Multi-input and Multi-variable systems

Multi-input and Multi-variable systems

Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.

Machines: Problem Solving II

Machines: Problem Solving II

Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. Consider a lifting tong carrying a 100 kg load. It comprises movable sections DAF and CBG linked together with member AB.

Machines: Problem Solving I

A toggle clamp is a mechanical device commonly used for holding and clamping objects in various applications, such as woodworking, metalworking, and assembly operations. Consider a toggle clamp subjected to a force of 200 N at the handle. The vertical clamping force can be calculated, provided the dimensions of the toggle clamp are known.
The toggle clamp system is a machine structure consisting of movable, pin-connected multi-force members that form a stabilized system to transmit forces. The...

Associative Learning

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Summary

Three adaptive Ho-Kashyap (AHK) algorithms improve perceptron training. These methods adapt to form robust linear discriminant surfaces, with AHK III efficiently handling non-linearly separable data.

Area of Science:

Machine Learning
Artificial Intelligence
Pattern Recognition

Background:

Perceptron training algorithms are fundamental in machine learning for classification.
Gradient descent strategies offer adaptive approaches to optimize model training.
Existing methods like LMS and perceptron have limitations in handling complex data distributions.

Purpose of the Study:

To derive adaptive versions of the Ho-Kashyap perceptron training algorithm.
To enhance classification robustness and convergence speed for linear and non-linear problems.
To compare the performance of new adaptive Ho-Kashyap (AHK) algorithms against established methods.

Main Methods:

Development of three adaptive Ho-Kashyap (AHK) training algorithms based on gradient descent.
