snorkel | quickly generating training data with weak supervision | Machine Learning library

My problem is as follow: I have several datasets (900K, 1M7 and 1M7 entries) in csv format which I load into multiple Dask Dataframe. Then I concatenate them all in one Dask Dataframe that I can feed to my Snorkel Applier, which applies a bunch of Labeling Function to each row of my Dataframe and return a numpy array with as many rows as there are in the Dataframe and as many columns as there are Labeling Functions.

The call to Snorkel Applier seems to take forever when I do that with 3 datasets (more than 2 days...). However if I just run the code with only the first dataset, the call takes around 2 hours. Of course I don't do the concatenation step.

So I was wondering how can this be ? Should I change the number of partitions in the concatenated Dataframe ? Or maybe I'm using Dask badly in the first place ?

Here is the code I'm using:

my database contains two tables named category and sport:

I installed snorkel using conda and when I try to run - from snorkel.labeling import labeling_function it throws the following error - ModuleNotFoundError: No module named 'snorkel.labeling'.

I tried looking up for a solution on Github, but unfortunately, I couldn't follow through. I have also tried installing nb_conda_kernels, to make all your conda environments available in jupyterbut it didn't help. Also tried creating a separate env, installing snorkel and launching jupyter notebook from the snorkel's environment, and it didn't work either. Any form of help is much appreciated!

Thanks in advance!

I have a set of features to build labelling functions (set A) and another set of features to train a sklearn classifier (set B)

The generative model will output a set of probabilisitic labels which i can use to train my classifier.

Do i need to add in the features (set A) that i used for the labelling functions into my classifier features? (set B) Or just use the labels generated to train my classifier?

I was referencing the snorkel spam tutorial and i did not see them use the features in the labelling function set to train a new classifier.

As seem in cell 47, featurization is done entirely using a CountVectorizer:

I made a map last year of survey points using Rgooglemaps in R. It was a simple map displaying points at which different surveys were conducted. Since google have updated their licence I want to re-create this map using the getNOAA function using marmap.

Here is my old map

I'm having problems getting my JavaScript to function correctly with my html. I need the "activity" drop-down box to work with the "city" drop-down box. For example, if I select "Brisbane" and then click the activity box, the options should be "City Tours, Sports, Cycling, Museums, Boating" and it will be different depending on which city that is selected.

I am currently working on the project listed below. So far I am having trouble accessing my class from my program. I'm not sure if it's something that I am missing or if I'm just in over my head. I will include the code I have came up with so far.

You will be graded on:

• Your code must compile. If your code has a compile error and does not run, you will not receive a passing score.
• Your code must follow the guidelines provided. For example: Your final code must contain 3 classes. If all your code is done from within the main() with a series of WriteLine() methods, you will not do well.

Waikiki Hilton Beach Rentals Application:

You will be creating a program for Waikiki Hilton Beach Rentals. Here guests of the Hilton can rent beach equipment such as flotation rafts, snorkel gear, chairs, umbrellas and paddle boats.

Your application will get the guest name, items rented, qty of each item rented and total minutes rented. A guest can rent as many items as they would like, and multiple quantities. You can assume that all items are rented for the same time frame. So a guest can rent 2 chairs, and snorkel gear – but all for 65 minutes. (not chairs for 15, and the snorkel gear for 45 for example)

You will be creating three classes, the BeachRentalsApp which will be the entry point of the program, a Rental class which you will be using to create rental objects, and a guestclass which holds the guest information.

BeachRentalsApp – where the program begins. This should create a guest object. Your guest object holds the guest name, contract number and an array of Rental objects. The app should display a welcome message, and then get the guest info as well as the rental info. All of the info displayed and gathered in the main() method should be called from methods within the BeachRentalsApp class.

Contains the following methods:

• main() – instantiates a Guest object, and as many Rental objects as required. Rental objects are then stored in an array data element in the Guest object ie itemsRented[ ]. The main method should call methods to get input and display data. Methods to call in this class should include:
• Display a welcome message
• Get the guest name
• Get the contract number
• Gets minutes rented – a guest has to rent for a minimum of an hour and no more than 8 hours.
• Gets the item to rent and qty
• displays the static array from the Rental Class
• gets the qty and item to rent
• Displays the final rental info:
• Guest name
• For each item: item rented, total cost of rental (price of item * rental period)
• A final total of all items rented

Guest – A class that holds guest info

Properties:

• Guest Name
• Contract Number (ie K168)
• # Hours rented
• # Minutes rented
• Items Rented (an array of rental objects)

Constructors as appropriate: requires a minimum of guest name to instantiate a guest object.

Methods:

• Sets the contract Number. If no number is provided, create a random contract number. It should start with the first letter of the customer name, and then a randomly generated additional 4 numbers.
• Accepts the minutes rented and sets the class data fields (# hours rented, # minutes rented) accordingly.

Rental – A class that describes a rental

Constructors as appropriate. Users of this class need a minimum of a rental item to instantiate an object.

Static members:

• an array of the rental items available (such as flotation rafts, snorkel gear, chairs, umbrellas, paddle boats)
• The hourly rate for each of the following is:
• flotation raft – $15
• snorkel gear – $25
• chairs – $8
• umbrella – $10
• paddle boat - $40

Properties:

• item Rented (ie umbrella)
• qty rented (ie 3 umbrellas)
• total rental price (ie umbrella cost $10 * rental period * 3 umbrellas)

Methods

• static method that displays the items available for rental
• calculates total price - calculated in half hour increments. For example. An umbrella costs $8 per hour. If the rental period is 30 minutes, the price is $4. Otherwise the price is $8. So a rental of 75 minutes costs $12. (1 hour is $8 and additional up to 30 minutes is $4) A rental of 45 minutes costs $8.

Code:

I have a UITableView that contains a list of categories (in this example, list of sports types i.e. Water and Land based)

Each cell in this table then has a list of sports associated with the type of sport displayed in a nested UICollectionView. For example, water based will have Surfing and swimming.

Think Netflix - with Vertical scrolling categories with horizontally scrollable subcategories.

Here is example JSON (Note that the JSON shown is just to describe the structure. I have in fact stored this in RealmDb)

im making a "fake" Vacation planning guide it asks the user to select a place then a activity they wish to do i cant seem to make it add a decimal total like 199.99 in this case to a global total what am i doing wrong here?

//this is all in the public main class by the way
