## Non-verbal questions

I have a requirement for at-least 2000 non-verbal reasoning questions and possibly more at a later point (Each project will be to deliver a 100 questions and depending on the quality of questions I get I would like to employ the freelancer for a longer period). For this I will need to understand the profile of the bidder to ensure that I will get the quality.

1. Questions will have to be original designs and not copied from any other sources

2. Questions will have to be based on the different types (samples will be provided)

3. The project is for 100 questions at a time

4. Each question should be associated with the answer, brief solution description, type, difficulty level (simple/medium/hard)

## Build a convolution neural network and LDA model — 3

as i doing emotion analysis using cnn ,i give the sample sentence and my code ,you want to calculate how the feature extraction and cnn working ..DONT NEED THEORETICAL EXPLANATION

for LDA i give the sentence and u want to find how probability is calculated and based on that how lda assign topic to document MY BUDGET AND TIME IS LOW

Dont need code

## Math in Payton

I’m new in coding and need to learn how to use mathematics in python without import math and using function.

## Teen Patti Game Winning Probability Logic

I need logic for finding out Winning Probability in Teen Patti 2 Players Game. Go through description carefully.

1. Based on currently dealt card(s) find the best possible hand for player A

1.1 Find the probability of getting best possible hand for player A based on cards dealt and remaining cards in unopened deck

2. Based on currently dealt card(s) find the best possible hand for player B

2.1 Find the probability of getting best possible hand for player B based on cards dealt and remaining cards in unopened deck

3. Based on currently dealt card(s) find the worst possible hand for player A

3.1 Find the probability of getting worst possible hand for player A based on cards dealt and remaining cards in unopened deck

4. Based on currently dealt card(s) find the worst possible hand for player B

4.1 Find the probability of getting worst possible hand for player B based on cards dealt and remaining cards in unopened deck

5. Check the probability of player winning against other player based on their respective best hand and worst hand opening probabilities

5.1 Based on above probabilities rates can be defined. Rates are just decimal value of winning probabilities.

Teen Patti Hands

1. Trio (Three cards of same rank. Eg: A A A)

2. Pure Sequence (Three consecutive cards of the same suit. eg: D9 D8 D7)

3. Sequence (Three consecutive cards not all of the same suit. Eg: S5 H4 D3)

4. Color (Any three cards of the same suit. Eg: SA SQ S10)

5. Pair (Two cards of the same rank. Eg: CK DK HA)

6. High Card (Three cards that do not belong to any of the above types)

## Heart and breathing detection

Hi

I am looking for some help with both ideas and code in Matlab to bring out heartbeat and breathing from a noisy signal which I will supply in a file.

I have already been experimenting with FFT’s but would also like to look at cross correlation adaptive filtering et cetera but really need advice as well on the best way to do it.

The end product will be in an arm cortex M0 so the code can be too bulky or need excessive speed.

Best regards

## convolution neural network model

As am doing emotion analysis of text using [login to view URL] i need to know mathematical working of cnn.i,e if i give a sentence i want to know mathematical calculation of CNN don't need code

## Find formula/code: Can a rectangle can be inscribed in a circle segment?

The problem is to find:

1. Can a particular rectangle fit inside a circle segment?

2. If the rectangle would fit, at what coordinates should it be drawn?

You may express the answers above as mathematical formulas or Javascript statements. Choose what you are comfortable with.

## Spreadsheet to calculate the probability of finding bacteria in food depending on no of samples,weight of samples and no of bacteria

In International trade consignments of milk powder must be tested for bacteria.

Using the Poisson distribution, I can set up a simple spreadsheet to work out the probability using the formula P= 1 -e^- (no of samples (n), weight of sample (w), concentration of bacteria (c)). If I used a value of n=10, w=25 grams and c =0.001 g there is a probability of detecting at least one contaminated sample of 0.22 or 22%. However, I do not know how to do this for the Lognormal distribution.

TASKS

1.I want to employ a coder to make me two spreadsheets similar to the attached Poisson one, one using the Lognormal Distribution and the other, the Binomial Distribution. This must allow me to vary the sample numbers, sample weights and concentration of bacteria to investigate the probability of at least 1 sample being contaminated.

This will take someone familiar with the area a short time to do. But if you are not familiar you will not be able to do it so please do not bid if you are not familiar with acceptance sampling in microbiology.

2.To avoid wasting your time I want the first milestone to be a spreadsheet using the Binomial Distribution. Please try to do this before bidding. If you cannot do this task in 10 minutes using the information below please do not bid.

Note I plan to cancel the project and ask for help from another coder if you cannot meet milestone 1. If you cannot do milestone 1 in 10 minutes or so you will not be able to do the lognormal calculation where most of the money is.

The equation to be used for the Binomial distribution is D = 1 – [1-P^ (1/n)]

Where D= number of defects, P=the confidence limit and n= number of samples. Note sample mass is not taken into account at this point. You will need to modify this function to incorporate sample weight. Note you only need this equation. No need to think about standard deviation etc. You will need to be familiar with logs to rearrange the equation. Please check your solution using the Poisson calculator the results will be slightly different but close enough. If you are way out then your calculations are wrong.

LOG NORMAL DISTRIBUTION

Regarding lognormal. I have attached a paper by Dahms. They cite an assumed standard deviation of 0.8 log-units. I have no equation. And no more information.

WHERE TO GET MORE INFORMATION

These calculations are explained in detail in the book Statistical Aspects of the Microbiological Examination of Foods by Basil Jarvis. This is available as an eBook and is available at a number of download sites.

ABOUT YOUR EXCEL CODING

I need to understand the calculations so you cannot use macros or in-built Excel functions e.g. lognormal.distribution. I am also posting a graphic describing the general relationship between sample nos, sample weight and bacterial concentration. This was determined using the Poisson distribution but will help you validate your own work.
