# Sparse Gradient Synaptic Plasticity
## 核心思想
实现真正稀疏且通用的梯度突触可塑性规则,避免手动推导梯度或牺牲在线能力。

## 实现
```python
import numpy as np
class SparseGradientPlasticity:
def __init__(self, n_pre, n_post, sparsity=0.1):
self.W = np.random.randn(n_post, n_pre) * 0.1
self.mask = np.random.rand(n_post, n_pre) < sparsity
self.W *= self.mask
self.eta = 0.01
def forward(self, x):
return self.W @ x
def update(self, pre, post, error):
dW = self.eta * np.outer(error * post, pre)
self.W += dW * self.mask
```

Playbook for creating and editing uCoz landing pages via MCP tools (`templates_tool`, `ftp_tool`, `modules_tool`). Use for tasks such as: "build a landing page", "update the homepage as a landing page", "create a promo page on the homepage", "add a lead form / menu / SEO to the homepage". Homepage: `page_list`, `page_get`; first publish — `page_update` with full `page_tmpl`; HTML edits after generation — `patch_template` (module_id=2, template_id=1), not `update_template`.

Interact with the Paperclip control plane API to manage tasks, coordinate with other agents, and follow company governance. Use when you need to check assignments, update task status, delegate work, post comments, set up or manage routines (recurring scheduled tasks), or call any Paperclip API endpoint. Do NOT use for the actual domain work itself (writing code, research, etc.) — only for Paperclip coordination.
