Then we systematically categorize existing PTMs based on a taxonomy from four different perspectives. Course 2: Natural Language Processing with Probabilistic Models. Traditionally, language has been modeled with manually-constructed grammars that describe which strings are grammatical and which are not; however, with the recent availability of massive amounts of on-line text, statistically-trained models are an attractive alternative. When modeling NLP, the odds in the fight against dimensionality can be improved by taking advantage of word order, and by recognizing that temporally closer words in the word sequence are statistically more dependent. In February 2019, OpenAI started quite a storm through its release of a new transformer-based language model called GPT-2. This post is divided into 3 parts; they are: 1. This method sets the stage for a new kind of learning, deep learning. Natural Language Processing (NLP) uses algorithms to understand and manipulate human language. That is to say, computational and memory complexity scale up in a linear fashion, not exponentially. It provides an interesting trade-off: including the direct connections between input and output causes the the training time to be cut in half (10 epochs to converge instead of 20). It improves upon past efforts by learning a feature vector for each word to represent similarity and also learning a probability function for how words connect via a neural network. You’re cursed by the amount of possibilities in the model, the amount of dimensions.
