Synthetic Biology

4.4K
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

How Data are Classified: Categorical Data

29.2K
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...

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:

Aggregates Classification

1.0K
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...

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,

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...

    • Machine Learning
    • Computer Science
    • Data Science

    Background:

    • Self-labeled techniques are semi-supervised classification methods that leverage limited labeled data by progressively classifying unlabeled data.
    • Existing methods, often based on boosting, face limitations due to sparse and scattered labeled data distributions.
    • A significant challenge in semi-supervised learning is the scarcity and uneven distribution of labeled examples.

    Purpose of the Study:

    • To propose a novel framework, synthetic examples generation for self-labeled semi-supervised classification, to improve classification performance.
    • To address the limitations of existing self-labeled methods by augmenting the available labeled data.
    • To enhance the robustness and accuracy of semi-supervised classification models in data-scarce scenarios.

    Main Methods:

    • A framework is proposed that generates synthetic labeled data using an oversampling technique and a positioning adjustment model.
    • The generated synthetic data, referencing both labeled and unlabeled examples, is integrated into the core stages of the self-labeling process.
    • The framework enhances classifier diversity, addresses data distribution issues, and is adaptable to various self-labeled methods.

    Main Results:

    • Empirical studies demonstrated that the proposed framework significantly improves the classification capabilities of four recent self-labeled methods.
    • The framework showed enhanced performance across a large number of diverse datasets, indicating its generalizability.
    • The integration of synthetic data led to improved classifier diversity and better fulfillment of labeled data distribution.

    Conclusions:

    • The synthetic examples generation framework offers a significant advancement for self-labeled semi-supervised classification.
    • This approach effectively overcomes the limitations posed by sparse and scattered labeled data.
    • The proposed method provides a versatile and impactful solution for improving machine learning model performance in data-limited settings.
