CS 224D: Deep Learning for NLP

چکیده
Keyphrases: Intrinsic and extrinsic evaluations. Effect of hyperparameters on analogy evaluation tasks. Correlation of human judgment with word vector distances. Dealing with ambiguity in word using contexts. Window classification. This set of notes extends our discussion of word vectors (interchangeably called word embeddings) by seeing how they can be evaluated intrinsically and extrinsically. As we proceed, we discuss the example of word analogies as an intrinsic evaluation technique and how it can be used to tune word embedding techniques. We then discuss training model weights/parameters and word vectors for extrinsic tasks. Lastly we motivate artificial neural networks as a class of models for natural language processing tasks.

CS 224D Final Project DeepRock
We create a canonical encoding for multi-instrument MIDI songs into natural language, then use deep NLP techniques such as character LSTM variants to compose rock music that surpasses the prior state of the art and is competitive with certain pieces of music composed by human rock bands. We further define a neural network architecture for learning multi-instrument music generation in concert, b...
متن کاملA Grouping Hotel Recommender System Based on Deep Learning and Sentiment Analysis
Recommender systems are important tools for users to identify their preferred items and for businesses to improve their products and services. In recent years, the use of online services for selection and reservation of hotels have witnessed a booming growth. Customer’ reviews have replaced the word of mouth marketing, but searching hotels based on user priorities is more time-consuming. This s...
متن کاملCS 224D Final Project: Neural Network Ensembles for Sentiment Classification
We investigate the effect of ensembling on two simple models: LSTM and bidirectional LSTM. These models are used for fine-grained sentiment classification on the Stanford Sentiment Treebank dataset. We observe that ensembling improves the classification accuracy by about 3% over single models. Moreover, the more complex model, bidirectional LSTM, benefits more from ensembling.
