Improving Translational Accuracy

13.7K
Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Generalization, Discrimination, and Extinction

1.2K
Generalization, discrimination, and extinction are key concepts in operant conditioning that influence how behaviors are learned and maintained.
Generalization occurs when a behavior reinforced in one context is performed in similar situations. For instance, a student who studies diligently for calculus and receives excellent grades might apply the same study habits to psychology and history, expecting similar results. Generalization shows how learning in one setting can influence behavior in...

Observational Learning01:12

Observational Learning

717
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Introduction to Learning01:18

Introduction to Learning

768
Learning is the process of acquiring knowledge or skills through practice or experience, leading to long-lasting behavioral changes. This acquisition occurs through interaction with the environment and requires practice or experience. For instance, mastering a skill such as surfing requires considerable practice and experience, highlighting the essential role of repeated interactions with the environment in learning.
In contrast to learned behaviors, unlearned behaviors such as crying, sexual...

Per-Unit Sequence Models

350
An ideal Y-Y transformer, grounded through neutral impedances, displays per-unit sequence networks akin to those of a single-phase ideal transformer when subjected to balanced positive- or negative-sequence currents. These currents do not produce neutral currents, and their associated voltage drops.
Zero-sequence currents, which are identical in magnitude and phase, generate a neutral current, resulting in voltage drops across the neutral impedance and the low-voltage winding. If the...

    Background:

    • Generalized zero-shot learning (GZSL) faces performance challenges when recognizing both seen and unseen classes.

    Purpose of the Study:

    • To propose an effective mechanism for GZSL and open-set recognition using a transfer-increment strategy.
    • To address the data missing problem and optimize generative model training for unseen classes.

    Main Methods:

    • A dual-knowledge-source generative model synthesizes virtual exemplars using local and global relational knowledge.
    • Two incremental training modes are designed to learn unseen classes directly from synthesized data.
    • The transfer-increment strategy integrates data generation and model training for GZSL.

    Main Results:

    • The proposed strategy significantly improves performance in conventional and GZSL tasks across five benchmark datasets.
    • The method effectively tackles the missing data problem by synthesizing virtual exemplars.
    • Incremental training modes enhance unseen class learning while reducing computational and storage requirements.

    Conclusions:

    • The transfer-increment strategy offers a simple yet effective solution for GZSL and open-set recognition.
    • The dual-knowledge-source generative model and incremental training modes are key to the performance gains.
    • This approach provides a computationally efficient and high-performing method for recognizing unseen classes.
