n unexpected outcome of our research was that models trained with SpecAugment out-performed all prior methods even without the aid of a language model.
SpecAugment: A New Data Augmentation Method for Automatic Speech Recognition – Google Research BlogLanguage models (LMs), which are trained on a bigger corpus of text-only data, have played a significant role in improving the performance of an ASR network by leveraging information learned from text.
SpecAugment: A New Data Augmentation Method for Automatic Speech Recognition – Google Research BlogWe can now focus on improving training performance, which can be done by adding more capacity to the networks by making them larger.
SpecAugment: A New Data Augmentation Method for Automatic Speech Recognition – Google Research BlogThis suggests that the network is no longer over-fitting the training data, and that improving training performance would lead to better test performance.
SpecAugment: A New Data Augmentation Method for Automatic Speech Recognition – Google Research Blogwithout augmentation, the network achieves near-perfect performance on the training set, while grossly under-performing on both the clean and noisy dev set.

Problem Set 4: Memory ScrambleAlice turns over the top left card. She controls that card for the moment (rule 1-B).
Problem Set 4: Memory Scramblehe Interpreter pattern makes it easier to add new variants, because we don’t have to change any of our existing code: we just need to implement all the various operations as methods in the new variant class.
Reading 19: Little LanguagesTo understand the contrast between the Visitor pattern and the Interpreter pattern, it helps to imagine all the code for all the operations of Formula as if it were written down in a table, with the variant classes across the top and the operations down the side. An entry in the table is the code that implements that operation for that variant. Here is part of the table (written compactly in mathematical notation rather than TypeScript):
Reading 19: Little LanguagesA visitor represents a function over a recursive type: we can create an instance of a particular FormulaFunction, pass it around, apply it as needed, etc. If the function we’re representing takes additional parameters, we can make them arguments to the visitor constructor and store those values in fields to be referenced as we go. The exercise at the end of this section explores this idea.
Reading 19: Little LanguagesA visitor implements switch over types: the code above to implement VariablesInFormula reads pretty closely to our original goal of a switch statement, but each case is given its own onVariant method. The dynamic dispatch in the visitor implicitly acts like a switch statement, executing the callFunction for the appropriate concrete variant corresponding to the dynamic type.
Reading 19: Little LanguagesWhat we have created with the FormulaFunction type and callFunction operation is a special kind of iterator, one that walks over the tree structure of a Formula and processes nodes in the tree one at a time. The name for this pattern is Visitor:
Reading 19: Little LanguagesWe use double dispatch, which means two method calls in succession:
Reading 19: Little LanguagesIf we wish to add a new operation to our type, we must modify the interface and every implementing class. If there are many concrete variants that already have substantial code, perhaps written and maintained by other programmers, this change will be more difficult to make than if we could keep the code for the new operation in its own separate location.
