    "This tutorial contains an introduction to word embeddings. You will train your own word embeddings using a simple Keras model for a sentiment classification task, and then visualize them in the [Embedding Projector](http://projector.tensorflow.org) (shown in the image below). \n",

    "## Representing text as numbers\n",
    "\n",
    "Machine learning models take vectors (arrays of numbers) as input. When working with text, the first thing you must do is come up with a strategy to convert strings to numbers (or to \"vectorize\" the text) before feeding it to the model. In this section, you will look at three strategies for doing so.\n",
    "\n",
    "### One-hot encodings\n",
    "\n",
    "As a first idea, you might \"one-hot\" encode each word in your vocabulary. Consider the sentence \"The cat sat on the mat\". The vocabulary (or unique words) in this sentence is (cat, mat, on, sat, the). To represent each word, you will create a zero vector with length equal to the vocabulary, then place a one in the index that corresponds to the word. This approach is shown in the following diagram.\n",
    "\n",
    "<img src=\"images/one-hot.png\" alt=\"Diagram of one-hot encodings\" width=\"400\" />\n",
    "\n",
    "To create a vector that contains the encoding of the sentence, you could then concatenate the one-hot vectors for each word.\n",
    "\n",
    "Key point: This approach is inefficient. A one-hot encoded vector is sparse (meaning, most indices are zero). Imagine you have 10,000 words in the vocabulary. To one-hot encode each word, you would create a vector where 99.99% of the elements are zero.\n",
    "\n",
    "### Encode each word with a unique number\n",
    "\n",
    "A second approach you might try is to encode each word using a unique number. Continuing the example above, you could assign 1 to \"cat\", 2 to \"mat\", and so on. You could then encode the sentence \"The cat sat on the mat\" as a dense vector like [5, 1, 4, 3, 5, 2]. This approach is efficient. Instead of a sparse vector, you now have a dense one (where all elements are full).\n",
    "\n",
    "There are two downsides to this approach, however:\n",
    "\n",
    "* The integer-encoding is arbitrary (it does not capture any relationship between words).\n",
    "\n",
    "* An integer-encoding can be challenging for a model to interpret. A linear classifier, for example, learns a single weight for each feature. Because there is no relationship between the similarity of any two words and the similarity of their encodings, this feature-weight combination is not meaningful.\n",
    "\n",
    "### Word embeddings\n",
    "\n",
    "Word embeddings give us a way to use an efficient, dense representation in which similar words have a similar encoding. Importantly, you do not have to specify this encoding by hand. An embedding is a dense vector of floating point values (the length of the vector is a parameter you specify). Instead of specifying the values for the embedding manually, they are trainable parameters (weights learned by the model during training, in the same way a model learns weights for a dense layer). It is common to see word embeddings that are 8-dimensional (for small datasets), up to 1024-dimensions when working with large datasets. A higher dimensional embedding can capture fine-grained relationships between words, but takes more data to learn.\n",
    "\n",
    "<img src=\"images/embedding2.png\" alt=\"Diagram of an embedding\" width=\"400\"/>\n",
    "\n",
    "Above is a diagram for a word embedding. Each word is represented as a 4-dimensional vector of floating point values. Another way to think of an embedding is as \"lookup table\". After these weights have been learned, you can encode each word by looking up the dense vector it corresponds to in the table."

