Classification of Systems-I01:26

Classification of Systems-I

496
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,

How Data are Classified: Categorical Data

41.9K
A variable, usually notated by capital letters such as X and Y, is a characteristic or measurement that can be determined for each member of a population. Data are the actual values of variables. They may be numbers, or they may be words. Datum is a single value.
Data are classified based on whether they are measurable or not. Categorical data cannot be measured; instead, it can be divided into categories. For example, if Y denotes a person's party affiliation, some examples of Y include...

Classification of Signals

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...

Multi-input and Multi-variable systems

326
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.
In the absence of...

Aggregates Classification01:29

Aggregates Classification

887
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:

    • Machine Learning
    • Data Science
    • Computer Science

    Background:

    • Multilabel classification (MLC) algorithms leverage label correlations but require extensive labeled data, which is often scarce and expensive.
    • Existing MLC methods use centralized learning, demanding data transmission to a fusion center, posing challenges for distributed networks due to communication, processing, and privacy constraints.

    Purpose of the Study:

    • To address the limitations of centralized learning and data scarcity in MLC.
    • To propose novel distributed algorithms for semisupervised multilabel classification over networks.

    Main Methods:

    • Developed two distributed information-theoretic semisupervised multilabel learning (dITS²ML²) algorithms for linear and nonlinear MLC problems.
    • Designed a cost-sensitive objective function incorporating a novel label correlation term on anchor data.
    • Utilized a distributed matrix completion algorithm to decentralize the objective function and estimate model parameters by exchanging intermediate quantities.

    Main Results:

    • The proposed dITS²ML² algorithms enable adaptive estimation of model parameters without transmitting raw data, preserving privacy and reducing communication costs.
    • Convergence analysis confirmed the stability of the algorithms.
    • Simulations on real datasets demonstrated the effectiveness of the proposed methods for distributed MLC.

    Conclusions:

    • The novel dITS²ML² algorithms offer a viable solution for distributed semisupervised multilabel classification, overcoming challenges of data scarcity and decentralized data storage.
    • These methods provide an efficient and privacy-preserving approach for learning from distributed data in real-world applications.
