** 1. Qauv Pruning **

Tus qauv pruning cuam tshuam nrog tshem tawm qhov hnyav thiab kev sib txuas ntawm tus qauv AI, txo nws qhov loj me thiab cov kev xav tau ntawm kev suav. Cov txheej txheem no tuaj yeem siv rau ob qho tib si neural networks thiab cov ntoo txiav txim siab.

`` python import taws import torch.nn as nn

chav ModelPruning(nn.Module): def init(self): super(ModelPruning, tus kheej).init() self.fc1 = nn.Linear(784, 128) self.fc2 = nn.Linear(128, 10)

def forward(tus kheej, x):
    x = torch.relu(self.fc1(x))
    x = self.fc2(x)
    rov x

qauv = ModelPruning() pruned_model = torch.nn.utils.prune_l1_unstructured(model, ' nyhav', 0.1)

### ** 2. Kev Paub Txog Distillation **

Kev paub txog distillation suav nrog kev hloov kev paub los ntawm tus qauv loj, nyuaj AI mus rau ib qho me me, yooj yim dua. Cov txheej txheem no tuaj yeem siv los txo qhov loj me thiab cov kev xav tau ntawm cov qauv AI.

`` python
import taws
import torch.nn as nn

chav KnowledgeDistillation(nn.Module):
    def __init__(self):
        super(KnowledgeDistillation, tus kheej).__init__()
        self.fc1 = nn.Linear(784, 128)
        self.fc2 = nn.Linear(128, 10)

    def forward(tus kheej, x):
        x = torch.relu(self.fc1(x))
        x = self.fc2(x)
        rov x

xib fwb_model = ModelPruning()
student_model = KnowledgeDistillation()

** 3. Quantization **

Quantization suav nrog txo qhov tseeb ntawm AI qauv hnyav thiab kev ua haujlwm, txo cov kev xav tau ntawm tus qauv AI.

`` python import taws import torch.nn as nn

chav kawm Quantization(nn.Module): def init(self): super(Quantization, tus kheej).init() self.fc1 = nn.Linear(784, 128) self.fc2 = nn.Linear(128, 10)

def forward(tus kheej, x):
    x = torch.relu(self.fc1(x))
    x = self.fc2(x)
    rov x

qauv = ModelPruning() quantized_model = torch.quantization.quantize_dynamic(model, {torch.nn.Linear}, dtype=torch.qint8)
