                              Implementation Steps                              

 1 Implement Q-learning agent: Create a Q-learning agent that will adjust the   
   learning rate based on the current state (validation loss, current learning  
   rate).                                                                       
 2 Integrate Q-learning agent into training loop: Modify the training loop to   
   incorporate the Q-learning agent's adjustments to the learning rate at each  
   evaluation interval.                                                         
 3 Run experiments: Execute the planned experiments and compare the results with
   the baseline.

After implementing the Q-learning agent and integrating it into the training    
loop, we will run the experiments using the command python experiment.py        
--out_dir=run_i where i is the run number.                                      

Please proceed to run the first experiment using the command:

Once the first experiment is complete, we can proceed with the subsequent       
experiments.

To fix the error, we need to convert the val_loss tensor to a Python float      
before rounding it. We can do this by calling the .item() method on the tensor.

 Description: This run implemented Q-learning for dynamic learning rate         
 adaptation. The Q-learning agent adjusted the learning rate based on the curre 
 state (validation loss, current learning rate) and used a reward signal derive 
 from validation performance to update the Q-values. The training loop was      
 modified to incorporate the RL agent's adjustments to the learning rate at eac 
 evaluation interval. The results were compared with the baseline model using   
 static or heuristic-based learning rate schedules on multiple datasets         
 (shakespeare_char, enwik8, text8).

Next, let's implement the next experiment. For this experiment, we will use a   
different initial learning rate to see how it affects the Q-learning adaptation.
We will set the initial learning rate to 2e-3 for shakespeare_char and 1e-3 for 
enwik8 and text8.

 from validation performance to update the Q-values. The training loop was      
 modified to incorporate the RL agent's adjustments to the learning rate at eac

Description: This run implemented Q-learning for dynamic learning rate 
adaptation with a different reward signal. Instead of using the negative 
validation loss as the reward, the improvement in validation loss was used. The 
Q-learning agent adjusted the learning rate based on the current state 
(validation loss, current learning rate) and used the reward signal derived from
the improvement in validation performance to update the Q-values. The training 
loop was modified to incorporate the RL agent's adjustments to the learning rate
at each evaluation interval. The results were compared with the baseline model 
using static or heuristic-based learning rate schedules on multiple datasets 
(shakespeare_char, enwik8, text8).

Here are the changes needed:

```python

        self.epsilon = epsilon

        self.epsilon = epsilon
        self.initial_epsilon = epsilon

implemented Q-learning for dynamic learning rate adaptation with a different    
reward signal. Instead of using the negative validation loss as the reward, the 
improvement in validation loss was used. The Q-learning agent adjusted the      
learning rate based on the current state (validation loss, current learning     
rate) and used the reward signal derived from the improvement in validation     
performance to update the Q-values. The training loop was modified to           
incorporate the RL agent's adjustments to the learning rate at each evaluation  
interval. The results were compared with the baseline model using static or     
heuristic-based learning rate schedules on multiple datasets (shakespeare_char,

## Run 3: Q-learning with reward signal based on improvement in validation loss
Results: {'shakespeare_char': {'final_train_loss_mean': 0.8062439958254496, 'best_val_loss_mean': 1.461962143580119, 'total_train_time_mean': 75.80110216140747, 'avg_inference_tokens_per_second_mean': 668.3102066342188}, 'enwik8': {'final_train_loss_mean': 0.9246289730072021, 'best_val_loss_mean': 0.9944368004798889, 'total_train_time_mean': 796.9592888355255, 'avg_inference_tokens_per_second_mean': 688.6266631351763}, 'text8': {'final_train_loss_mean': 0.9843199849128723, 'best_val_loss_mean': 0.961367666721344, 'total_train_time_mean': 791.6123127937317, 'avg_inference_tokens_per_second_mean': 658.961942825521}}
Description: This run implemented Q-learning for dynamic learning rate adaptation with a different reward signal. Instead of using the negative validation loss as the reward, the improvement in validation loss was used. The Q-learning agent adjusted the learning rate based on the current state (validation loss, current learning rate) and used the reward signal derived from the improvement in validation performance to update the Q-values. The training loop was modified to incorporate the RL agent's adjustments to the learning rate at each evaluation interval. The results were compared with the baseline model using static or heuristic-based learning rate schedules on multiple datasets (shakespeare_char, enwik8, text8).

Description: This run implemented Q-learning for dynamic learning rate adaptation with an epsilon decay strategy. Instead of using a fixed epsilon value for exploration, an epsilon decay strategy was used where epsilon decreases over time. The Q-learning agent adjusted the learning rate based on the current state (validation loss, current learning rate) and used a reward signal derived from validation performance to update the Q-values. The training loop was modified to incorporate the RL agent's adjustments to the learning rate at each evaluation interval. The results were compared with the baseline model using static or heuristic-based learning rate schedules on multiple datasets (shakespeare_char, enwik8, text8).

Next, let's propose the next experiment. We will use a different discount factor (gamma) for the Q-learning agent to see how it affects the learning rate adaptation.

Now, you can run the next experiment with the command:
```sh

```
To modify plot.py to generate the most relevant plots for the final writeup and 
fill in the "labels" dictionary with the correct names for each run, we will:   

 1 Update the labels dictionary to include all relevant runs.                   
 2 Ensure that the plots are generated for each dataset and saved with          
   appropriate filenames.

These changes will ensure that the plots are generated for each dataset and     
saved with appropriate filenames, and the labels dictionary will include all    
relevant runs.
