, Jerzy
This work is aimed at the experimental studying the influence of local data characteristics and drifts on the difficulties of learning various online classifiers from multi-class imbalanced data streams. Firstly we present a categorization of these data factors and drifts in the context of imbalanced streams, then we introduce the generators of synthetic streams that model these factors and drifts. The results of many experiments with synthetically generated data streams have shown a much greater role of the overlapping between many minority classes (the type of borderline examples) than for streams with one minority class. The presence of rare examples in the stream is the most difficult single factor. The local drift of splitting minority classes is the third influential factor. Unlike binary streams, the specialized UOB and OOB classifiers perform well enough for even high imbalance ratios. The most challenging for all classifiers are complex scenarios integrating the drifts of the identified factors simultaneously, which worsen the evaluation measures in the case of a several minority classes stronger than for binary ones. This is an extended version of the short paper presented at LIDTA'2022 workshop at ECMLPKDD2022.
