Data augmentation in nlp: best practices from a kaggle master neptune.ai they are popular in computer vision applications, but they can be just as powerful for nlp. @ratthachat: there are a couple of interesting cluster areas but for the most parts, the class labels overlap rather significantly (at least for the naive rebalanced set i'm using) i take it to mean that operating on the raw text (with or w o standard preprocessing) is still not able to provide enough variation for t sne to visually distinguish between the classes in semantic space.

However, kaggle, one of the world’s finest platforms for data scientists, gives aspirants the best possible introduction into the tricky world of data. analytics india magazine has been exclusively covering the stories of top kagglers, and today we compile a few nuggets of wisdom from those interviews that can guide an aspirant. Unlike computer vision where using image data augmentation is standard practice, augmentation of text data in nlp is pretty rare. this is because trivial operations for images like rotating an image a few degrees or converting it into grayscale doesnt change its semantics. The kaggle competition for house prices gives a data set that is already split into a training and testing data set so that saves us a step. it’s important to shuffle and split your data into a training and testing set because the testing set is used to measure the performance of our model. how well our model generalizes to new data. Ahmet currently works as a senior data scientist at nvidia and brings many years of experience across diverse firms to give you an insight into the power of data science and nlp. also, he has a masters’s degree in artificial intelligence from ku leuven university. this is the second interview in the series of kaggle grandmaster interviews. “weakly supervised learning: introduction and best practices”, by kristina khvatova, software engineer at softec s.p.a. kristina e x plained what weakly supervised learning means and what kind of strategies are used to get more labeled training data. weakly supervised learning is an umbrella covering several processes which attempt to build predictive models by learning with weak supervision.

Kaggle competition is always a great place to practice and learn something new. however, the best solution on kaggle does not guarantee the best solution of a business problem. the example of quora question pairs kaggle competition illustrates how important it is to be very careful and considerate while preparing a training data. Recently, i started up with an nlp competition on kaggle called quora question insincerity challenge. it is an nlp challenge on text classification and as the problem has become more clear after working through the competition as well as by going through the invaluable kernels put up by the kaggle experts, i thought of sharing the knowledge. Distracted drivers and data augmentation. building on challenges with processing image data, another kaggle competition david participated in was the state farm distracted driver detection challenge. the problem was to identify distracted drivers by reviewing images to determine whether the driver was doing things like playing with the radio. The second place team used fmix, a variant of mixed sample data augmentation, which is a class of augmentations that also include cutmix and mixup. kaggle competitions. grow your data science skills by competing in kaggle nlp, voice, tabular, etc. he is passionate about learning and exploring new applications of ml, especially those. Today, i’m very excited to be talking from someone from the kaggle team: i’m talking to dr. rachael tatman: data scientist at kaggle. rachael holds a ph.d. in linguistics from the university of washington, as well as a masters in linguistics from the university of washington as well.
