Classification of Signals01:30

Classification of Signals

1.5K
In signal processing, signals are classified based on various characteristics: continuous-time versus discrete-time, periodic versus aperiodic, analog versus digital, and causal versus noncausal. Each category highlights distinct properties crucial for understanding and manipulating signals.
A continuous-time signal holds a value at every instant in time, representing information seamlessly. In contrast, a discrete-time signal holds values only at specific moments, often denoted as x(n), where...

Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:

Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Aggregates Classification01:29

Aggregates Classification

1.1K
Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...

Area of Science:

  • Artificial Intelligence
  • Machine Learning
  • Optimization Algorithms

Background:

  • Complex data streams present challenges for neural networks due to dynamism and distributional shifts.
  • Frequent retraining is often required to maintain accuracy, impacting efficiency.
  • Existing optimization methods struggle with real-time adaptation to evolving data characteristics.

Purpose of the Study:

  • To propose an intelligent incremental learning framework for real-time hyperparameter optimization in neural networks.
  • To develop a Dynamic Grasshopper Optimization Algorithm (DGOA) for adaptive learning on data streams.
  • To enhance classification accuracy and efficiency in dynamic environments without constant retraining.

Main Methods:

  • Integration of a Dynamic Grasshopper Optimization Algorithm (DGOA) with a Multilayer Perceptron (MLP) neural network.
  • Utilizing DGOA's dynamic parameter control and online swarm reconfiguration for autonomous adaptation.
  • Incremental tuning of hyperparameters like learning rate and momentum for continuous learning.

Main Results:

  • The DGOA-based MLP achieved 89.5% classification accuracy on the Australian electricity market dataset.
  • Outperformed Grid Search, Random Search, PSO, GA, ACO, and standard GOA in classification accuracy.
  • Demonstrated superior efficiency with reduced computational time (120s), faster convergence (30 iterations), and lowest final loss (0.21).

Conclusions:

  • The proposed DGOA framework offers a fully online, swarm-intelligence-driven hyperparameter optimization strategy for big data streams.
  • This approach significantly improves accuracy, generalization, and computational efficiency compared to conventional methods.
  • The system effectively handles continuous distributional shifts in data streams, enabling robust and adaptive classification.
