The Transformer Model

#artificialintelligence

We have already familiarized ourselves with the concept of self-attention as implemented by the Transformer attention mechanism for neural machine translation. We will now be shifting our focus on the details of the Transformer architecture itself, to discover how self-attention can be implemented without relying on the use of recurrence and convolutions. In this tutorial, you will discover the network architecture of the Transformer model. The Transformer Model Photo by Samule Sun, some rights reserved. The Transformer architecture follows an encoder-decoder structure, but does not rely on recurrence and convolutions in order to generate an output.


Multi-Task Learning on Networks

arXiv.org Artificial Intelligence

The multi-task learning (MTL) paradigm can be traced back to an early paper of Caruana (1997) in which it was argued that data from multiple tasks can be used with the aim to obtain a better performance over learning each task independently. A solution of MTL with conflicting objectives requires modelling the trade-off among them which is generally beyond what a straight linear combination can achieve. A theoretically principled and computationally effective strategy is finding solutions which are not dominated by others as it is addressed in the Pareto analysis. Multi-objective optimization problems arising in the multi-task learning context have specific features and require adhoc methods. The analysis of these features and the proposal of a new computational approach represent the focus of this work. Multi-objective evolutionary algorithms (MOEAs) can easily include the concept of dominance and therefore the Pareto analysis. The major drawback of MOEAs is a low sample efficiency with respect to function evaluations. The key reason for this drawback is that most of the evolutionary approaches do not use models for approximating the objective function. Bayesian Optimization takes a radically different approach based on a surrogate model, such as a Gaussian Process. In this thesis the solutions in the Input Space are represented as probability distributions encapsulating the knowledge contained in the function evaluations. In this space of probability distributions, endowed with the metric given by the Wasserstein distance, a new algorithm MOEA/WST can be designed in which the model is not directly on the objective function but in an intermediate Information Space where the objects from the input space are mapped into histograms. Computational results show that the sample efficiency and the quality of the Pareto set provided by MOEA/WST are significantly better than in the standard MOEA.


An AI-based Solution for Enhancing Delivery of Digital Learning for Future Teachers

arXiv.org Artificial Intelligence

However, up until the COVID-19 pandemic caused a seismic shift in the education sector, few educational institutions had fully developed digital learning models in place and adoption of digital models was ad-hoc or only partially integrated alongside traditional teaching modes [1]. In the wake of the disruptive impact of the pandemic, the education sector and more importantly educators have had to move rapidly to take up digital solutions to continue delivering learning. At the most rudimentary level, this has meant moving to online teaching through platforms such as Zoom, Google, Teams and Interactive Whiteboards and delivering pre-recorded educational materials via Learning Management Systems (e.g., Echo). Digital learning is now simply part of the education landscape both in the traditional education sector as well as within the context of corporate and workplace learning. A key challenge future teachers face when delivering educational content via digital learning is to be able to assess what the learner knows and understands, the depths of that knowledge and understanding and any gaps in that learning. Assessment also occurs in the context of the cohort and relevant band or level of learning. The Teachers Guide to Assessment produced by the Australian Capital Territory Government [2] identified that teachers and learning designers were particularly challenged by the assessment process, and that new technologies have the potential to transform existing digital teaching and learning practices through refined information gathering and the ability to enhance the nature of learner feedback. Artificial Intelligence (AI) is part of the next generation of digital learning, enabling educators to create learning content, stream content to suit individual learner needs and access and in turn respond to data based on learner performance and feedback [3]. AI has the capacity to provide significant benefits to teachers to deliver nuanced and personalised experiences to learners.

Python is a general-purpose, object-oriented, high-level programming language. Python is a multi-paradigm language, which means that it supports many programming approaches. Along with procedural and functional programming styles Python is a widely used, general-purpose programming language, but it has some limitations. Because Python is an interpreted, dynamically typed language Python is a general programming language used widely across many industries and platforms. One common use of Python is scripting, which means automating tasks. Python is a popular language that is used across many industries and in many programming disciplines. DevOps engineers use Python to script website. Python has a simple syntax that makes it an excellent programming language for a beginner to learn. To learn Python on your own, you first must become familiar Machine learning describes systems that make predictions using a model trained on real-world data. Machine learning is being applied to virtually every field today. That includes medical diagnoses, facial recognition, weather forecasts, image processing.


First to Launch Coding, Robotics Courses in Govt Schools, Goa Sets Example for All States

#artificialintelligence

In a move that aims to benefit 65,600 students and 540 teachers from government and government-aided schools in Goa, the State government in March this year implemented its novel and first of its kind in India โ€“ Coding and Robotics Education in Schools Scheme from the academic year 2021-22. The scheme aims to incorporate computational and design thinking abilities, as well as programming, into the Goa state board curriculum to prepare students to the needs of the digital world in the 21st century. It was introduced by Chief Minister Dr Pramod Sawant, who is also the Minister of Education. The State government is looking to make this sort of skill education (coding and problem solving skills) accessible to school-going children from all sections of society. This scheme is a collaborative effort of the Directorate of Technical Education (DTE), Directorate of Education, State Council Educational Research and Training (SCERT) and industry experts.


What is PyTorch? - PyImageSearch

By the end of this tutorial, you'll have a good introduction to the PyTorch library and be able to discuss the pros and cons of the library with other deep learning practitioners. To learn about the PyTorch deep learning library, just keep reading. PyTorch is an open source machine learning library that specializes in tensor computations, automatic differentiation, and GPU acceleration. For those reasons, PyTorch is one of the most popular deep learning libraries, competing with both Keras and TensorFlow for the prize of "most used" deep learning package: PyTorch tends to be especially popular among the research community due to its Pythonic nature and ease of extendability (i.e., implementing custom layer types, network architectures, etc.). In this tutorial, we'll discuss the basics of the PyTorch deep learning library.
