Abstract
Deep neural networks (DNNs) have achieved significant performance improvement in image classification tasks.A DNN utilizes an enormous number of trainable parameters and non-linear functions to learn a mapping from a set of input images to a set of target classes. However, the increasing number of parameters, called the overparameterization problem, can create major challenges in implementation of these models on resource limited devices and can encourage overfitting of the model. Pruning less important trainable parameters in DNNs is one of the major established methods to defeat the above challenges. Pruning methods are also applicable on small models by design to further reduce their size. This thesis proposes the concept of energy models for pruning convolutional filters and hidden units with corresponding incoming and outgoing connections and bias terms for image classification tasks. Specifically, two energy models, namely EPruning and IPruning, are proposed. The first approach uses the Hamiltonian of a given DNN to form an energy loss minimization problem. The loss function is defined based on the difference between the energy of target class and the closest energy of the competitive classes. The second approach uses entropy of feature maps, Kullback–Leibler (KL) divergence between convolution filters in a layer, and activation level of hidden units to form an Ising energy-based minimization problem for detecting less important and redundant parameters in the network. Despite most pruning methods, which are based on defining a pruning threshold per layer, the proposed methods are data-driven and perform a network-wise pruning of the trainable parameters. We define pruning as searching for a sub-network of a given DNN, which has the lowest energy loss value based on a defined energy loss function. Since this is an NP-hard combinatorial optimization problem, a population-based global optimization framework is proposed to minimize the pruning objective functions. The proposed framework is evaluated on different flavors of DNNs (e.g. ResNets, AlexNet, and SqueezeNet) and datasets (e.g. CIFAR-10, CIFAR-100, and ImageNet) for image classification tasks.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
