This document summarizes different types of supervised learning networks including perceptrons, Adaline networks, and backpropagation networks. It provides details on their architectures, training algorithms, and how they work. The key points are:
- Perceptrons are single layer feedforward networks that use the perceptron learning rule to update weights and converge on the correct output.
- Adaline networks have a single linear output unit and use the delta rule to minimize mean squared error and adjust weights between the input and output units.
- Backpropagation networks can have multiple hidden layers and use gradient descent to calculate and propagate error back through the network to update weights between layers and improve classification of input patterns.

An Artificial Neural Network (ANN) is a computational model inspired by the structure and functioning of the human brain's neural networks. It consists of interconnected nodes, often referred to as neurons or units, organized in layers. These layers typically include an input layer, one or more hidden layers, and an output layer.
Web spam classification using supervised artificial neural network algorithmsaciijournal
Due to the rapid growth in technology employed by the spammers, there is a need of classifiers that are more efficient, generic and highly adaptive. Neural Network based technologies have high ability of adaption as well as generalization. As per our knowledge, very little work has been done in this field using neural network. We present this paper to fill this gap. This paper evaluates performance of three supervised learning algorithms of artificial neural network by creating classifiers for the complex problem of latest web spam pattern classification. These algorithms are Conjugate Gradient algorithm, Resilient Backpropagation learning, and Levenberg-Marquardt algorithm.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

Embracing GenAI - A Strategic ImperativePeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

applied on net input
11. Perceptron rule convergence theorem
• If there is weight vector W such that

for any starting vector w1, the perceptron learning rule will converge
to a weight vector that gives correct response for all training patterns ,
in finite number of steps.

CLASS
15. Perceptron Training Algorithm for multiple output classes
Step 0: Initialize weights, bias and learning rate suitably

Step 2: Perform steps 3-5 for each bipolar or binary training vector
pair s:t

input is calculated as
16. Perceptron Training Algorithm for multiple output classes
• Activations applied over the net input are:
• Step 5: make adjustments in weights and
Bias for j=1 to m and i=1 to n.
17. Perceptron Training Algorithm for multiple output classes
• Step 6 : test for stopping condition , if no change in weights then stop
the training process else start again from step 2.
18. Adaptive Linear Neuron (Adaline)
• A network with single linear unit is called Adaline
• Units with linear activation functions are called linear units.
• Input output relation is linear.
• Uses Bipolar activation.
• Adaline network has only one output unit
• Weights and Bias(activation =1) between input and output are
adjustable.
• Adaline uses delta rule/least mean square rule/ Widrow-Hoff rule.
• delta rule Minimizes mean squared error (activation and target value)
19. Delta rule
• Derived from gradient descent method.
• Delta rule updates the weights between the connections so as to
minimize the difference between the net input to the output unit and
the target value .
• Minimize the errors of the training patterns by reducing for each
pattern one at a time.
= learning rate
• X= vector of activation of input unit
