Machine learning

Machine learning is the practice of teaching a computer to learn. The concept uses pattern recognition, as well as other forms of predictive algorithms, to make judgments on incoming data. This field is closely related to artificial intelligence and computational statistics.

Right now plot_confusion_matrix (and ConfusionMatrixDisplay) always add a color bar.
That's sometimes a bit ugly and also doesn't add that much information if the values are already shown in the heatmap.
Unfortunately it's a bit tricky to remove a colorbar from an axes; I had to employ stackoverflow, not sure if others know it.

in the code-word2vec.py in the path : TensorFlow-Examples/examples/2_BasicModels/
line 155

why the X_embed is divided by "tf.sqrt(tf.reduce_sum(tf.square(X_embed)))"
rather than "tf.sqrt(tf.reduce_sum(tf.square(X_embed) , 1 ) )" ?

Aren't they normalized one row by one ?
thank you.

Current Behavior:

The the wiki page APIExample, for the python example, the handle api is is run through the TessBaseAPIDelete funciton if the api failed to be initialized whereas for the C example below, this is not the case.

python:

rc = tesseract.TessBaseAPIInit3(api, TESSDATA_PREFIX, lang)
if (rc):

Line 1137 of the Caffe.Proto states "By default, SliceLayer concatenates blobs along the "channels" axis (1)."

Yet, the documentation on http://caffe.berkeleyvision.org/tutorial/layers/slice.html states, "The Slice layer is a utility layer that slices an input layer to multiple output layers along a given dimension (currently num or channel only) with given slice indices." which seems to be

Currently as follows:

julia> abstract type Foo{S}; end

julia> struct Bar <: Foo; end
ERROR: invalid subtyping in definition of Bar
Stacktrace:
 [1] top-level scope at REPL[2]:1

Ideally it would at least tell you you forgot a type parameter, and maybe if it's extra nice show you the signature of the thing you're trying to subtype to show you what type parameters it has.

In Transformation Pipeline make class DataFrameSelector for custom transformation and call DataFrameSelector(num_attribs) it show
TypeError: object() takes no parameters
and same with CombinedAttributesAdder

What's the ETA for updating the massively outdated documentation?

Please update all documents that are related building CNTK from source with latest CUDA dependencies that are indicated in CNTK.Common.props and CNTK.Cpp.props.
I tried to build from source, but it's a futile effort.

I was going though the existing enhancement issues again and though it'd be nice to collect ideas for spaCy plugins and related projects. There are always people in the community who are looking for new things to build, so here's some inspiration For existing plugins and projects, check out the spaCy universe.

If you have questions about the projects I suggested,
