Force Classification01:22

Force Classification

1.2K
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

Classification of Leukocytes01:30

Classification of Leukocytes

1.9K
Leukocytes are classified into two groups based on the presence or absence of cytoplasmic granules. Granular leukocytes, which contain granules, belong to the myeloid lineage and are divided into three subtypes: neutrophils, eosinophils, and basophils. These cells are roughly spherical and characterized by the granules in their cytoplasm.
Neutrophils are the most abundant type of granular leukocytes, comprising 50-70% of all leukocytes. They feature small, evenly distributed granules and a...

Classification of Signals01:30

Classification of Signals

472
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...

Classification of Systems-II01:31

Classification of Systems-II

149
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 Data01:11

How Data are Classified: Categorical Data

33.1K
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...

Aggregates Classification01:29

Aggregates Classification

327
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
    • Computer Science

    Background:

    • Federated learning (FL) is crucial for representation learning (RL) but current models struggle to leverage client-specific data.
    • Most FL models aim for a single, identical model, neglecting individual client data characteristics.

    Purpose of the Study:

    • To introduce a federated discriminative RL (FDRL) model to enhance classification performance in FL.
    • To address the limitations of current FL models by utilizing data specificity between clients.

    Main Methods:

    • FDRL partitions client features into global and local subspaces for improved representation learning.
    • It trains shared submodels for federated communication and distinct submodels for local feature preservation.
    • A linear model combines these features for image classification, optimized iteratively between a central server and clients.

    Main Results:

    • FDRL effectively captures common features via global representation and preserves unique client features via local representation.
    • The model demonstrated more discriminative data representations compared to existing FL models.
    • Experimental results on public datasets showed superior federated image classification performance.

    Conclusions:

    • FDRL's subspace partitioning strategy significantly benefits federated image classification.
    • The model achieves state-of-the-art performance by effectively balancing global knowledge sharing and local data personalization.
