Reducing Line Loss

Reducing Line Loss

In a three-phase circuit, line loss is an indicator of energy dissipated as heat due to the resistance of transmission lines. To address this, incorporating transformers into the system—a step-up transformer at the source and a step-down transformer at the load—is a strategic solution. Two three-phase transformers are introduced to improve this.
With a step-up transformer at the source, the voltage is increased, thereby reducing the current in the transmission lines since power loss in...

Survival Tree

Survival Tree

Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Neural Circuits

Neural Circuits

Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

Neural Regulation

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Neuroplasticity

Neuroplasticity

Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

Downsampling

Downsampling

When considering a sampled sequence with zero values between sampling instants, one can replace it by taking every N-th value of the sequence. At these integer multiples of N, the original and sampled sequences coincide. This process, known as decimation, involves extracting every N-th sample from a sequence, thereby creating a more efficient sequence.
The Fourier transform of the decimated sequence reveals a combination of scaled and shifted versions of the original spectrum. This...

Background:

Pruning is a common technique to optimize convolutional neural networks (CNNs) for efficiency.
Existing pruning methods often overlook neuron correlations in the original feature space, leading to residual redundancy.

Purpose of the Study:

To develop a novel pruning strategy that addresses redundancy in CNNs.
To improve both the efficiency (speed) and accuracy of pruned neural networks.

Main Methods:

Proposed a redundancy-aware pruning method operating in an intermediate feature space.
Utilized orthogonal transformation to map layer inputs/outputs to this intermediate space, eliminating neuron correlations.
Evaluated and pruned neurons within this decorrelated intermediate space.

Main Results:

The proposed method significantly surpasses state-of-the-art pruning techniques in both efficiency and accuracy.
Achieved competitive performance with substantial speed-up (e.g., 3x for ResNet) and fewer floating-point operations compared to DenseNet.

Conclusions:

Pruning in an intermediate, decorrelated space is a more effective strategy for reducing network redundancy.
This approach offers a promising direction for developing highly efficient and accurate deep learning models.
