machine reading comprehension tutorial

Shared components are filled with the same color, i.e. Instead, we’re going to use In order for our deployment to work, we need to give Cortex a configuration file, which will act as a blueprint for describing how our deployment should work.

(a) Unlike the traditional MRC problem focusing only on QA, the problem considered here is bipartite: QA and QG. This parameter sharing scheme serves as a regularization to influence the training on both tasks. Note that, the context encoder is also shared by QA and QG. Note: This tutorial is focused on building the backend of our application. One can define two problems from different directions:Careful readers may notice that there is some sort of In the real world, we know that a good reading comprehension ability means not only giving perfect answer but also asking good question. The result is “Tokyo.”In order for ELMo-BiDAF to work the way we want, it needs to be able to parse the semantic meaning of our question, and then find a suitable answer from the passage we give it. In the third sample, the generated question from our model is more readable comparing to the groundtruth.

The final output of an encoder is a concatenation of the outputs of all blocks, as illustrated in the next figure.In the attention layer, we develop a two-step attention that folds in all information observed so far for generating final sequences. The vector representation includes the word-level and the character-level information. BiDAF, S-Net, R-Net, match-LSTM, ReasonNet, Document Reader, Reinforced Mnemonic Reader, FusionNet and QANet.

blue for the answer encoder, green for the question encoder and yellow for the pointer generator. Note that, all models mentioned in this series can not even answer simple yes/no questions, e.g. Specifically, the model should be able to infer answers or questions when given the counterpart based on context.The high level architecture of our proposed Dual Ask-Answer Network is illustrated in the next figure. The idea of dual learning on deep neural network is The figure visualized three different learning paradigms that exploit the task correlations of QA and QG. For the word embedding, we use pre-trained 256-dimensional But how can one combine the word embedding with the character embedding? You can now connect it to whatever application you’re building.I’m not going to go too in depth here, but you can connect your API to your frontend using whatever technology you’re comfortable building in—assuming it can query HTTP endpoints.I decided to incorporate my bot as a Slack bot, which required a little extra finagling around Slack’s API. The ML library we’ll be using —AllenNLP—is used by Facebook, Airbnb, Amazon, and many others. Machine Reading Comprehension (MRC), or the ability to read and understand unstructured text and then answer questions about it remains a challenging task for computers. This tutorial is designed to illustrate that point by walking you through a simple, straightforward process for deploying a reading comprehension model.

I also pointed out an assumption made in this architecture: the answer is always a continuous span of a given passage. For my bot, which is a bit toy-ish and just for illustrative purposes, I’m going to build a sort of virtual teaching assistant, capable of answering my questions about physics lectures (I’ll be using Richard Feynman’s You don’t need to download AllenNLP to your local machine, as our deployment will be running on AWS, but if you’d like to play around with AllenNLP, you can install it by running We’re going to keep things simple here. This neural sequence transduction model receives string sequences as input and processes them through an embedding layer, an encoding layer, an attention layer, and finally to an output layer to generate sequences.The rectangle super-block on the side can be viewed as a decoder for QG and QA, respectively.

This tutorial is designed to illustrate that point by walking you through a simple, straightforward process for deploying a reading comprehension model.The ML library we’ll be using —AllenNLP—is used by Facebook, Airbnb, Amazon, and Before you begin, you should decide what you’ll be building, and what text it will need access to.