But I thought it might get better. It Didn't. Anyone who actually enjoyed this movie is one seriously sick and twisted individual. No wonder us Australians/New Zealanders have a terrible reputation when it comes to making movies. Everything about this movie is horrible, from the acting to the editing. I don't even normally write reviews on here, but in this case I'll make an exception. I only wish someone had of warned me before I hired this catastrophe\"\n",
      "1 b'This movie is SOOOO funny!!! The acting is WONDERFUL, the Ramones are sexy, the jokes are subtle, and the plot is just what every high schooler dreams of doing to his/her school. I absolutely loved the soundtrack as well as the carefully placed cynicism. If you like monty python, You will love this film. This movie is a tad bit \"grease\"esk (without all the annoying songs). The songs that are sung are likable; you might even find yourself singing these songs once the movie is through. This musical ranks number two in musicals to me (second next to the blues brothers). But please, do not think of it as a musical per say; seeing as how the songs are so likable, it is hard to tell a carefully choreographed scene is taking place. I think of this movie as more of a comedy with undertones of romance. You will be reminded of what it was like to be a rebellious teenager; needless to say, you will be reminiscing of your old high school days after seeing this film. Highly recommended for both the family (since it is a very youthful but also for adults since there are many jokes that are funnier with age and experience.'\n",
      "0 b\"Alex D. Linz replaces Macaulay Culkin as the central figure in the third movie in the Home Alone empire. Four industrial spies acquire a missile guidance system computer chip and smuggle it through an airport inside a remote controlled toy car. Because of baggage confusion, grouchy Mrs. Hess (Marian Seldes) gets the car. She gives it to her neighbor, Alex (Linz), just before the spies turn up. The spies rent a house in order to burglarize each house in the neighborhood until they locate the car. Home alone with the chicken pox, Alex calls 911 each time he spots a theft in progress, but the spies always manage to elude the police while Alex is accused of making prank calls. The spies finally turn their attentions toward Alex, unaware that he has rigged devices to cleverly booby-trap his entire house. Home Alone 3 wasn't horrible, but probably shouldn't have been made, you can't just replace Macauley Culkin, Joe Pesci, or Daniel Stern. Home Alone 3 had some funny parts, but I don't like when characters are changed in a movie series, view at own risk.\"\n",
      "0 b\"There's a good movie lurking here, but this isn't it. The basic idea is good: to explore the moral issues that would face a group of young survivors of the apocalypse. But the logic is so muddled that it's impossible to get involved.<br /><br />For example, our four heroes are (understandably) paranoid about catching the mysterious airborne contagion that's wiped out virtually all of mankind. Yet they wear surgical masks some times, not others. Some times they're fanatical about wiping down with bleach any area touched by an infected person. Other times, they seem completely unconcerned.<br /><br />Worse, after apparently surviving some weeks or months in this new kill-or-be-killed world, these people constantly behave like total newbs. They don't bother accumulating proper equipment, or food. They're forever running out of fuel in the middle of nowhere. They don't take elementary precautions when meeting strangers. And after wading through the rotting corpses of the entire human race, they're as squeamish as sheltered debutantes. You have to constantly wonder how they could have survived this long... and even if they did, why anyone would want to make a movie about them.<br /><br />So when these dweebs stop to agonize over the moral dimensions of their actions, it's impossible to take their soul-searching seriously. Their actions would first have to make some kind of minimal sense.<br /><br />On top of all this, we must contend with the dubious acting abilities of Chris Pine. His portrayal of an arrogant young James T Kirk might have seemed shrewd, when viewed in isolation. But in Carriers he plays on exactly that same note: arrogant and boneheaded. It's impossible not to suspect that this constitutes his entire dramatic range.<br /><br />On the positive side, the film *looks* excellent. It's got an over-sharp, saturated look that really suits the southwestern US locale. But that can't save the truly feeble writing nor the paper-thin (and annoying) characters. Even if you're a fan of the end-of-the-world genre, you should save yourself the agony of watching Carriers.\"\n",
      "0 b'I saw this movie at an actual movie theater (probably the $2.00 one) with my cousin and uncle. We were around 11 and 12, I guess, and really into scary movies. I remember being so excited to see it because my cool uncle let us pick the movie (and we probably never got to do that again!) and sooo disappointed afterwards!! Just boring and not scary. The only redeeming thing I can remember was Corky Pigeon from Silver Spoons, and that wasn\\'t all that great, just someone I recognized. I\\'ve seen bad movies before and this one has always stuck out in my mind as the worst. This was from what I can recall, one of the most boring, non-scary, waste of our collective $6, and a waste of film. I have read some of the reviews that say it is worth a watch and I say, \"Too each his own\", but I wouldn\\'t even bother. Not even so bad it\\'s good.'\n"
