deep_consensus.py | '''
Distributed Tensorflow 1.12.0 example of using data parallelism and the consensus worker communication scheme.
Trains a deep convolutional neural network on MNIST for 10 epochs on n_nodes machines using one parameter server.
The goal is to put minimum workload on the parameter server such that all computations are assigned to the workers.
The distribution model is the consensus model, based on which each worker communicates only with its neighbours based
on the topology provided as input (supported: 'full', 'ring', 'random'), averages their computed gradients and applies the
aggregation to its current parameter vector(s); then it proceeds to compute the next gradient and send it to its neighbors.

deep_consensus.py | '''
Distributed Tensorflow 1.12.0 example of using data parallelism and the consensus worker communication scheme.
Trains a deep convolutional neural network on MNIST for 10 epochs on n_nodes machines using one parameter server.
The goal is to put minimum workload on the parameter server such that all computations are assigned to the workers.
The distribution model is the consensus model, based on which each worker communicates only with its neighbours based
on the topology provided as input (supported: 'full', 'ring', 'random'), averages their computed gradients and applies the
aggregation to its current parameter vector(s); then it proceeds to compute the next gradient and send it to its neighbors.

deep_consensus.py | '''
Distributed Tensorflow 1.12.0 example of using data parallelism and the consensus worker communication scheme.
Trains a deep convolutional neural network on MNIST for 10 epochs on n_nodes machines using one parameter server.
The goal is to put minimum workload on the parameter server such that all computations are assigned to the workers.
The distribution model is the consensus model, based on which each worker communicates only with its neighbours based
on the topology provided as input (supported: 'full', 'ring', 'random'), averages their computed gradients and applies the
aggregation to its current parameter vector(s); then it proceeds to compute the next gradient and send it to its neighbors.

# # Assignment 2 - Introduction to NLTK
#
# In part 1 of this assignment you will use nltk to explore the Herman Melville novel Moby Dick. Then in part 2 you will create a spelling recommender function that uses nltk to find words similar to the misspelling.
# ## Part 1 - Analyzing Moby Dick
# In[82]:
import nltk
import pandas as pd
import numpy as np
# If you would like to work with the raw text you can use 'moby_raw'
with open('moby.txt', 'r') as f:
moby_raw = f.read()
# If you would like to work with the novel in nltk.Text format you can use 'text1'
moby_tokens = nltk.word_tokenize(moby_raw)
text1 = nltk.Text(moby_tokens)
# ### Example 1
#
# How many tokens (words and punctuation symbols) are in text1?
#
# *This function should return an integer.*
# In[83]:
def example_one():
return len(nltk.word_tokenize(moby_raw)) # or alternatively len(text1)
example_one()
# ### Example 2
#
# How many unique tokens (unique words and punctuation) does text1 have?
#
# *This function should return an integer.*
# In[84]:
def example_two():
return len(set(nltk.word_tokenize(moby_raw))) # or alternatively len(set(text1))
example_two()
# ### Example 3
#
# After lemmatizing the verbs, how many unique tokens does text1 have?
#
# *This function should return an integer.*
# In[85]:
from nltk.stem import WordNetLemmatizer
def example_three():
lemmatizer = WordNetLemmatizer()
lemmatized = [lemmatizer.lemmatize(w,'v') for w in text1]
return len(set(lemmatized))
example_three()
# ### Question 1
#
# What is the lexical diversity of the given text input? (i.e. ratio of unique tokens to the total number of tokens)
#
# *This function should return a float.*
# In[86]:
tokens = nltk.word_tokenize(moby_raw)
unique_tokens = set(tokens)
lemmatizer = WordNetLemmatizer()
stems = [lemmatizer.lemmatize(w,'v') for w in text1]

tags = nltk.pos_tag(tokens)
moby_sents = nltk.sent_tokenize(moby_raw)
def answer_one():
return len(unique_tokens) / len(tokens)

# ### Question 2
#
# What percentage of tokens is 'whale'or 'Whale'?
#
# *This function should return a float.*
# In[100]:
def answer_two():
return len([tok for tok in tokens if tok == 'whale' or tok == 'Whale']) / len(tokens) * 100
answer_two()
# ### Question 3
#
# What are the 20 most frequently occurring (unique) tokens in the text? What is their frequency?
#
# *This function should return a list of 20 tuples where each tuple is of the form `(token, frequency)`. The list should be sorted in descending order of frequency.*
# In[88]:
token_freq = nltk.FreqDist(tokens)
token_freq_sorted = sorted(token_freq.items(), key=lambda x: x[1], reverse=True)
def answer_three():
return token_freq_sorted[:20]
answer_three()
# ### Question 4
#
# What tokens have a length of greater than 5 and frequency of more than 150?
#
# *This function should return an alphabetically sorted list of the tokens that match the above constraints. To sort your list, use `sorted()`*
# In[89]:
def answer_four():
return sorted([tok for tok in unique_tokens if len(tok) > 5 and token_freq[tok] > 150])
answer_four()
# ### Question 5
#
# Find the longest word in text1 and that word's length.
#
# *This function should return a tuple `(longest_word, length)`.*
# In[90]:
def answer_five():
return max([(tok, len(tok)) for tok in unique_tokens], key=lambda k: k[1])
answer_five()
# ### Question 6
#
# What unique words have a frequency of more than 2000? What is their frequency?
#
# "Hint: you may want to use `isalpha()` to check if the token is a word and not punctuation."
#
# *This function should return a list of tuples of the form `(frequency, word)` sorted in descending order of frequency.*
# In[91]:
def answer_six():
return [(freq, tok) for tok, freq in token_freq_sorted if freq > 2000 and tok.isalpha()]
answer_six()
# ### Question 7
#
# What is the average number of tokens per sentence?
#
# *This function should return a float.*
# In[92]:
def answer_seven():
tokens = 0
sents = 0
for sent in moby_sents:
tokens += len(nltk.word_tokenize(sent))
sents += 1
return tokens / sents
answer_seven()
# ### Question 8
#
# What are the 5 most frequent parts of speech in this text? What is their frequency?
#
# *This function should return a list of tuples of the form `(part_of_speech, frequency)` sorted in descending order of frequency.*
# In[93]:
def answer_eight():
import collections
d = collections.defaultdict(int)
for tok, pos in tags:
d[pos] += 1
return sorted(d.items(), key=lambda x: x[1], reverse=True)[:5]
answer_eight()
# ## Part 2 - Spelling Recommender
#
# For this part of the assignment you will create three different spelling recommenders, that each take a list of misspelled words and recommends a correctly spelled word for every word in the list.
#
# For every misspelled word, the recommender should find find the word in `correct_spellings` that has the shortest distance*, and starts with the same letter as the misspelled word, and return that word as a recommendation.
#
# *Each of the three different recommenders will use a different distance measure (outlined below).
#
# Each of the recommenders should provide recommendations for the three default words provided: `['cormulent', 'incendenece', 'validrate']`.
