Running a single bAbI task
Running a joint model on all bAbI tasks
These files are also a good example of usage.
- tensorflow 0.8
- scikit-learn 0.17.1
- six 1.10.0
For a task to pass it has to meet 95%+ testing accuracy. Measured on single tasks on the 1k data.
Pass: 1,4,12,15,20
Several other tasks have 80%+ testing accuracy.
Stochastic gradient descent optimizer was used with an annealed learning rate schedule as specified in Section 4.2 of End-To-End Memory Networks
The following params were used:
- epochs: 100
- hops: 3
- embedding_size: 20

Again stochastic gradient descent optimizer was used with an annealed learning rate schedule as specified in Section 4.2 of End-To-End Memory Networks
The following params were used:
- epochs: 60

Single task results are from 10 repeated trails of the single task model accross all 20 tasks with different random initializations. The performance of the model with the lowest validation accuracy for each task is shown in the table above.
Joint training results are from 10 repeated trails of the joint model accross all tasks. The performance of the single model whose validation accuracy passed the most tasks (>= 0.95) is shown in the table above (joint_scores_run2.csv). The scores from all 10 runs are located in the results/ directory.
