Four troubling trends in Machine Learning scholarship:
1. failure to distinguish between explanation and speculation;

2. failure to identify the sources of empirical gains, e.g., emphasizing unnecessary modifications to neural architectures when gains actually stem from hyper-parameter tuning;

3. mathiness: the use of mathematics that obfuscates or impresses rather than clarifies, e.g., by confusing technical and non-technical concepts; and

4. misuse of language, e.g., by choosing terms of art with colloquial connotations or by overloading established technical terms.

New paper & new dataset for spoken language understanding 🗣🎙🤖
Spoken language understanding (SLU) maps speech to meaning (or "intent"). (This is usually the actual end goal of speech recognition: you want to figure out what the speaker means/wants, not just what words they said.)

Paper: https://arxiv.org/abs/1904.03670
Code: https://github.com/lorenlugosch/pretrain_speech_model
Data: https://www.fluent.ai/research/fluent-speech-commands/

✴️ @AI_Python_EN

The conventional way to do SLU is to convert the #speech into text, and then convert the text into the intent. For a great example of this type of system, see this paper by alice coucke and others: https://arxiv.org/abs/1805.10190
Another approach is end-to-end SLU, where the speech is mapped to the intent through a single neural model. End-to-end SLU: -is simpler, -maximizes the actual metric we care about (intent accuracy), -and can harness info not present in the text, like prosody (e.g. sarcasm).
End-to-end #SLU is theoretically nice, but learning to understand speech totally from scratch is really hard—you need a ton of data to get it to work. Our solution: transfer learning! First, teach the model to recognize words and phonemes; then, teach it SLU.
Some people at GoogleAI and fb research have been doing some excellent work on end-to-end SLU, but without access to their datasets, it's impossible for most people to reproduce their results or do any useful research.
So we created an SLU dataset, Fluent Speech Commands, which http://Fluent.ai is releasing for free!

It's a simple SLU task where the goal is to predict the "action", "object", and "location" for spoken commands.
We hope that you find our dataset, #PyTorch code, pre-trained models, and paper useful. Even if you don't want to do SLU, the dataset can be used as a good old #classification task, adding to the list of open-source #audio datasets. Enjoy!

#Datacleaning can be especially problematic in the case of surveys.

Fieldwork companies will typically do some cleaning but, for IP reasons, are often reluctant to share the details of what they have done and on what grounds.

Cleaning is not as simple as flagging "bad" respondents. Many respondents answer some questions quite diligently but others less so. Their answers may reflect their true feelings, though, and are not necessarily "bad."

So, when conducting modeling, statisticians need to think carefully about the questions they may use for a particular model and which respondents (if any) to exclude from the modeling.

Even when the analytics will consist of simple cross tabs, it may not be safe to assume the data are "clean enough." It might be smart to have your statistician check the data before you begin your analysis.

We can also be proactive and alert our fieldwork company in advance regarding response patterns which suggest satisficing, or even include our own traps in the #questionnaire.

At present, many statistical approaches are challenging with huge data files because they are computationally intensive.

One consequence is that simple statistical methods and machine learners are commonly used in predictive analytics. Their predictions/classifications are normally good enough - sometimes very good - for decision-making proposes.

However, they can be difficult to interpret and may shed little light on the data generating process (DGP) - the Why.

Fortunately, most statistical methods have been designed to work with samples, some tiny by the standards of data science. It's possible to develop and deploy one model for prediction/classification and another for explanation.

Their predictions/classifications will not correlate perfectly but this is not an issue unless the correlation is poor - there is uncertainty about anything that is unknown! Correlating their predictions can be viewed as a diagnostic.

This "tandem" approach will not always be feasible or necessary but IMO is underutilized.
