Let's get started!
Project Requirement :
We want to design a neural network that segments an English word into prefixes, root, and suffixes using a BIO labelling scheme.
For example, the word “unprepossessing” has the labelling: (“u”, B-pre), (“n”, I-pre), (“p”, B-pre), (“r”, I-pre), (“e”, I-pre), (“p”, B-root), (“o”, I-root), (“s”, I-root), (“s”, I-root), (“e”, I-root), (“s”, I-root), (“s”, I-root), (“i”, B-suf), (“n”, I-suf), (“g”, I-suf).
Fully specify a neural network to solve this problem. Describe:
how the inputs and outputs are encoded
the structure of the network
the cost function used
Describe the network in enough detail that one could implement it using PyTorch.
You do not need to define batch sizes, learning rates, and other optimization parameters.
Please work independently. You should turn in a document (.txt, .md, or .pdf) answering the above.
Solution Approach
In this project, we aimed to design a neural network capable of segmenting English words into prefixes, roots, and suffixes using a BIO labeling scheme. To achieve this, we employed various techniques and methods:
Bi-LSTM Architecture: We utilized a Bidirectional Long Short-Term Memory (Bi-LSTM) neural network architecture. This architecture is well-suited for sequence labeling tasks like ours, as it can capture contextual information from both past and future tokens in the input sequence.
Encoding Inputs: The inputs, comprising English words, were encoded as sequences of indices representing each word in a fixed vocabulary. These indices were then fed into an embedding layer to obtain dense vector representations for each word.
BIO Labeling Scheme: We adopted the BIO labeling scheme to label each token in the input sequence as either beginning (B), inside (I), or outside (O) a prefix, root, or suffix, respectively.
Forward Algorithm: To compute the partition function efficiently, we implemented the forward algorithm using dynamic programming. This algorithm enabled us to compute the probability of observing a sequence given the model parameters.
Viterbi Decoding: For predicting the most likely sequence of labels, we employed the Viterbi decoding algorithm. This algorithm efficiently finds the optimal sequence of labels by considering the transition probabilities between labels and the emission probabilities of observed features.
Loss Function: To train the neural network, we defined a negative log-likelihood loss function. This loss function penalizes deviations between predicted and true label sequences, encouraging the model to learn meaningful representations for segmenting words.
Training Process: During the training process, we iteratively optimized the model parameters using stochastic gradient descent (SGD) with weight decay. This optimization process aimed to minimize the defined loss function across the training dataset.
