TensorFlow: Machine Learning for Everyone, Rajat Monga 20160222

Rajat Monga, TensorFlow Technical Lead & Manager, Google
TensorFlow™ is an open source software library for numerical computation using data flow graphs. The flexible architecture allows you to deploy computation to one or more CPUs or GPUs in a desktop, server, or mobile device with a single API. TensorFlow was developed by researchers and engineers working on the Google Brain Team for the purposes of conducting machine learning and deep neural networks research.

    If you want a working version at 20:36 …

    import tensorflow as tf
    with tf.Session(graph=tf.Graph()) as sess:
    examples = tf.constant([[1, 2, 3], [5, 6, 7]]) # 2X3 mat
    weights = tf.constant([[1, 1], [2, 2], [3, 3]]) # 3X2 mat
    biases = tf.constant([[1], [2]]) # 2X1 mat
    output = tf.matmul(examples, weights) + biases # 2X2 mat
    print(sess.run(output))

    at 21:48 the code will run if ‘assign_op.run()’ is changed to
    ‘assign_p.eval()’. There’s a subtle difference between the ‘eval’ and ‘run’.

    import tensorflow as tf
    with tf.Session(graph=tf.Graph()) as sess:
    v = tf.Variable([[0.0, 0.0]]) # First init/assign
    tf.initialize_all_variables().run()
    print (v.eval()) # actual evaluation
    assign_op = v.assign(tf.constant([[1.0, 2.0]])) # reassign
    assign_op.eval() # new assignment happens
    print(v.eval()) # actual evaluation

    Every sentence/paragraph starts off strong and clear, and then trails off
    to a mumble. Once he fades to a mumble, the last few words are
    unintelligible.

    Great video. Thanks. I have a question. At time 24:49, why do call
    v.eval(). Isn’t assign_op.run() enough? Thank you.

    Please focus the video recording on the slide content. Views of the speaker
    and the audience are not interesting at all.
