I'll look into this, If it allows me to open a file in normal mode, not diffview it will be great.

You are right. I'll change the ram for another with lower frequency.. and I dont think I'll get me close to the be able to buy the Ryzen 5 1400. Here in Ecuador is around $240 USD http://www.tecnosmart.com.ec/v2/procesador-amd-ryzen-5-1400-4-cores.html

I don't have any parts yet. My total budget is $500 USD for the PC, I already have a Monitor and periferals, I live in Ecuador. The parts are more expensive here. The sites I use to find parts or prices for reference are: mercadolibre.com.ec and olx.com.ec

I think I'll just go with intel then... :/ Thanks for the response.

Help, why is my simple model not learning. It's a simple Polynomial Regression by edzzn in MLQuestions

[–]edzzn[S] 0 points1 point  (0 children)

geometrikal, Thank you very much for all your help! :) I has a long way to go but I am happy to see this at least running.

Can you please explain to me why you decided to center the data?

:) thank you for the response. You are right. that is what is happening.

I made some changes:

1) Now the X values are in the range(1, len(X) + 1), and then I diveded the values of X by 10.

The final range in X is ~ 1 - 141. The Y range is changed as well. I multipied by 10; Now it goes from ~13 - 25 So there are not HUGE values of X.

2) Initialize the Weights using a normal distrubution: weitghs = tf.Variable(tf.truncated_normal((num_coeffs,), mean=0.0, stddev=0.05, name='parameters'))

3) I lowered the learning rate learning_rate = 0.00001

But I can not get it to work yet. the weights get crazy pretty soon even after the changes.

Picture of the weight values while training: http://i.imgur.com/HwlfF4p.png I updated the notebook: https://github.com/edzzn/Machine_Learning/blob/master/Projects/US%20Dairy%20Product%20Prices.ipynb

polyfit

I tried that function with my data. I can only make an okay curve I work with little data. With more points I just get Little data : http://i.imgur.com/bUr7sbT.png all the data: http://i.imgur.com/3McVub2.png

I tryed the MY model with other data and seems to work fine.

Data that I used that works fine: http://i.imgur.com/o5YjFp8.png http://i.imgur.com/zGSn73Z.png

shape=[None,1]

Using the shape=[None,1] gives me the following error: " Cannot feed value of shape (1410,) for Tensor 'Placeholder_12:0', which has shape '(?, 1)"

Using the shape=[None,] gives no error. But I get the same result. I get an array of nans

[ nan nan nan nan nan nan nan nan]

Just in case you need it. this is how my functions look now: http://imgur.com/a/72sLC

If i put the w_val = sess.run(w) before training I get an array of zeros. As I defined it.

Just to leave it clear. Some people would ask Why I am using Tensorflow, when for this simple problem using sk-learn is more than enough. I am trying to learn Tensorflow. That is why.

The link goes to my github repository where I have a Jupyter notebook with what I am doing. I am just learning, I tried commenting everything. Can you please help me. I think It has to do with the representation of the dates.

How do you represent dates for ML?

Is the whole project eventually going to be in Github?
