suggest_discrete_uniform

The `suggest_discrete_uniform` function generates a random number from a uniform distribution. This distribution is characterized by a bound and an upper bound, and all values between these bounds have an equal probability of being chosen. Here's an example usage Python:
```python
import random
def suggest_discrete_uniform(lower_bound, upper_bound):
return random.randint(lower_bound, upper_bound)
# Example usage
lower = 1
upper = 10
random_number = suggest_discrete_uniform(lower, upper)
print(random_number)
```
In this example, `suggest_discrete_uniform` will suggest a random number between 1 and 10 (inclusive). The actual value can be any integer between the lower and upper bounds.

optuna中suggest_uniform
`optuna`是一个用于超参数优化的Python库,其中`suggest_uniform`是其提供的一种超参数建议方法之一。该方法会在指定的范围内均匀地随机生成一个浮点数作为建议值。具体来说,`suggest_uniform`方法接受三个参数:名称、下限和上限。例如,以下代码将建议一个名为`learning_rate`的超参数,其值在0.01和0.1之间均匀分布:
```python
import optuna
def objective(trial):
learning_rate = trial.suggest_uniform('learning_rate', 0.01, 0.1)
# ...
```
在每次调用`objective`函数时,`trial.suggest_uniform`方法都会生成一个新的建议值。最终,`optuna`将会从所有尝试中选择一个具有最佳性能的超参数组合。
