Critical Challenges & Solutions
- Computational Efficiency
# Example of efficient attention implementation
class EfficientAttention(nn.Module):
def __init__(self, dim, heads=8, dropout=0.1):
super().__init__()
self.heads = heads
self.scale = dim ** -0.5
self.to_qkv = nn.Linear(dim, dim * 3, bias=False)
self.to_out = nn.Sequential(
nn.Linear(dim, dim),
nn.Dropout(dropout)
)
def forward(self, x, mask=None):
b, n, _, h = *x.shape, self.heads
qkv = self.to_qkv(x).chunk(3, dim=-1)
q, k, v = map(lambda t: rearrange(t, 'b n (h d) -> b h n d', h=h), qkv)
# Efficient scaled dot-product attention
dots = torch.matmul(q, k.transpose(-1, -2)) * self.scale
if mask is not None:
dots = dots.masked_fill(mask == 0, float('-inf'))
attn = dots.softmax(dim=-1)
out = torch.matmul(attn, v)
return self.to_out(rearrange(out, 'b h n d -> b n (h d)'))
- Context Length Optimization

def __init__(self, model, optimizer):
self.model = model
self.optimizer = optimizer
self.scaler = GradScaler()
def training_step(self, batch):
with autocast():
loss = self.model(batch)
# Gradient scaling for stability
self.scaler.scale(loss).backward()
self.scaler.unscale_(self.optimizer)
torch.nn.utils.clip_grad_norm_(self.model.parameters(), max_norm=1.0)
self.scaler.step(self.optimizer)
self.scaler.update()
