# Active Learning System Expert
Эксперт по системам активного обучения для машинного обучения.
## Основные стратегии
- **Uncertainty Sampling**: Выбор примеров с наименьшей уверенностью модели
- **Query by Committee**: Использование разногласий ансамбля
- **Expected Model Change**: Выбор наиболее информативных образцов
- **Diversity-based Selection**: Покрытие пространства признаков
## Основной цикл активного обучения
```python
from modAL import ActiveLearner
from modAL.uncertainty import uncertainty_sampling
class ActiveLearningSystem:
def __init__(self, initial_labeled_pool, unlabeled_pool):
self.labeled_X, self.labeled_y = initial_labeled_pool
self.unlabeled_X = unlabeled_pool
self.learner = ActiveLearner(
estimator=RandomForestClassifier(n_estimators=100),
query_strategy=uncertainty_sampling,
X_training=self.labeled_X,
y_training=self.labeled_y
)
def query_and_update(self, batch_size=10, oracle_func=None):
query_indices = []
temp_unlabeled = self.unlabeled_X.copy()
for _ in range(min(batch_size, len(temp_unlabeled))):
query_idx, query_instance = self.learner.query(temp_unlabeled)
query_indices.append(query_idx)
temp_unlabeled = np.delete(temp_unlabeled, query_idx, axis=0)
queried_X = self.unlabeled_X[query_indices]
queried_y = oracle_func(queried_X) if oracle_func else self.simulate_oracle(queried_X)
self.learner.teach(queried_X, queried_y)
self.unlabeled_X = np.delete(self.unlabeled_X, query_indices, axis=0)
return query_indices, queried_X, queried_y
```
## Query by Committee
```python
class CommitteeActiveLearner:
def __init__(self, X_initial, y_initial):
self.committee = [
RandomForestClassifier(n_estimators=50),
GradientBoostingClassifier(n_estimators=50),
SVC(probability=True)
]
for clf in self.committee:
clf.fit(X_initial, y_initial)
def query_by_committee(self, X_pool, n_instances=1):
disagreements = []
for x in X_pool:
predictions = [clf.predict_proba([x])[0] for clf in self.committee]
avg_pred = np.mean(predictions, axis=0)
disagreement = -np.sum(avg_pred * np.log(avg_pred + 1e-10))
disagreements.append(disagreement)
selected_indices = np.argsort(disagreements)[-n_instances:]
return selected_indices, X_pool[selected_indices]
```
## Мониторинг производительности
```python
class ActiveLearningMonitor:
def track_performance(self, model, X_test, y_test, n_annotations):
accuracy = accuracy_score(y_test, model.predict(X_test))
self.performance_history.append(accuracy)
self.annotation_costs.append(n_annotations)
def calculate_learning_efficiency(self):
performance_gains = np.diff(self.performance_history)
annotation_increments = np.diff(self.annotation_costs)
efficiency = performance_gains / annotation_increments
return {
'current_efficiency': efficiency[-1],
'average_efficiency': np.mean(efficiency),
'efficiency_trend': np.polyfit(range(len(efficiency)), efficiency, 1)[0]
}
def suggest_stopping_criterion(self):
efficiency = self.calculate_learning_efficiency()
if efficiency['current_efficiency'] < 0.001:
return "Consider stopping - low marginal gains"
return "Continue learning"
```
## Лучшие практики
### Стратегия холодного старта
- Используйте стратифицированную выборку для начального набора
- Обеспечьте представленность всех классов
- Начинайте минимум с 5-10 примеров на класс
### Оптимизация размера батча
- Маленькие батчи (5-20) для высокой неопределенности
- Большие батчи (50-100) для дорогой аннотации
- Учитывайте усталость аннотатора
### Распространенные ловушки
- Игнорирование дисбаланса классов
- Чрезмерная зависимость от уверенности без калибровки
- Пренебрежение согласованностью аннотаторов
- Неучет шума аннотацииRelated Skills

agent-memory-systems
Memory is the cornerstone of intelligent agents. Without it, every interaction starts from zero. This skill covers the architecture of agent memory: short-term (context window), long-term (vector stores), and the cognitive architectures that organize them. Key insight: Memory isn't just storage - it's retrieval. A million stored facts mean nothing if you can't find the right one. Chunking, embedding, and retrieval strategies determine whether your agent remembers or forgets. The field is fragm

Expert embedded systems engineer specializing in microcontroller programming, RTOS development, and hardware optimization. Masters low-level programming, real-time constraints, and resource-limited environments with focus on reliability, efficiency, and hardware-software integration.
agent-context-system
A persistent local-only memory system for AI coding agents. Two files, one idea — AGENTS.md (committed, shared) + .agents.local.md (gitignored, personal). Agents read both at session start, update the scratchpad at session end, and promote stable patterns over time. Works across Claude Code, Cursor, Copilot, Windsurf. Subagent-ready. No plugins, no infrastructure, no background processes.
